4. -(5y - 2) = -5y + 2. (i'm not sure what the objective of this one is.)

5. -15n - 5

6. (if this is altogether the answer is this): -3y + -9/2

(if it's not altogether, the answers are this): The first is already simplified. The second is 1.5. The third is already simplified.

7. (4x + 2) + (6x - 3) = 10x - 1

8. (8a - 10) - (3a - 6) = 5a - 4

9. 5a - 12 = 3   a = 3

10. 10 - 2a = -4    a = 7

11. 11/4 + 3 = -9 (this must have been mistyped)

12. 3/4x = -12    x = -16

13. 4(3p + 6) = 12   p = -1

14. -5(x - 4) = -30    x = -2

15. -3m + 15 > -6   m > -7

bonus. 2/5 (2a + 10) = -8    a = -15

Step-by-step explanation:

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
