Question 1
What value of v makes the
equation true?
5(5 + 5v) =-29 + 7v

v = - 3

Step-by-step explanation:

Given

5(5 + 5v) = - 29 + 7v ← distribute parenthesis on left side

25 + 25v = - 29 + 7v ( subtract 7v from both sides )

25 + 18v = - 29 ( subtract 25 from both sides )

18v = - 54 ( divide both sides by 18 )

v = - 3

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
