Anarel [89]

Answer:

2709 bricks.

Step-by-step explanation:

We have been given that Mr. Thomas delivers the same number of bricks with each delivery. The builder has ordered 3096 bricks and it will take 8 trips to deliver all the bricks.

First of all we will find the number of bricks delivered in one trip by dividing 3096 by 8.

$\text{Number of bricks delivered in one trip}=\frac{3096}{8}$

$\text{Number of bricks delivered in one trip}=387$

Now let us multiply number of bricks delivered in one trip by 7 to find the number of bricks delivered in 7 trips.

$\text{Number of bricks delivered in 7 trips}=387\times 7$

$\text{Number of bricks delivered in 7 trips}=2709$

Therefore, Mr. Thomas will have delivered 2709 bricks after 7 trips.

A class has 12 boys and 18 girls. the class as a whole has a gpa (grade point average) of 2.88, and the boys have a gpa of 2.52.

MrRissso [65]

<span>3.12 First, write an equation to express what you know. g = number of girls b = number of boys b * 2.52 + g * x = 2.88(b+g) Solve for x, first substitute known values for g and b 12 * 2.52 + 18 * x = 2.88(12+18) Add and multiply what you already know 30.24 + 18x = 86.4 Subtract 30.24 from both sides 18x = 56.16 Divide both sides by 18 x = 3.12 Therefore the GPA of the girls is 3.12</span>
