Answer:
150 seeds sprouted
Step-by-step explanation:
First divide 270/9, you will get your rate for 1/9th
Then multiply by 5
The possible side length combinations would be 1 and 39 or 3 and 13.
1 and 39: the perimeter of these two would be 80.
3 and 13: the perimeter of these two would be 32.
The answer is 32.
10(2x)+x
21x is the original number
12x is the reversed number
24x is the reversed then doubled number
Set up an equation:
24x=21x+9
3x=9
x=3
The original number is 63 and the reversed number is 36, which then is 72 when doubled.
Answer:
A) The cost is the same at 5 months.
Step-by-step explanation:
Lets use m to represent the number of months it will take for the cost to be the same. If we set up an equation, we can write:
75 + 10m = 50 + 15m
-50 on both sides
25 + 10m = 15m
-10m on both sides
25 = 5m
Divide by 5 on both sides.
5 = m
That means it will take 5 months for the costs to be the same.
