Part A
So the coefficient would be the number that is with a variable. The coefficient of 7.50h is 7.50. The variable is h, variables can be a letter or symbol that stands for something in a equation. For this question, h stands for the number of hours Corinne works. The constant is the number that is alone in the equation. That doesn't have a variable with it. In this equation the constant would be the number 40.
Part B
To solve this I will plug in 25 into "h" in and 300 for "s" in the equation 7.50h + 0.20s + 40 and then solve.
1. 25 * 7.50 = $187.5.
2. 0.20 * 300 = $60
3. Add it all together: $187.50 + $60 = $247.50 + $40 = $287.50
Part C
If Corrine gets a raise and earns $9 an hour the coefficient would change. It would be 9h instead of 7.50h.
Let’s condense the original expression and see if that’s one of the answers
-1/2(-3/2 x + 6x + 1) - 3x
First we distribute the -1/2
((-1/2)(-3/2 x) + (-1/2)(6x) + (-1/2)(1)) -3x
3/4x - 3x - 1/2 -3x
Combine like terms
(3/4 x - 3x - 3x) -1/2
-21/4 x - 1/2
We could make this a mixed number
-5 1/4 x - 1/2
(Mixed number: 5 times 4 plus one gets the numerator)
So the answer is D
Hello!
You use the Pythagorean theorem to solve this
Put in the values it tells you to
Square the numbers
Subtract 19.36 from both sides
Take the square root of both sides
a = 3.3
The answer is 3.3
Hope this helps!
Answer:
220
Step-by-step explanation:
plug it into surface area formula for rectangular prisms
A=2(wl+hl+hw)
3/4
when it’s parallel it has the same slope!
