Answer:
y = -10
Step-by-step explanation:
Hey there!
To solve this you first have to distribute the -3 to y and 5. When you do this you get...
-3y - 15 = 15
Add 15 on both sides you get...
-3y = 30
Divide by -3 and you get...
y = -10

Answer: The answer is 2x + 7.
Explanation: First, we need to add the numbers:
9x + 3 – 7x + 4
9x + 7 - 7x
And finally, we combine like terms:
9x + 7 - 7x
2x + 7
Answer:
28 < x < 114
Step-by-step explanation:
- x cannot be larger than or even equal to 71 + 43 = 114. So it must be less than 114.
- But there are limits on the other end as well. 43 +x > 71, otherwise you won't have a triangle. so you have to solve that inequality as well
- 43 + x > 71 Subtract 43 from both sides.
- 43-43 + x > 71 - 43
- x > 28
- To put this in the form of the answer you need it looks like this.
- 28 < x < 114
Using a calculator divide 2x10^8 by 5x10^6 and you get 40 therefore it is 40 times larger
I think the answer is :
3x^2 + 2 - x
