Answer:
-40% change
Step-by-step explanation:
- This change is a decrease, so first you need to find the difference between the two numbers--> 125 - 75 = 50
- Next, you divide by the original number, so 50 ÷ 125 = 0.4
- Finally, you multiply your answer by 100, so 0.4 x 100 = 40%. Because this is a decreasing change, you add a negative sign.

<em>Hello There. Here is Explanation How to get the answer.</em>
Explanation: x + y = -6 �> x = -6-y
xy = 8
(-6-y)y = 8
-6y - y^2 = 8
y^2+6y+8 = 0
(y+2)(y+4) = 0

Answer:
Step-by-step explanation:
The answer is 0.
Plug in 2 wherever there is an x.
Answer:
For 3x + 5y = -13 the answer is x= -13/3 + 5y/3
and for 2x + 15y=3 the answer x= 1.5 + (-15y/2)
Step-by-step:
For 3x+5y=-13 you have to add 5y on both sides. Then you have to divide by 3 on both sides and cancel out the common factor of 3. Then you would get x= 13/3 + 5y/3.
For 2x + 15y=3 you have to subtract 15y on both sides of the equation. You should have 2x=3 + (-15y). Then divide by 2 on both sides. 3 divided by 2 is 1.5 and -15y divided by 2 is -15y/2 since 2 doesn't have the same variable. so the answer should be x= 1.5 + (-15y/2).
