Answer:
5 hours
Step-by-step explanation:
We can write a ratio
20 laps 100 laps
-------------- = --------------
1 hour x hours
Using cross products
20x = 100
Divide by 20
20x/20 = 100/20
x = 5 hours
Solution:
<u>We know that:</u>
<em>Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.</em>
<u>Cancel out the "2" by dividing it by 18.</u>
<u>Simplify the multiplication.</u>
Answer:
13
Step-by-step explanation:
Not sure, i'm sorry
should be the same logic as
a=b
b=c
a=c
If x is negative, then 10-x must be positive.
for example: let's say x=-1. then 10-(-1)=11
Answer:
the real solutions are the ones that actually cross the x-axis.
so the real solutions are (-5, 0) (-1,0) (4,0) and (8,0)
