Answer:

(2x+16) + (x) = 180

How do y'all substract negative number wen substracting
Nesterboy [21]
Suppose the equation went like this
-12 -24= x
You would essentially just add them together and put a negative sign in front of it so the answer would be -36. But once you start dealing with parentheses and brackets it get more complicated than that. Comment if you have any more questions :)

Greg drove 660 miles in 12 hours. At the same rate, how long would it take him to drive 495 miles?
Slav-nsk [51]

This one has two parts, first we have to find out the speed to drive 660 miles in 12 hours.  Divide 660 by 12 to get the speed of 55 miles per hour, that is your rate for the next part.

Next we need to find out how long it will take to drive 495 miles at the same pace of 55 mph.

Do the same thing 495/55.  That will give you your final answer.

495/55= 9

It will take him 9 hours to drive 495 miles at a rate of 55 mph.

The area of a playground is 168 yd2. The width of the playground is 2 yd longer than its length. Find the length and width of th
77julia77 [94]

Answer:

Length = 12yards

Width = 14yards

Sum = 26yards

Step-by-step explanation:

Let assume the play ground is rectangular in form.

Area of a rectangle = length × width

Given area of the playground = 168yd²

If the width of the playground is 2yd longer than its length, then:

W = L+2

Substituting W = L+2 into the formula above we have:

A = L × (L+2)

A = L²+2L

168 = L²+2L

L²+2L-168 = 0

L²+14L-12L-168 = 0

L(L+14)-12(L+14) = 0

(L-12)(L+14) = 0

L-12 = 0 and L+14 =0

L = 12 and -14

Taking the positive length, L = 12yards

If Length = 12yards

W = L+2

W = 12+2

Width = 14yards

Sum of the length and width will be:

L+W= 12+14

= 26yards
