Solve the following problem using cross-multiplication. Ja’Quin draws a picture of a horse that measures 7 inches by 4 inches. He increases the size of the picture on a photocopier so that its new width is 6 inches. What is the new length of the picture? Round to the nearest tenth.(1 point)

1.5
1.2
10.5
42.0

Answer 1

To solve this problem using cross-multiplication, we can set up a proportion:

7 inches / 4 inches = 6 inches / x inches

Now, cross-multiply to solve for x:

7 * x = 4 * 6
7x = 24

Now, divide both sides by 7 to solve for x:

x = 24 / 7
x ≈ 3.43 inches

So, the new length of the picture is approximately 3.4 inches. The closest answer choice is 1.2 inches.
