Solve: 1. 12 + 2 ( x - 1 ) = 4x - 15 - 2x 2. 7 ( x + 3 ) - 1 = 5 ( x + 4 ) + 10
3. ( 4x - x ) 6 + 2 = 11 ( x + 3 ) + 10
4. 3/8 ( 2x - 8 ) = 1/4x + 9

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

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.

false

inverse variation is not exponential
