<h3>Answer:  B. 6</h3>

Explanation:

The triangles are similar. We can use the SAS similarity theorem to prove that claim.

Because the triangles are similar, the corresponding sides form a proportion like shown below

12/8 = 9/x

12x = 8*9 ... cross multiply

12x = 72

x = 72/12

x = 6 which is why the answer is choice B

natita [175]
The answer is $.085. This is the cost of the gasoline per mile. I got the answer through adding all the expenses (insurance, registration, and maintenance) which added up to $1191 and then subtracting it from $1837, which gets me $646. Lastly, I computed for the cost of gasoline per mile through dividing $646 by 7600 miles. I got .085.

What is the coefficient of q in the sum of (2/3q-3/4) and(-1/6q-r)?
Harlamova29_29 [7]

Answer:

The coefficient is \frac{1}{2}

Step-by-step explanation:

The given sum is

(\frac{2}{3}q -\frac{3}{4})+(-\frac{1}{6}q-r)

We can choose to add only the coeffients of q or simplify the whole sum.

=\frac{2}{3}q -\frac{1}{6}q-\frac{3}{4})-r)

We collect the LCM for the q terms;

=\frac{4-1}{6}q-\frac{3}{4})-r)

This will give us;

=\frac{3}{6}q-\frac{3}{4})-r)

Which is the same as

=\frac{1}{2}q-r-\frac{3}{4}

The coefficient is \frac{1}{2}
