Answer:
20/3
Step-by-step
(base1+base2)/2 * height = area of a trapezoid
64/12=16/3
16/3*2 = 32/3
32/3-4 = 20/3
Answer: c = 8
Step-by-step explanation:
Simplifying
9c + -3c = 48
Combine like terms: 9c + -3c = 6c
6c = 48
Solving
6c = 48
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Divide each side by '6'.
c = 8
Simplifying
c = 8
300.84m^2
First, set up the equation
A=27.6•10.9
Next, multiply(use a calculator)
And you get the answer.
^2 means squared.
4 friends evenly dividing up a n - slice pizza
So each one get 
slices of pizza.
For example, if n = 12 slice then each friend gets 12/4 = 3 pieces. If Harris ate one slice less then he ate 
=3 -1 = 2 pieces.
So the general expression for slices of pizza did Harris eat is
Since the percent increase is bigger than 100%, it definitely has to be more than 54,000.
so let's break this down:
250%= 100% + 100% + 50%
we know 100% is the whole price so if there are 2 100% we have to multiply the price by two!!!
54,000•2 = 108,000
now, 50% is half of the whole price, divide the price by two:
54,000÷2= 27,000
so add your results and you will get this!
108,000+27,000= 135,000
