P+(2p-250)=2858 where p equals East High School's population
simplify (combine like terms)
3p-250=2858
add 250 to each side of the equation
3p=3108
divide each side by 3
p=1036
1036 students attend East High School.
Answer:
$6.88
Step-by-step explanation:
We are trying to compare two options: Buying a magazine for 12 months or for just 1 year.
To solve this, we can multiply the monthly rate by 12 because there are 12 months in a year.
5.99 x 12 = 71.88
The other option is to just pay $65 dollars for a whole year (12 months).
Comparing the two options, we see paying for the whole year is cheaper than paying for each month individually. Because of this, we can subtract $65, the cheaper option, from $71.88 to get $6.88
Chris will save $6.88 by paying for the whole year instead of purchasing for each month.
Answer:
Length in feet is equal to
, where P is the perimeter
Step-by-step explanation:
Let the width (W) of the yard be "X"

Then the length(L) of the yard will be


The perimeter of the yard will be equal to the sum of twice the length and width of the yard
Thus,

Substituting the given values in above equation, we get -

Thus, width in terms of perimeter is equal to

Length in feet is equal to 
Answer:
60
Step-by-step explanation:
All angles = 180
All sides are equal
Therefore, 180/3 = angle degrees = 60
x is an opposite angle of bottom right angle therfore x = 60
