Answer:

So there’s two cell phones the length on first is 8.4 inches the width on the first cell phone is 5.6 inches. On the second cell
Olin [163]

Answer:

The width, in inches of the larger cell phone is 6.14 inches.

Step-by-step explanation:

To solve we must set up a ratio.

\frac{8.4}{5.6} = \frac{9.21}{y}

After setting this ratio up, we can cross multiply to solve for y.

8.4(y) = 5.6(9.21)

8.4(y) = 51. 576

To get y alone we divide by 8.4 on both sides.

y = 6.14

The width, in inches of the larger cell phone is 6.14 inches.
