Answer:
C(m) = $(40+3m)
Step-by-step explanation:
In this question, we are asked to write an equation representing the total cost of renting a truck by Makayla.
We proceed as follows;
Form the question, we can deduce that there is an initial cost of $40 and a rental fee of $3 per mile driven.
Now, we were made to know that she had driven m miles. We now calculate the rental fee for this m miles she has driven. Mathematically, we only need to find the product here. The rental fees for the m Miles traveled would be m * 3 = $3m
Now the total cost C(m) would be = $40 + $3m or simply C(m) = $(40+3m)
Answer:
32.4
32.4 is 45% of 72
Step-by-step explanation:
Solution:
What is 45% of 72?
Y is 45% of 72
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 45% * 72
Converting percent to decimal:
p = 45%/100 = 0.45
Y = 0.45 * 72
Y = 32.4
Answer:
B. 8x^2-6x-7
Step-by-step explanation:
All you have to do is combine the like terms.
Like terms are the terms that have the same variable and same exponent.
The like terms in this equation are 6x^2 and 2x^2, 11x and -17x, and -3 and -4.
When you add 6x^2 and 2x^2, you get 8x^2
When you add 11x and -17x, you get -6x
When you add -3 and -4, you get -7.
Putting these all in order, your answer is
8x^2 - 6x - 7
