Answer:

x=-13

Step-by-step explanation:

x+5/2=-4

we need to isolate x, so the first thing we do is get rid of the thing being divided by x, by doing the opposite: we multiply

(2) x+5/2 =-4(2)

x+5=-8

subtract 5 from both sides to isolate x

x+5-5=-8-5

x=-13

….."………….."……how do u do dis?
raketka [301]

Answer:

x = -25

Step-by-step explanation:

3 -  \frac{x}{5}  = 8

5(3 -  \frac{x}{5} ) = 5 \times 8

5 \times 3 - 5 \times  \frac{x}{5}  = 5 \times 8

15 - 5 \times  \frac{x}{5}  = 40

15 - x = 40

- x = 40 - 15

- x = 25

x =  - 25

the perimeter of a pool table is 30 ft.The table is twice as long as it is wide.what is the length of the pool table.
noname [10]
Perimeter is legnth +legnth + width + width or
P=2L+2W

L=2W
subsitute L=2W for L in P=2L+2W

P=2(2W)+2W
P=4W+2W
P=6W

we know that Perimiter=30 so
30=6W
divide both sides by 6
5=Width

subsitute W=5 for W in L=2W
L=2(5)
L=10

to check
10=2(10)+2(5)
30=20+10
30=30
checks


Legnght=10
Width=5
