Distribute the 8p to all of the numbers in the parenthesis. You would multiply the coefficient and add the exponents. The answer would be B.
Answer:
Step-by-step explanation:
We have the following variables:
y: hours of sleep
x: age
Each day, a young person should sleep 9 hours
This means that y is 9 added to something
plus 1 4 hour for each year that the person is under 18 years of age.
For each year the person is under 18 years of age, she should sleep 1/4 = 0.25h on top of the 9 hours.
So the equation relating hours of sleep y and age x is:
Answer:
$33.60
Step-by-step explanation:
multiply 40 by 0.20 = 8 subtract 8 from 40= 32 x 0.05 is 1.6 so its 33.6
Answer:
y = 5
Step-by-step explanation:
Subtract 2y from either side. It'll cancel out both of them. Then the equation is 8y = 40.
Divide both sides by 8 and you get y=5
Pretty sure that's right. I have a dad who has a math degree so I think it would be right because he helps me every time.
