Answer:
15x because the air ballon drops 15 meters each time the elevation decreases
Step-by-step explanation: Im not sure if this is what youre looking for but it drops 15 meters each time, 5 times so the change would be 15x and the x is used as how mant different times the elevation drops
Did you mean -10? If so that is -1 and 10. 10 and 9 is not possible to answer.
-1+10=9
-1*10=-10

Answer:
(-3, 8) is the solution
Step-by-step explanation:
The LCD of the first equation is (3)(4) = 12. Rewriting this equation, we get:
4x + 3y = 12
to which we add the second equation, obtaining:
4x + 3y = 12
2x - 3y = -30
-------------------
6x = -18
Dividing both sides by 6 yields x = -3
Substituting -3 for x in the first equation yields 4(-3) + 3y = 12, or
-12 + 3y = 12
Then 3y = 24 and y must be 8.
The solution to this system of linear equations is (-3, 8).
You have a log that is 20 feet long, and you are breaking it into 2-foot long sections.
We are cutting it into 10 equal pieces, each piece is 2 feet long (20 feet ÷ 2 feet = 10 pieces)
I am going to make a diagram where an equal sign, =, is a piece of the tree, and a slash, /, is a cut.
If we look at this, there are 10 pieces, and 9 cuts.
"Bob can cut through a log in two minutes."
This means that each of the 9 cuts takes 2 minutes, 9×2=18
It will take Bob 18 minutes to cut up the log
