Answer:
12 hours :)
Step-by-step explanation:

Infinite solutions. This equality is true for any value of n.
a.
Simple, first we add the numbers up. 3+3+3+3=12, you asked what is the probability that it is a bag of peanuts, their are 3 bags of peanuts. Let's make a fraction. The fraction is going to be 3/12, we can simplify 3/12 into 1/4. So, the answer is A. 1/4
Long piece: 5x + 3
Short piece: x
Long + Short = Total
5x + 3 + x = 45
6x + 3 = 45
6x = 42
x = 7
Long piece: 5x + 3 = 5(7) + 3 = 35 + 3 = 38
Answer: short = 7 ft, long = 38 ft
The correct answer shall be B.
by arranging into the form y=mx+c, we get m=2.5 and c= -3, where m is slope and c is the y intercept.
Hope it helps☺
