How many hours a week do you have to work to make $5000 a month?
nasty-shy [4]
It depends on how much you earn in an hour .. so for example if your earn 100$ in 1 hour so you need to work for 50 hours in total because 5000 divided the amount of money you make in a single hour which is 100 in this example will be 50 hours in total .. to get the amount of hours you need to work a week you should know that the month has 4 weeks .. so 50 divided 4 equals 12.5 hours

Can someone help me please
Schach [20]

Answer:

Step-by-step explanation:

The system of equations is expressed as

y=-2x+7 - - - - - - - - 1

y=5x-7 - - - - - - - - -2

We would equate equation 1 and equation 2. It becomes

- 2x + 7 = 5x - 7

We would add 2x to the left hand side and the right hand side of the equation. Also add 7 to the left hand side and the right hand side of the equation. It becomes

- 2x + 2x + 7 + 7 = 5x + 2x - 7 + 7

14 = 7x

Dividing the left hand side and the right hand side of the equation by 7, it becomes

7x/7 = 14/2

x = 2

y= -2 × 2 + 7

y = - 4 + 7

y = 3
