ANSWER WITH STEPS:
Let's solve for x.
5x−10y=−5
Step 1: Add 10y to both sides.
5x−10y+10y=−5+10y
5x=10y−5
Step 2: Divide both sides by 5.
5x
5
=
10y−5
5
x=2y−1

Answer:
15.6 ft
Step-by-step explanation:
Since the sails are similar then the ratios of corresponding sides are equal.
Comparing the shortest sides, that is
10 : 6 = 5 : 3
let the longest side be x, then using proportion
= ( cross- multiply )
5x = 78 ( divide both sides by 5 )
x = 15.6
The longest side is 15.6 ft
You would use unit rate for this. If Austin makes $209 in 11 hours, then he makes 209/11 = 19 dollars in 1 hour.
Then, we can make a proportion:
$19/1 hour = $152/ x hours
Cross multiply:
152 = 19x
Solve for x to get:
x = 8 hours.
The answer is to what is 5/2 divided by 1/4 is 10
