On a map of a park three inches represents twenty feet. how many inches would represent 12 feet ?

We are given:

3 inches represent 20 feet

Number of inches that represent 12 feet:

Number of inches that represent 1 feet:

We are given the ratio 3 inches:20 feet

dividing both the values by 20

(3/20) inches : 1 feet

Number of inches that represent 12 feet:

We solved for the relation:

(3/20) inches : 1 feet

Multiplying both the values by 12:

(3*12/20) inches : 12 feet

1.8 inches : 12 feet

Hence, 1.8 inches on the map represent 12 feet

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

if x = 1, then the answer is 3.5
