UPS charges $7 for the first pound, and $0.20 for each additional pound. FedEx charges $5 for the first pound and $0.30 for each additional pound. How many pounds will it take for UPS and FedEx to cost the same? Write an equation

At 20 pounds it will UPS and FedEx will cost the same!

Step-by-step explanation:

For UPS, we can write the equation y= 7 + .20x  since .20 is the coefficient and 7 is the constant. FedEx's equation would be y= 5 + .30x

 Next, set the equations equal to each other: 7 + .20x = 5 + .30x

Now solve for x:     7 + .20x = 5 + .30x

                              -5                     -.20

                                      2 = .10x

                                      20 = x

At 20 pounds it will UPS and FedEx will cost the same!

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
