Question

HELP ME PLEASE IM ONLY A FRESHYMANS IM CRYING IN MY BED FEEL PITY AND HELP ME PLSSSSS

Answer 1

Explanation:

4. : Multiplication Equality

Addition Equality

Check:

`5 - 2y = 19`

`- 2y = - 14`

`y = 7`

5.

Division Equality

Multiplication Equality

Subtraction Equality

Check:

`(5m)/(4) - 3 = - 13`

`(5m)/(4) = - 10`

`5m = - 40`

`m = - 8`

6.

Multiplication Equality

Addition Equality

Division Equality

Check:

`( - 25r + 13)/(4) = - 3`

`- 25r + 13 = - 12`

`- 25r = - 25`

`r = 1`

8.

t=3,. Given

`3t = 9`

Justification: Multiply both sides by 3

Step 2:

`3t + 50 = 59`

Add 50 to both sides.

Step 3:

`(3t + 50)/(4) = (59)/(4)`

Divide both sides by 4.

Check

`(3t + 50)/(4) = (59)/(4)`

`3t + 50 = 59`

`3t = 9`

`t = 3`
