Jason ran around his house 3 times which was a total of 274.5 feet. If the length of his house is 30.5 feet, what is the width o
creativ13 [48]

Answer:

Width of the house is 15.25 feet.

Step-by-step explanation:

Jason ran around his house = 3 times

In this run he covered total distance = 274.5 feet

Perimeter of the house = 2(length + width)

                                       = 2(30.5 + width)

Perimeter of the house is the distance covered by Jason in one round.

So, distance covered in 3 rounds = 3[2(30.5 + width)]

                                              274.5 = 6(30.5 + width)

                                              274.5 = 6(30.5 + width)

                                              45.75 = 30.5 + width

                                               width = 45.75 - 30.5

                                               width = 15.25 feet

Therefore, width of the house is 15.25 feet.

Could someone explain to me how to do this!!
valina [46]

Answer:

x=16, y=39

Step-by-step explanation:

to solve y=2x+7

Substitute 2x+7 for y in y=3x−9

y=3x−9

( solve this like a normal problem)  

2x+7=3x−9 (Add -3x to both sides)

-x+7=-9  (Add -7 to both sides)

-x=-16 (Divide both sides by -1)

x=16

Now that you found x you can substitute this in the other problem.

y=3(16)-9

y=39

Hopefully this helped!
