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

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
