in one baseball season, peter hit twice the difference of the number of home runs alice hit and 3. altogether, they hit 9 home runs. how many home runs did each player hit that season? let h represent alice's home runs.
Answers
Answer:
- Alice 5
- Peter 4
Step-by-step explanation:
We're told to use h for Alice's homers. Then Peter's homers were ...
2(h -3) . . . . twice the difference of Alice's and 3
Then the total is ...
9 = h + 2(h -3) = 3h -6
15 = 3h
5 = h
Alice hit 5 homers; Peter hit 4.

2) n-10+9n-3
3) -4x-10x
4) -r-10r
Answers
1) 12r - 8 - 12
Here the like terms are -8 and 12.
-8 - 12 = -20
12r - 20
2) n - 10 + 9n - 3
Here the like terms are n and 9n and -10 and -3.
To make it easier you can reorder the expression to be n + 9n - 10 - 3.
n + 9n = (1 + 9)n = 10n
-10 - 3 = -13
10n - 13
3) -4x - 10x
Here the like terms are the only two terms in the expression, -4x and -10x.
(-4 - 10)x = -14x
-14x
4) -r - 10r
Here the like terms are the only two terms in the expression, -r and -10r.
(-1 - 10)r = -11
-11r
