Can you retype this? It's kind of hard to understand what you are saying
11km = 5h
1km = 5h divide by 11km = 0.45h
16.5km = 0.45 x 16.5 = 7.42 h
Answer:
the last one
Step-by-step explanation:
.................
Only the second one
when diameter is 4 r=2
so 2pi*2=2²*pi the first is circumference the second area
2x + 3y + 2(x - y) - 3x
First you apply the distributive property:
2x +3y + 2(x) - 2(y) - 3x
2x + 3y +2x - 2y - 3x
The you combine like terms:
2x + 2x - 3x +3y - 2y
4x - 3x + y
x (x could also be 1x) + y (y could also be 1y)
The answer is x + y or 1x + 1y
