-3x-3 = 4x-3
-3 = 7x-3
0 = 7x
x = 0
Answer:
5x + 17
Step-by-step explanation:
To answer this question, we must first simplify:
2 (x + 7) + 3 (x + 1) = 2x + 14 + 3x + 3
Then, we have to combine like terms:
2x + 14 + 3x + 3 = 5x + 17
And there is our answer, 5x + 17

Answer:
7:13
Step-by-step explanation:
There are 14 girls and 12 boys, so there are 26 students in total. Since we are looking for the ratio of girls to students, the ratio will be 14:26. To simplify it, we will divide 14 and 26 by their greatest common factor: 2. We will get the ratio of 7:13.

Answer:
Volume of rectangular prism:
V1 = base x height = 4 x 6 x 12 = 288 ft3
Volume of triangular prism:
V2 = base x height = 4 x (6/2) x 6 = 72 ft3
Volume of composite prism:
V= V1 + V2 = 288 + 72 = 360 ft3

Answer:
x = 6
Step-by-step explanation:
<u>Step 1: Distribute
</u>
2(3x + 2) = 2x + 28
(2 * 3x) + (2 * 2) = 2x + 28
(6x) + (4) = 2x + 28
<u>Step 2: Subtract 2x from both sides
</u>
6x + 4 - 2x = 2x + 28 - 2x
4x + 4 = 28
<u>Step 3: Subtract 4 from both sides
</u>
4x + 4 - 4 = 28 - 4
4x = 24
<u>Step 4: Divide both sides by 4
</u>
4x / 4 = 24 / 4
<em>x = 6
</em>
Answer: x = 6
