Answer:
Type A
Explanation:
Gasoline used <u>Per</u> mile
Type 1 ⇒ 106/5 = 21.2
Type 2 ⇒ 204/10 = 20.4
Type 3 ⇒ 298/15 = 19.9
Type 4 ⇒ 392/20 = 19.6
Notice that Type 1 is using less gasoline while travelling farther miles. Hence, Type 1 is the answer.
Susan goes 7.5 miles per hour.
Bethany goes 5 miles per hour.
Susan is faster.
1320 ways
This can be solved using something called permutation. There are 12 possible swimmers that can be in first place. After that, 11 swimmers left to be in second place. Finally there are 10 swimmers left for third place. Multiply these together you get 12•11•10=1320. Hope this helps!!
Answer: x = -1/2y + 2
Step-by-step explanation:
12x + 6y = 24 To solve for x first start by subtracting 6y from both sides
- 6y -6y
12x = 24 - 6y Now divide each side by 12
x= 2 - 1/2y
the 2 negatives get rid of eachother so its 2
2
