Answer:
x=3, y=76
Step-by-step explanation:
You set them equal because you plug in "y" as 22x+10 into "y=20x+16"
22x+10=20x+16
2x=6
x=3
20(3)+16=76
Answer:
x = 4
Step-by-step explanation:
√x + 1 = 3
√x = 3 - 1
√x = 2
(√x)² = (2)²
x = 4
Answer:
The correct answer is 12 and a half or 13 weeks.
Step-by-step explanation:
First, convert the values to decimals.
27 1/2 = 27.5
2 1/4 = 2.25
Then, divide miles of road that need to be repaved by the number of miles that are repaved per week.
27.5/2.25 = 12.2222222222222
Round that up to 12 and a half weeks or 13 weeks.
Yeah there all right but I have a little hinch for the last and first one
