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).

Which of these is equivalent to the following expression? 5s - 11b + 3s - 12b A. -b + 8s -B.23b + 2sC. -23b + 8s D. b + 8s
Marina86 [1]

Answer:

Option b) and c) are correct

Step-by-step explanation:

Given expression is  5s - 11b + 3s - 12b

5s - 11b + 3s - 12b=8s-23b (Rearranging the right hand side terms)

5s - 11b + 3s - 12b =-23b+8s

Option c) is correct

By the definition of equivalent the given expression is the sum of the two terms ( the terms may vary or equal)

From the definition of equivalent we get, Option b) is also correct

Therefore  Option b) and c) are correct

Workout the area of the quarter of a circle with a radius of 8
QveST [7]

Answer:

16\pi

Step-by-step explanation:

We need to find 1/4 of the area of a circle with a radius of 8

Let r be radius

Area of a circle = r^{2} \pi

Substitute r with 8

Area of a circle = 8^2\pi =64\pi

Now, to find 1/4 of the area, we can create an equation \frac{64\pi }{4}={16\pi

The answer is 16\pi

Hope this helps :)

Have a spectacular day!

The dimensions (width and length) of room1 have been read into two variables : width1 and length1 . The dimensions of room2 have
Lorico [155]

Answer:

Total area of the two rooms   =   (width1length1) +   (width2length2)

Step-by-step explanation:

The area of the rectangular shape is given by = Length * breadth

Therefore the area of the two rooms can be calculated using the above formula when the variables lengths and widths are given.

Area 1= Area of the first room = length * breadth=  (width1length1)

Area 2=Area of the second room = length * breadth=  (width2length2)

Total area of the two rooms = Area1 + Area 2

                                         =   (width1length1) +   (width2length2)
