Question

Math help mee plzzzzzz THERE IS A ATTACHMENT SO WAIT AT LEAST 30 SECONDS PLZZZZ

Answer 1

10. 2800 = 500 + 2x
     -500    -500
2x = 2300
/2      /2

x = 1150
the cost for one month is $1150

11. 20-3h=2
    -20       -20

-3h = -18
/-3     /-3

h = 6

12. g/7-15=-12
           +15 +15
g/7=3 >>   (7/1)*(g/7) = 3(7)

g = 21

13. 17= p-3-3p
2p-3=17
    +3 +3
2p = 20
/2     /2

p = 10

14. -4(r+6)=-63 (distribute)
-4r-24=-63
     +24 +24

-4r = 39
/-4    /-4

r = -9 3/4

15. 4x+3(x-2)=-20
4x+3x-6=-20
         +6   +6

7x = -14
/7     /7

x = -2

16. 3n-5=7n+11
      -3n   -3n

7n-11=-5
    +11 +11

7n = 6
/7    /7

n = 6/7

17. -6a+3=-3(2a-1) 
     /-3         /-3

-2a+1=-2a+1
+2a-1 +2a-1

0 = 0

18. 2y+5=1/2(4y+8) >> multiply both sides by 2/1
2(2y+5)=4y+8

4y+10=4y+8
-4y     -4y

10 $\neq$ 8

Answer 2

I hope this helps you
