Multiply 18 * 3 and 20 * 3
18*3 = 54
20 * 3 = 60
Length = 54 cm ; Width = 60 cm
Area = L x W
54 * 60 = 3240
Area = 3240 cm
You make $8.40 per hour $117.60 divided by 14 = $8.40 per hour
Ty makes $8.25 per hour $148.50 divided by 18 = $8.25 per hour
Kim makes $8.60 per hour $137.60 divided by 16 = $8.60 per hour
Kim has the highest pay rate in dollars per hour
Answer: If its .05 cents then only 20 cents to finish the collection I got that because 51 - 47= 4 and if it is .05 cents then I did 4 * 5 = 20
12.60 because 3x1.75=5.25 and 4.2x1.75=7.35 and if you add 5.25 and 7.35 it equals 12.60
I assume you meant -5x+20? If so,
-5(x-4) = 0 This is the answer
x = 4
