Mathematics

Elenna [48]3 years ago
4 0

Step-by-step explanation:

(7 + x) / 3 = 2x - 5

7 + x = 3(2x - 5) (multiply 3 on both sides)

7 + x = 6x - 15 (distributive property)

5x = 22 (arrange like terms)

x = 4.4 (divide 5 on both sides)

lakkis [162]

Answer:

<h2>x= -2</h2>

8x =  - 19 + 3 \\ 8x =  - 16

Divide both sides of the equation by 8

\frac{8x}{8}  =  \frac{ - 16}{8}

Simplify

x =  - 2

You work 4 hours on Saturday and 8 hours on Sunday. You also receive a $50 bonus. You earn $164. How much did you earn per hour?
Marina86 [1]
To find the hourly rate, we would first need to take the total earnings and subtract the bonus. $164 - $50 = 114 This gives us the total money earned for hourly work. Then we need to add the total hours worked: 4 + 8 = 12. Lastly, we need to take the total money earned and divide it by the total hours worked: 114 / 12 = 9.50 or $9.50 per hour. The equation could look like: 4h + 8h + $50 = $165
