Answer:
<u>Please read the answers below.</u>
Step-by-step explanation:
A. Write an equation to represent each company's total charges for cleaning a certain number of loads of laundry.
Company A equation (using x as the variable for the total cost and y for the number of loads)
<u>x = 20y + 8</u>
Company B equation (using z as the variable for the total cost and y for the number of loads)
<u>z = 24y + 4</u>
B. Which company would charge less for 5 loads of laundry?
Company A
x = 20 * 5 + 8
<u>x = US$ 108</u>
Company B
z = 24 * 5 + 4
<u>z = US$ 124</u>
<u>Company A will charge US$ 108, US$ 16 less than Company B</u>
C, How much money is saved by using the services of Company A instead of Company B to clean 9 loads of laundry?
Company A
x = 20 * 9 + 8
<u>x = US$ 188</u>
Company B
z = 24 * 9 + 4
<u>z = US$ 220</u>
<u>Company A will charge US$ 188, US$ 32 less than Company B</u>
The number of apples is x, and the number of oranges is y.
"Mia needs to bring at least 25 pieces of fruit to the school picnic."
means that x+y≥25
"She was told to be sure to bring more than 10 apples."
means that x≥10
thus, the inequalities are:
i) x+y≥25
ii) x≥10
ANSWER
My answer is in the photo above
Answer:n > -5
Step-by-step explanation:
5n>-26+1 add 1 to both sides which cancels 1
5n>-25
Divide each term
5n/5 -25/5
n>-25/5
n>-5
