i am timed pls quick if you actually know the answer

Answer:

y = 245 / 7, x = 29

Step-by-step explanation:

make both into ax + by = c format which is

Math:

5x + 2y = 245

-5x + 5y = 30 <== 5 (- x + y = 6) to cancel out the x since it has a negative already.

[(Side Note) if both were positive then you would need to do

EX: - 5 (- x + y = 6)]

Continued:

7y = 275 ==> 7y/7 = 245/7

y = 245 / 7

Plug it in the most convenient one which has the equation y = x + 6

and tweak it a bit

x = y - 6

x = 245 / 7 - 6 ==> 245 / 7 - 42 / 7

x = 203 / 7 ==> 29

Answer:

x = 20

Step-by-step explanation:

2x + 2x + 10 = 90

4x + 10 = 90

4x = 80

x = 20

Answer:

Angle AOB is made up of angle AOC and COB.

AOC + COB = AOB

Since AOB is a right angle, it is 90°.

Using the values given, AOC = [tex]2x[/tex] and COB = [tex]2x+10[/tex].

Therefore,

[tex]2x+2x+10=90[/tex]

Subtract 10 from both sides:

[tex]2x+2x+10-10=90-10[/tex]

[tex]2x+2x=80[/tex]

[tex]4x=80[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4} =\frac{80}{4}[/tex]

[tex]x=20[/tex]

Answer:

-15x + 3

Step-by-step explanation:

expand

3 times -5x = 15x

3 times 1 = 3

Answer:

−15x+3

Step-by-step explanation:

3(−5x+1)

= (3)(−5x+1)

= (3)(−5x)+(3)(1)

= −15x+3

1. How many cups of seed does Zack need to fill both bird feeders? Show how you found your answer

    [] He will need 5 cups of seed to fill both bird feeders

              [] 2 1/2 * 2 = 5

2. Write an expression for the number of scoops Zack needs to fill both feeders

    [] 1/4x = 5

              [] If his scoop hold 1/4 cup, then however many scoops (x) he does should equal 5.

3. Evaluate the expression to find the number of scoops Zack needs. Show your work

    [] 20 scoops

              [] 1/4x = 5 -> x = 20

Have a nice day!

Answer:

Craig has

$25−$5.25 for shoes. In other words, he has $19.75 Now when you divide this amount by $4.00, you will get numbers of games he played.

$19.75

$4

=4.9375

or only 4 games.

Step-by-step explanation:

Answer: 4 games

Step-by-step explanation: 25-5.25=19.75

19.75 divided by 4 = 4.9375 (but let's say its 4)

Or you could use the subtraction way 19.75 - 4 and continue until you cant subtract it by 4 anymore

The changes he be left with us $3.75

-175°C

hope helpful <3

-175 degrees because it is grater than -173 degrees C

The open side of the inequality sign indicates the larger number. So 5 > 3, 4 < 6.

This, ≥, means it is bigger than or equal.

To show < or >, the purple arrow points to where the unknown value (x or n or k or b etc.) could be, and the dot is unfilled, or white, indicating that number is not a possible value of the unknown number.

To show ≤ or ≥, the purple arrow works the same way, it points to the where the unknown value could be. But the dot is filled, showing that the number could be the unknown value.

So for question 11, the answer is x ≤ 0 (x is less than or equal to zero).

For question 12, the answer is x > 3 (x is more than three)

Hope this helped :)

Answer:

14

Step-by-step explanation:

Answer:

14

Step-by-step explanation:

Answer: The answer is B.

Step-by-step explanation:

To figure out, you must first turn the mixed fraction (3 1/2) into an improper fraction (7/2). We can do so by:

3 * 2 = 6

6 + 1 = 7 or 7/2

Next, you follow the rules of KCF: Keep, Change, Flip. Keep the first fraction, Change the sign to its inverse operation, and Flip the second fraction.

Our original equation is 7/2 /(divided by) 3/2 = ?

1. Keep the first fraction

7/2 / 3/2 = 7/2 / 32

2. Change the sign to its inverse operation

7/2 / 3/2 = 7/2 * 3/2

3. Flip the second fraction

7/2 * 3/2 = 7/2 * 2/3

Now, solve.

7/2 * 2/3

7 * 2 / 2 * 3 = 14/6

To make this a proper mixed number, first simplify.

14/6 / 2 = 7/3

Now, figure out how many wholes are in 7/3.

7/3 / 3 = 2 1/3

This is because 2 times 3 is six, and 7 minus 6 equals 1, or 1/3.

Therefore, the answer is 7/3 OR 2 1/3 OR B
