Question

Check my work pls im failing math and this paper needs to be right

Answer 1

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`
