What is the solution to the proportion?
5/x = 2/16

a. x = 6.4

b. x = 1.6

c. x = 30

d. x = 40

D. x = 40

Step-by-step explanation:

We can use cross products to solve this proportion

5          2

=

x            16

5 * 16 = 2x

80 = 2x

Divide by 2

80/2 = 2x/2

40 =x

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
