10x+2=32
-2 -2
10x=30
/10 /10
x=3
Your Answer is
x=3Hope This Helps! Brainliest Would Be Greatly Appreciated.Answer:
x=3
Step-by-step explanation:
the first step is to subtract 2 from both sides because you want to isolate the variable, and the opposite of addition is subtraction. so, you do 10x + 2 = 32, and when you subtract 2 from both, you get 10x = 30. then, because 10 and x are being multiplied together, you want to divide both sides by 10 to get x alone. so, you get x = 30/10, so x = 3.
If hot and cold water taps are turned on altogether, a bath is filled in three minutes but if the cold tap was only half opened it would take one minute forty eight seconds longer. How long would the hot tap alone take to fill the bath?
9514 1404 393
Answer:
12 minutes
Step-by-step explanation:
Let c and h represent the filling times for the cold and hot taps, respectively. When the cold tap is 1/2 open, we presume that means the filling time becomes 2c.
In terms of baths per minute, the relationships are ...
1/c + 1/h = 1/3
1/(2c) +1/h = 1/(3 +1.8) . . . . . 1:48 min:sec is 1.8 minutes
Subtracting the first equation from twice the second, we get ...
2(1/(2c) +1/h) -(1/c +1/h) = 2(1/4.8) -(1/3)
1/h = 2/4.8 -1/3 = 1/12
h = 12
It takes the hot tap 12 minutes to fill the tub alone.

What is the binomial expansion of (2x – 3)5? (2x)5 – 15(2x)4 + 90(2x)3 – 270(2x)2 + 405(2x) – 243 (2x)5 + 15(2x)4 – 90(2x)3 + 270(2x)2 – 405(2x) + 243 (2x)5 + 15(2x)4 + 90(2x)3 + 270(2x)2 + 405(2x) + 243 2(x)5 – 30(x)4 + 180(x)3 – 540(2x)2 + 810(x) – 243
Answer:

The value of binomial expansion of expression (2x - 3)⁵ is,
⇒ (2x)⁵ – 15(2x)⁴ + 90(2x)³ – 270(2x)² + 405(2x) – 243
We have to given that;
The expression is,
⇒ (2x - 3)⁵
Now, We know that;
The formula of binomial expansion is,
⇒ (x + y)ⁿ = (ⁿ₀) xⁿy⁰ + (ⁿ₁) xⁿ⁻¹y¹ + (ⁿ₂) xⁿ⁻²y² + ...... + yⁿx⁰
Hence, The value of binomial expansion of (2x - 3)⁵ is,
⇒ (2x - 3)⁵
⇒ (2x + (- 3))⁵
⇒ (2x)⁵ – 15(2x)⁴ + 90(2x)³ – 270(2x)² + 405(2x) – 243
Thus, The value of binomial expansion of expression (2x - 3)⁵ is,
⇒ (2x)⁵ – 15(2x)⁴ + 90(2x)³ – 270(2x)² + 405(2x) – 243

The equation for this graph is y = x +
Answer:
y=3x+2
Step-by-step explanation:
The y intercept is 2. Therefore, we can plug 2 into b in y=mx+b because b is a y intercept.
The slope is 3 because if you go up 3 and right to the one (rise over run) the line will go through it. You can also make is -3 over -1 but that would just equal 3.

Lane is making accessories for the soccer team. He uses 721.54 inches of fabric on headbands for 41 players and 2 coaches. He also uses 361.21 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player? Please answer quick pls
Answer:
16.78 inches of fabric was used for headbands for each player and 8.81 inches of fabric was used for wristbands for each player
Step-by-step explanation:
Lane is making accessories for the soccer team.
For headbands
He uses 721.54 inches of fabric on headbands for 41 players and 2 coaches.
Hence:
Let the number of inches used for headbands be represented by x
41x + 2x = 721.54
43x = 721.54
x = 721.54/43
x = 16.78 inches
Hence the number of inches used to make head band for 1 player is 16.78 inches
He also uses 361.21 inches of fabric on wristbands for just the players.
We have 41 players hence:
41 players = 361.21 inches
1 player = x
41 × x = 1 × 361.21 inches
x = 361.21 inches/41
x = 8.81 inches
8.81 inches of fabric was used for wristbands for each player.
Hence:
16.78 inches of fabric was used for headbands for each player and 8.81 inches of fabric was used for wristbands for each player

A new law has support from some Democrats and some Republicans. This two-way frequency table shows the proportion from each political party that does or does not support the new law. Which conclusions can be made from this table? Select each correct answer. For both parties, more members do not support the law than support the law. Among Democrats, a larger percentage do not support the law than support the law. More Republicans support than the law than do not support the law. Compared to the Republicans, the Democrats have a larger percentage of members who support the law.
Answer:
Step-by-step explanation:
Political parties are organized groups of people with similar ideas or ideology about the function and scope of government, with shared policy goals that work together to elect individuals to political office, to create and implement policies, to further an agenda, and to gain control of the government and the policy-making process. Parties gain control over the government by winning elections with candidates they officially sponsor or nominate for positions in government. Political parties nominate candidates to run many levels of government including the national level, Congress, and the presidency; but, they nominate for state and local levels as well. They also coordinate political campaigns and mobilize voters.
Political parties are points of access/linkage institutions available to the public, though they are not themselves government institutions. Neither interest groups nor political parties are directly mentioned in the U.S. Constitution. Where interest groups often work indirectly to influence our leaders, political parties are organizations that try to directly influence public policy through nominating and officially sponsoring members who seek to win and hold public office. This is a key difference. Interest groups do not officially nominate or nominate candidates for public office, although they may support them politically and even contribute dollars to their campaign.
Parties accomplish this by identifying and aligning sets of issues that are important to voters in the hopes of gaining support during elections. In this respect, parties provide choices to the electorate, something they are doing that is in sharp contrast to their opposition. These positions on these critical issues are often presented in campaign documents or political advertising. During a national presidential campaign, they also frequently reflect the party platform, which is adopted at each party’s presidential nominating convention every four years.
If successful, a party can create a large enough electoral coalition to gain control of the government. Once in power, the party is much more likely to be able to deliver, to its voters, the policy preferences they choose by electing its partisans to the government.Political parties organize political campaigns to win public office for those they nominate.

jamil buys 4 books and some pens each book costs £5.95 each pen costs £2.35 the toal costs of the books and the pendulum is £37.90 work out how many pens jamil buys
Answer:
9.68
Step-by-step explanation:
it makes sense when u tink about ot
Answer:
Jamil buys 6 pens.
Step-by-step explanation:
Jamil buys 4 books and each book costs £5.95. With 5.95+5.95+5.95+5.95 = £23.80. We have the total price for the books. The total cost of books and pens is £37.90 and each pen costs £2.35. If we keep adding £2.35 to our £23.80, we will get £37.90. If we add 23.80+2.35+2.35+2.35+2.35+2.35+2.35 = £37.90. We now have our total amount, and the prices of the amount of books and pens Jamil bought. Jamil bought 6 pens as it equals to £37.90.

what is the slope and y-intercept of this graph?
Answer:
Slope is 2
Y-intercept is 7
Step-by-step explanation:
To find the slope we take any two points from the table
and use it in the formula :
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\[/tex]
we take the points (0,7) and (1,9)
now we put these points in the formula and it becomes
[tex]m=\frac{9-7}{1-0}[/tex]
[tex]m=2[/tex]
so our slope which is m is 2 and now for the y-intercept we use the standard equation
[tex]y=mx+c[/tex]
where c is the y-intercept
we use the value of m which is 2 and use any point from the table lets take (0,7)
[tex]y=mx+c\\7=(2)(0)+c\\7=c[/tex]
our y-intercept which is c is 7
so finally our slope is 2 and y-intercept is 7

Julio says, If you subtract 18 from my number and multiply the difference by −4, the result is −20. What is Julios number?
Answer:
Julio's number is 40
Step-by-step explanation:
"If you subtract 17 from my number and multiply the difference by negative 4, the result is negative 92.
n= number
(n-17)*(-4) = -92
distribute
-4 *n - 17*(-4) = -92
-4n +68 = -92
subtract 68 from each side
-4n +68-68 = -92 -68
-4n = -160
divide each side by -4
-4n/-4 = -160/-4
n = 40

7y+2<5y+12
Answer:
y < 5
Step by step:Step 1: Subtract 5y from both sides.
7y+2−5y<5y+12−5y
2y+2<12
Step 2: Subtract 2 from both sides.
2y+2−2<12−2
2y<10
Step 3: Divide both sides by 2.
[tex]\frac{2y}{2}[/tex] < [tex]\frac{10}{2}[/tex]
