The length of each side of an equilateral triangle is increased by 5 inches , so the perimeter is now 60 inches . Write and solv
e an equation to find the original length of each side of the equilateral triangle
1 answer:
Answer:
15 inches
Step-by-step explanation:
Call the original side length x
This makes the new length x+5
The perimeter is the sum of the length of the sides. So for the new shape this is 3(x+5)=60
This can be solved in the following way:
x+5=20
x=15
So the original side lengths were 15 inches.

B. 55 seconds
The average equals the sum of all the numbers then divided by the amount of numbers added.
51+53+55+56+60=275
275/5=55 seconds
6+8+5=19
Probability= 8/19=0.42= 42% of picking green.
Remove 10 quarts from blue
5 parts blue 3 parts yellow
5 parts blue 3 parts yellow
5 parts blue 3 parts yellos
total: 15 parts blue
9 parts yellow
remove the remaining 10 parts blue, since you do not have any more yellow
When you multiply it is just 5*23=115
115*2= 230
