Answer:

2 1/28

Step-by-step explanation:

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(3/4×7/7)+(9/7×4/4)=?

Complete the multiplication and the equation becomes

21/28+36/28=?

The two fractions now have like denominators so you can add the numerators.

Then:

21+36/28=57/28=2 1/28

Makayla is moving and must rent a truck. There is an initial charge of $40 for the rental plus a fee of $3 per mile driven. Writ
Sergeeva-Olga [200]

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)
