23x−15x=x−1
8x = x - 1
8x - x = x - 1 - x
7x = -1
x = -1/7
Use the following table to determine P(X>4).
Answer:
0.11
Step-by-step explanation:
To get the probability above, we simply look for the events greater than 4, then add their probabilities
That is;
P(5) + P(6) + P(7)
So the probability in this case will be;
0.07 + 0.03 + 0.01 = 0.11

How do I solve this equation and check all the solutions?
Answer:
10
Step-by-step explanation:
x-√2x-5=5
-√2x-5=5-x
√2x-5=-5+x
2x-5=x²-10x+25
2x-5-x²+10x-25=0
12x-20-x²=0
-x²+12x-20=0
x²-12x+20=0
x=10
Note: there is a another answer x=2 but the equality will be false if x=2 so the answer is 10
Solve for x and graph the solution on the number line below.

Anelle is saving to buy a guitar that costs $350. So far she has saved $105.20. She wants to buy the guitar in 18 weeks. Based on this information, which statement is true?
Answer:
Step-by-step explanation:
350-105.20= 244.80 is still needed
I don't have the statements so...
244.80/18 weeks = 13.60 She'll need to save at least $13.60 a week for 18 weeks to make up the difference.
Answer:
Step-by-step explanation:
18x + 105.2 ≥ 350
18x ≥ 244.8
x ≥ 13.6
She has to save at least $13.6 per week.

Solve -4b + 2 = 18.
b =
Answer:
b = -4
Step-by-step explanation:
your equation: -4b + 2 = 18
subtract 2 from both sides: -4b = 16
divide both sides by -4 to isolate the variable: b = -4
Answer:
b= -4b=18-2
=16
b=16+(-4)
=12

Answer:
[tex]x=155[/tex]
Step-by-step explanation:
According to the definition of a linear pair:
[tex](x-25)+(50)=180[/tex]
Solve for [tex]x[/tex].
Combine like terms on the left:
[tex]x+25=180[/tex]
Subtract 25 from both sides:
[tex]x=155[/tex]
Hence, the value of [tex]x[/tex] is 155.
Answer:
x=155, the angle is 130 degrees
Step-by-step explanation:
Assuming you want to find x:
A straight line is 180 degrees so that means
x-25+50=180 add like terms together
x+25=180 subtract 25 from both sides
x=155
If you want to find the degree angle, just replace x with 155
x-25=155+25=130

After restocking the vending machine, Sonya determined that 2 packs of mints were sold for every 6 packs of gum. If a total of 160 packs of candy were sold, how many were packs of gum?
Answer:
80
Step-by-step explanation:
160÷2=80 yay!!!!!!!!!!!
Answer:
(By mints I hoped you meant candy) 480 packs of gum
Step-by-step explanation:
2 packs of candy for every 6 packs of gum. Divided beach side by two to get ration of 1:3. This means that for every 1 pack of candy 3 packs of gum are sold. 160 x 3 = 480.

[6+(10-8)*7]+5.
*need help ASAP*
Step-by-step explanation:
Given
[ 6 + ( 10- 8 ) *7 ] + 5
= [ 6 + 2 * 7] + 5
= [ 6 + 14 ] + 5
= 20 + 5
= 25
Answer:
25
Step-by-step explanation:
Using PEMDAS, you start by evaluating the expression in parentheses:
(6 + (2) × 7 ) + 5
Since there are no exponents, you do the multiplication/division next:
(6 + 14) + 5
Then add the rest:
(20) + 5

Type an (x,y) ordered pair that is a solution to this
equation.
Answer:
The ordered pair is (4,6)
Step-by-step explanation:
Ordered Pairs
It's given the equation
y = x + 2
Since there are no restrictions for the values of x and y, it has infinitely many solutions, i.e. any ordered pair of values (x,y) that make true the equation is a solution.
We can pick any value for x and then calculate the corresponding value for y as follows:
For x = 4,
y = 4 + 2 = 6
The ordered pair is (4,6)

How do I solve this equation and check the solutions?
Answer: x = -10 or 2
Step-by-step explanation:
Given:
√20 - 8x = x
Step 1: Square √20 - 8x
(√20 - 8x)² = (x)²
20 - 8x = x²
Now we can solve the problem
Step 2: Move 20 - 8x to the other side
20 - 8x = x²
-20 + 8x - 20 + 8x
0 = x² + 8x - 20
This is a quadratic equation
Step 3: Factor the quadratic equation
10(-2) = -20 and 10 - 2 = 8
So our factors are 10 and -2
(x + 10)(x - 2) = 0
Step 4: Create a FOIL equation
For this equation to be true, x would have to make either one of the parenthysis equal to zero
(x + 10)(x - 2)
x = -10 x = 2
10 - 10 equals zero, and -2 + 2 equals zero, so those are your answers.
In how many ways can the numbers 3, 4, 5, 6, 7, 8, 9, and 10 be divided into two sets A and B such that the sum of the numbers in B is three times the sum of the numbers in A?
Answer:
4 ways
Step-by-step explanation:
3+4+5+6+7+8+9+10=52
1/4×52=13
13×3=39
3+10=13
4+9=13
5+8=13
6+7=13
so there are 4 ways to divide in two parts.
1.
A={3,10}
B={4,5,6,7,8,9}
2.
A={4,9}
B={3,5,6,7,8,10}
3.
A={5,8}
B={3,4,6,7,9,10}
4.
A={6,7}
B={3,4,5,8,9,10}

A pile of pebbles has a weight of 95 kg.
Some of the pebbles put into a small bag.
The rest of the pebbles is put into a large bag.
The pebbles in the large bag weighs 45 kg more than the pebbles in the small
What is the weight of the pebbles in the large bag?
Answer:
70kg
Step-by-step explanation:
s = small bag
b = big bag
Equations
s + b = 95
s + 45 = b
plug in
s + s + 45 = 95
2s + 45 = 95
2s = 50
s = 25
plug in to find big bag
25 + 45 = b
70 = b
Answer:
The weight of the pebbles in the large bag is 70kg.
Step-by-step explanation:
This looks like a substitution algebra problem. To do this, I’m going to mark the large bag with (L) and the small bag with the variable, (s). I will make first 2 equations to show the value. The first equation would be L=45+s. The second equation would be 95=L+s. Since L is literally 45+s, add this into the 2nd equation. This would be 95=45+s+s. You should have 95= 45+2s and you would subtract 45 from both sides then. Finally, divide 2s by 2 to get what the small bag weighs, (which is 25kg). To find the large bag’s weight, use the first equation to find the answer. L= 45+s or 25. The answer would bring us to 70 kg.
