Answer:
5
Step-by-step explanation:
20% of p = 10
20% = 0.2
Multiply
0.2p = 10
Multiply both sides of the equation by 5
p = 50
Find 10% of p
10% = 0.1
Multiply
0.1(50)
5
10% of p is 5

We Know, speed = Distance / Time
Here, Distance = 2748 miles
Time = 6 hours
Substitute their values in to the expression,
Speed = 2748 / 6 = 458 Miles / Hour
So, the speed would be: 458 miles/hour

We know that the formula for the area of a rectangle is:
We know that the area is 165. Now we need to solve for the dimensions.
Let the width of the rectangle be "

"
Then the length of the rectangle is
Substitute.
Multiply the terms.
Bring the 156 over.
We have to use the quadratic formula to solve this now. Let us restate it:

Now I'm going to fast forward this because all the rest is boring stuff and substitution. The answer is:

Since we cannot have a negative answer, we must cancel out the other answer, which I did not include.
Hope this helped! :)

Answer:
2 6/10 or 13 / 5 = 2.60000
Step-by-step explanation:
33
Simplify ——

Adding fractions that have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
59 - (33) 13
———— = ——
10 5
