In the following proportion, what does y equal? y=39
4 30

A. 156

B. 13

C. 5.2

D. 1.4

C

Step-by-step explanation:

y / 4 = 39 / 30

y / 4 = 1.3

y / 4 * 4 = 1.3 * 4              (What you do to on side you also do to the other)

y = 5.2

So, your answer should be C, 5.2

-14 is the answer

hope this : ))

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.
