A number can be represented by n. So n/15≤450 then multiply both sides by 15 to get n by itself n≤6,750
Hope this helped!!! :)
C. 110. This is because all triangles add up to equal 180*. So you add the two angles you have and subtract from 180.
B+c+(c-b)+(b-c). That is your expression. b 11 c 16
First, let's convert the variables to real numbers: 11+16+(16-11)+(11-16)
Now, let's solve that equation. 11+16+5+(-5)
5+(-5) cancels out, so all we have left is: 27
That is your perimeter.
The other factor is (y - 3). If you multiply the two terms together, you will end up with
:
Answer:
3 hours
Step-by-step explanation:
Recall:
Distance = speed x time
we are given that speed = 18 km/h and distance = 54 km.
hence,
54 = 18 x time (divide both sides by 18 and rearrange)
time = 54/18 = 3 hours
