Answer: x = 3
Step-by-step explanation:
First you need to start by adding positive 4x to both sides since the 4x is a negative. 4x + (-7x) = -3x. Then it is just simply -3x+2 = -7. Since 2 is a positive number subtract both both sides by 2. Then you should get -3x = -9. Then divide both sides by -3 and the answer is x = 3.
Answer:
-3mn + 14n - m is your answer.
Step-by-step explanation:
Combine like terms (terms with the same amount of variables). Reorder so that it is so:
(-5mn + 2mn) + (6n + 8n) + (-4m + 3m)
Combine like terms. Add or subtract the variables. Note that if there is no number, it is assumed that there is a 1:
(-5mn + 2mn) = (2mn - 5mn) = -3mn
(6n + 8n) = 14n
(-4m + 3m) = 3m - 4m = -m
(-3mn) + (14n) + (-m)
-3mn + 14n - m is your answer.

Answer:
12
Step-by-step explanation:
15 feet total amount combined by pole and
birdhouse
4 foot tall person makes 5 feet long
shadow
5×3=15
4x3=12 so the birdhouse and pole are 12
feet
THANKS!
We simply substitute the values of x and check if the values of y match.
y(1) = 19,000
y(2) = 18,050
y(3) = 17,148
y(4) = 16,290
As is visible from the table, the first value quoted is incorrect.
