The formula to find the area of a rectangle is:
Length x Width
Answer:
x=72
y=54
Step-by-step explanation:
1st question. y=54 because it is a bisector of the 108 degree angles. (a polygon's interior angles add to number of sides minus 2 times 180)
There are two ys, so they add up to 108. A triangle's interior angles add to 180. 180-108 =72 x=72
2nd question, x is 72 ( it says x is the same measure) so 180-72=2y.
y still equals 54
Answer:
if you are trying to find the amount of gallons of gas she bought, the answer is 13.
Step-by-step explanation:
Change the equation, x - y = -3, to isolate x or y and plug that new equation into the equation 2x + 3y = 4
I changed it to: x = y - 3
so
2(y - 3) + 3y = 4
2y - 6 + 3y = 4
5y - 6 = 4
5y = 4 + 6
5y = 10
y = 10/5
y = 2
then you plug that 2 into the equation x = y - 3 to get the value of x
x = (2) - 3
x = -1
you can check this by plugging the x and y values into the equation 2x + 3y = 4
2(-1) + 3(2) = 4
-2 + 6 = 4
4 = 4
hope this helps :)
<u>Answer:</u>
$142500
<u>Step-by-step explanation:</u>
We are given that the resident of a certain University receives a salary that is three times the salary of one of the department heads.
Assuming
to be the salary of the department head, if the total of the two salaries is $190000, we are to find the salary of the president of the University.
We can write an equation in terms of
:



Salary of the president of the University =
= $142500
