The equation would be 0.05x + 3.15 = 5.10

The ratio of the width to the length of a painting is 3 to 7. If the painting is 42 in. long how wide is it
belka [17]

If length is 42 inches, then width is 18 inches.

Step-by-step explanation:

We are given ratio of width to the length of a painting i.e 3 to 7. If the painting is 42 inches long, then how wide it is?

Solving:

\frac{width}{length}=\frac{width}{length}\\ \frac{3}{7}=\frac{w}{42}\\  Cross\,\,multiply:\\3*42=w*7\\126=w*7\\w=\frac{126}{7}\\w=18

So, If length is 42 inches, then width is 18 inches.
