What is the formula for elimintation
inysia [295]

Answer:

The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

For one child, a childcare facility charges $350 per month for preschool and $5.00 per hour for each additional hour for after-s
Hatshy [7]

Answer:

D. 80

Step-by-step explanation:

We have the following function  :

f(h)=350+5h (I)

Where f(h) is the monthly fee for after - school care and preschool.

Where h represents the number of hours spent in after - school care.

We know that the total monthly bill for one child was $750 ⇒

f(h)=750

Using (I) we will find the value of the hours ''h'' that verifies the expression ⇒

f(h)=750=350+5h ⇒

750=350+5h\\750-350=5h\\400=5h\\h=\frac{400}{5}=80

We find that the value of the hours ''h'' is 80 hours.

The total number of hours the child spent in after - school care is D. 80
