Answer:
The sides are 5,18,16
Step-by-step explanation:
To find the perimeter of a triangle, we add up all the sides
n +4n-2 + 5n-9 = 39
Combine like terms
10n -11 = 39
Add 11 to each side
10n-11+11 = 39+11
10n = 50
Divide by 10
10n/10 =50/10
n = 5
Now we need to find each side
n = 5
4n-2 = 4(5)-2 = 20-2 =18
5n-9 = 5(5) - =25-9 = 16
The sides are 5,18,16
Because they are congruent sides
Answer:
9 minutes
Step-by-step explanation:
To find how long it would take to read 6 pages, find the unit rate or the time to read 1 page.
Alejandro read 4 pages in 6 minutes. This means it takes him 6/4 = 1.5 minutes to read 1 page.
To read 6 pages it will take him 6*1.5 = 9 minutes.
