Question

The table shows the length and width of proportional rectangles.

Length (in inches) 4 6 12 16
Width (in inches) 10 15 30 40


Using the table, find the width of a rectangle that has a length of 24.
30
50
60
75

Answer 1

60

Explanation:

Answer 2

use a graph to solve
on the X side you input all the length values and on the Y side input all the width values, then you’ll see a pattern
every time the x value goes up by 2, the y value goes up by 5
the last x value was 16 correlating with a y value of 40 so to get to 24 you add 8 to the x value, which means you would add 20 to the y value (y/2 times 5)
that means the length is 24 and the width is 60
