1) u + 2 = 4

u = 2

2)  -5 = s - 3

-2 = s

3) 5/13t = -9

t = -9 × 13/5

t = -39/5

t = -7 4/5

4)  6 = x + 2/3

x = 6 - 2/3

x = 5 1/3

5) 13 + w/7 = -18

w/7 = -18 - 13

w/7 = -31

w = -31 × 7 

w = -217

6) 17 = -13 - 8x

-8x = 17 + 13

-8x = 30

x = 30/-8

x = -15/4

x = - 3 3/4

~Hope I helped!~

*Also, next time, please post your questions individually, so that you could get a quicker answer, thanks! :)

A circular table has a diameter of 4ft.what is its approximate area?(use pi=3)
IceJOKER [234]
Good question if only because it approximates. I imagine you might have been told to do the question in your head.

Area = pi r^2
r = d/2
r = 4/2
r = 2 feet
pi = 3

Area = 3 * 2 * 2 = 12 square feet <<<<<< Answer.

Somewhere in 1 Kings Ch 7, the Bible makes reference to pi being 3. It's a pretty good estimate considering the number system the Bible used.

jeka57 [31]

Answer:

9-x/4=2

\frac{36 - x}{4}  = 2

36 - x = 2 \times 4

36 - x = 8

36 - 8 = x

28 = x

x = 28

21. You are making a rectangular poster to advertise a school fundraiser. You
liubo4ka [24]

The simplified expression for perimeter is 6w, and for area is 2w². 3 meters of a width will allow the most area while not exceeding a perimeter of 20 meters.

Step-by-step explanation:

Let w represent the width of the poster then,

The length of the poster is twice as long as its width, to mean the length is 2w

Perimeter is the distance around the figure. Your figure is a rectangle with sides width, w and length 2w;

Perimeter formula is = 2(l+w) where l is length and w is with

P=2(2w+w) = 2(3w) = 6w meters

Area is given by the product of length and width of the figure

Area=l*w

A=2w*w= 2w²

The table will be;

<u>Width in (m)       Perimeter=6w in (m)           Area (2w²) in m²</u>

3                          6*3= 18                                   2*3²=2*9=18

4                          6*4=24                                  2*4²=2*16=32

Width 3 allows for the most area while not exceeding a perimeter of 20 meters.
