1. 60m - 15 (4 - 8m) + 20

2. 4 ( 5.8 - 9x) + 8.2 + 22x

3. 9y - 15y +12 - 6y

4. v + 13 - 8 (v + 2)

5. 5/3 (5 + 9) 4/5 (1 - 9x)

Answer 1

`\boxed {1)}` 60m - 15(4 - 8m) + 20

1. Distribute 15 inside the parentheses.
2. 60m - 60 + 120m + 20
3. Combine like terms.
4. 180m - 40

`\boxed {2)}` 4(5.8 - 9x) + 8.2 + 22x

1. Distribute 4 inside the parentheses.
2. 23.2 - 36x + 8.2 + 22x
3. Combine like terms.
4. 31.4 - 14x
5. Reorder so variable is first: -14x + 31.4

`\boxed {3)}` 9y - 15y + 12 - 6y

1. Combine like terms.
2. -12y + 12

`\boxed {4)}` v + 13 - 8(v + 2)

1. Distribute 8 inside the parentheses.
2. v + 13 - 8v - 16
3. Combine like terms.
4. -7v - 3

`\boxed {5)}` 5/3(5 + 9) + 4/5(1 - 9x)

1. Distribute 5/3 and 4/5 inside their respective parentheses.
2. 25/3 + 15 + 4/5 - 36/5x
3. Combine like terms.
4. 362/15 - 36/5x
5. Reorder so variable is first: -36/5x + 362/15
