Answer:

C.7 weeks

Step-by-step explanation:

Subtract 60 on both sides then you get: 30w=210, then divide both sides and you get w=7, so it'll take 7 weeks

Answer:

C. 7 weeks

Step-by-step explanation:

30w + 60 = 270

        - 60    -60

subtract 60 from both sides of the equal sign.

30w = 210

We need to isolate the variable, which is (w), so divide both sides by 30.

w = 7

It will take 7 weeks for Uma to save enough money to buy the video game system. So the answer is (c).

The length of a rectangle is 9 inches more than half the width. Find the length if the perimeter is 60 inches.
valentina_108 [34]

Answer:

Length = 10.435 inches

Step-by-step explanation:

Let the length be l

Let the width be w

Since the length is 9 inches more than half the width.

Then;

L = 0.5w + 9

Perimeter of a rectangle is;

P = 2Lw

Thus;

P = 2w(0.5w + 9)

Since perimeter = 60

Then;

2w(0.5w + 9) = 60

w² + 18w = 60

w² + 18w - 60 = 0

From quadratic formula;

w ≈ 2.87 in

L = 0.5(2.87) + 9

L = 10.435 in
