question 9 2(x+10)

srry i dont know all of the answers because i didnt have these on my test but the ones i answered are all correct tm on this have a great day.

Answer 2

Q.1   x-2/5=7

divide -2/5 which is -0.40

x-0.40=7. Move -0.40 to the right side of the equal sign and that becomes +0.40

x=7+0.40 . 7+0.40 is 7.4

x=7.4

Q.2   2.1r=6.174

divide 2.1 by both sides which 2.1r divided by 2.1 is 1r and 6.174 divided by 2.1 is 2.94

r=2.94

Q.3

equation:  2/3 = 32 2/3 d

Q.4    x9=3/5

3/5 is 0.60

x9=0.60

divide 9 by both sides. 9x divided by 9 is 1x and 0.60/9 is

0.0 6666 (the 6 is continuing)

x=0.06666

Q.5  

x=-3

Q.6

7.25 =0.5x

divide 0.5 by both sides. 0.5x divided by 0.5 is 1x and 7.25 divided by

0.5 is 14.5

x=14.5

Q.7

the expression: 7-9m
