Answer:
x = 4
Step-by-step explanation:
3x - 10 = 2 | Given
3x = 12 | Add 10 to both sides to isolate 3x
x = 4 | Divide both sides by 3 to get the value of x
Answer:
-6x² + 5x + 15
Step-by-step explanation:
Combine like terms. Like terms are terms with the same amount of variables.
Reorder based on descending powers:
-5x² - x² + 7x - 2x + 10 + 5
(-5x² - x²) + (7x - 2x) + (10 + 5)
(-6x²) + (5x) + (15)
-6x² + 5x + 15 is your answer.

Answer:
1/5 = q/p, or q:p
Step-by-step explanation:
You might want to rewrite 1/2p=2 1/2q as (1/2)p = (2 1/2)q.
To remove the fractions, multiply both sides by 2:
p = 2(2 1/2)q becomes p = 5q.
Dividing both sides by 5 yields p/5 = q.
Dividing both sides by p yields 1/5 = q/p, or q:p
