Question

Please help me with my math home work

Answer 1

Explanation:

-8/3m = 6

divide both sides by -8/3

m = 6/(-8/3)

m= -2.25

2. 0.8x = 19

x= 19/0.8

x= 23.75

3. 0.12x = 1

x= 1/0.12

x= 8.333333

3/4x = 60

x = 60*(3/4)

x = 45

SORRY I COULDN'T ANSWER EVERYTHING THE QUESTIONS WERE ALOT, BUT WITH MY EXPLANATIONS YOU CAN ANSWER ALL OF THEM. NO SWEAT

Answer 2

page 1:

`-(8)/(3) m = 6`

`-8m = 6(3)`

`-8m = 18`

`m = (18)/(-8)`

`m = -(9)/(4)`

`m = -2(1)/(4)`

page 2:

7)

`0.8x = 19`

`x = 19/0.8`

`x = 23.75`

8)

`0.12x = 1`

`x = 1/0.12`

`x =`
`(25)/(3)`

`x = 8(1)/(3)`

5)

3.3(x+4)

3.3x + 13.2

b.

`9-5\:(1)/(2)x-3\left(-2x+1\right)`

`9-(11)/(2)x-3\left(-2x+1\right)`

`6x-(11)/(2)x+9-3`

`x(1)/(2)+6`

`(1)/(2)x+6`

c.

`2.2(3.1+x)+3x`

`6.82+2.2x+3x`

`6.82+5.2x`

page 3:

1.

3/4 x = 60

x = (60*4)/3

x = 80

2.

2/5 x =42

x = (42*5)/2

x =105

3.

3/5 y = 40

y = (40*5)/3

y =
`(200)/(3)`

y =
`66(2)/(3)`

4.

`-(8)/(3)m =6`

`m = (6*3)/(-8)`

`m = -(9)/(4)`

`m = -2(1)/(4)`

5.

`(5)/(6) x =4`

`x = (4*6)/(5)`

`x =4.8`

6.

`(5)/(3) x =12`

`x = (12*3)/(5)`

`x =7.2`
