Subtract 7x from both sides
3=9x-13-7x
simplify 9x-13-7x to 2x-13
3=2x-13
Add 13 to both sides
3+13=2x
simplify 3+13 to 16
16=2x
simplify both sides by 2
16/2=x
simplify16/2 to 8
x=8

Solve for x. Show each step and explain.<br> 4.5(8-x)+36=102-2.5(3x+24)
lianna [129]

Answer: x= -10

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4.5(8−x)+36=102−2.5(3x+24)

(4.5)(8)+(4.5)(−x)+36=102+(−2.5)(3x)+(−2.5)(24)(Distribute)

36+−4.5x+36=102+−7.5x+−60

(−4.5x)+(36+36)=(−7.5x)+(102+−60)(Combine Like Terms)

−4.5x+72=−7.5x+42

−4.5x+72=−7.5x+42

Step 2: Add 7.5x to both sides.

−4.5x+72+7.5x=−7.5x+42+7.5x

3x+72=42

Step 3: Subtract 72 from both sides.

3x+72−72=42−72

3x=−30

The probability distribution for the number of goals the Lions soccer team makes per game is given below.
UkoKoshka [18]

Answer:

The correct answer is:

(A) 0.55

Step-by-step explanation:

This probability distribution means that we have these following probabilities:

P(X = 0) = 0.05

P(X = 1) = 0.15

P(X = 2) = 0.35

P(X = 3) = 0.30

P(X = 4) = 0.15

What is the probability that in a given game the Lions do not score more than 2 goals?

This is the following probability.

P = P(X = 0) + P(X = 1) + P(X = 2)

P = 0.05 + 0.15 + 0.35

P = 0.55

The correct answer is:

(A) 0.55

What is the image point of (-6, -9) after a translation left 1 unit and down 5 units? ​
kvv77 [185]

Answer:

(-7,-14)

Step-by-step explanation:
Going left is adding a negative value, so it would be -6-1 which is -7 for the x value and going down 5 units is also a negative value so it would be -9-5 which is -14 giving you (-7,-14)
