Answer:
Simplifying
2(x + 3) + 3x + -10 = 0
Reorder the terms:
2(3 + x) + 3x + -10 = 0
(3 * 2 + x * 2) + 3x + -10 = 0
(6 + 2x) + 3x + -10 = 0
Reorder the terms:
6 + -10 + 2x + 3x = 0
Combine like terms: 6 + -10 = -4
-4 + 2x + 3x = 0
Combine like terms: 2x + 3x = 5x
-4 + 5x = 0
Solving
-4 + 5x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 5x = 0 + 4
Combine like terms: -4 + 4 = 0
0 + 5x = 0 + 4
5x = 0 + 4
Combine like terms: 0 + 4 = 4
5x = 4
Divide each side by '5'.
x = 0.8
Simplifying
x = 0.8

Answer:
84
Step-by-step explanation:
Well lets begin by noting that 30% are Grade Eight. That means that 70% will be Grade Six and Seven, but thats not the question, the question is how many people are sixth and seventh grade. As I said before the answer is 84. To find 10% of 120, you shift the decimal point one place to the left and get 12. I earlier said 70% are grade six and seven meaning 70/10=7
All thats left is a simple multiplication problem, 12x7 which gives you 84. To ensure you are correct. 84/7=12 and that promises you a correct answer.
If you do not understand the math I did here reply and I will further explain. For now I hope this helps!
