Answer:

Explanation:

1.


\displaystyle\\(1)/(5)x+15=-5 \\\\(1)/(5)x+15-15=-5-15\\\\(1)/(5)x=-20

Multiply both parts of the equation by 5:


x=-100

2.


4-3x=5\\\\4-3x-4=5-4\\\\-3x=1

Divide both parts of the equation by (-3):


\displaystyle\\x=-(1)/(3)

3.


(3x)^0+(8x+70)^0=180^0\\\\(3x)^0+(8x)^0+70^0=180^0\\\\(11x)^0+70^0-70^0=180^0-70^0\\\\(11x)^0=110^0

Divide both parts of the equation by 11:


x=10


m\angle TRS=(8(10)+70)^0\\\\m\angle TRS=(80+70)^0\\\\m\angle TRS=150^0

4.


\$ 25(5)+\$250=\\\\\$125+\$250=\\\\\$375

5.


\displaystyle\\(x)/(15)=(30)/(18)

Multiply both parts of the equation by 15:


\displaystyle\\x=(30(15))/(18) \\\\x=(450)/(18)\\\\x=25
