Answer:
Step-by-step explanation:
Perimeter of a triangle equals side 1 plus side 2 plus side 2
P = s1 + s2 + s3 side 1 = side 2 = x
x/side 3 = 5 / 3
x = (5/3) side 3
x (3/5) = side 3
perimeter = 65 slove for x
65 = x + x + 3x/5
325 = 5x + 5x + 3x
325 = 13X
25 = x equal side 1 and side 2
side 3 = 25(3/5) = 15
9/10. make the bottom numbers the same to add fractions. you can do that by multiplying 7/10 by 10/10.
70/100 + 20/100 = 90/100
90/100 = 9/10
you can also reduce 20/100 to 2/10.
7/10 + 2/10 = 9/10

Answer:
2x+5y
Step-by-step explanation:
5x + 5y - 3x
=2x+5y
Answer:
y≤5
Step-by-step explanation:
3 ≥ y - 2
Add 2 to both sides
3 (+2) ≥ y - 2 (+2)
5 ≥ y
or
y ≤ 5
Hope this helps!
