Answer:

12 minutes 40 seconds

8 keychains, 95 * 8 = 760 seconds = 760/60 = 12.66667 minutes

= 12 minutes 0.66667*60 seconds

= 12 minutes 40 seconds

Mark’s Pool Repair charges $50 for a service call, plus $40/h for labour. Jennifer’s Pools and Spas charges $30 for a service ca
tatyana61 [14]

Multiply each hourly rate by x ( time to complete the work) add it to the service call for each and then set the equations equal:

50 + 40x = 30 +45x

Subtract 30 from both sides:

20 + 40x = 45x

Subtract 40x from both sides:

20 = 5x

Divide both sides by 5

x = 4

The length is 4 hours.

A family paid $26.400 as a down payment for a home. If this represents 16% of the price of the home, find the price of the home.
Vlada [557]
The correct answer is:

How to find X if P percent of it is Y. Use the percentage formula Y/P% = X

Convert the problem to an equation using the percentage formula: Y/P% = X
Y is 26,400, P% is 16%, so the equation is 26,400/16% = X
Convert the percentage to a decimal by dividing by 100.
Converting 16% to a decimal: 16/100 = 0.16
Substitute 0.16 for 16% in the equation: 26,400/0.16 = X
Do the math: 26,400/0.16 = X
X = 165,000
So $ 165,000 is the price of the home.

I hope this helps you!!
