The measurements of the segments fall on similar triangles. This means the lengths of each segment can be found using proportions.
Remember, a proportion is an equation which sets equal ratios equal to each other.
To solve for c, multiply numerators and denominators across the equal sign:
24c = 32(15)
24c = 480
c = 20
Answer:
9000

$9000.
the profit is $9000
Answer:
6/5
Step-by-step explanation:
you multiply by 2
28/21=42/x multiply both sides by x
28/21x=42 divide by 28/21 on both sides ( or multiply both sides by 21/28)
X= 63/2
X= 31 1/2
