Answer:
38.65*.20=7.73
38.65+7.73=46.38
So the total bill is $46.38.
100-46.38=53.62
So she’ll receive $53.62 in change.
Step-by-step explanation:
A tennis court is a rectange.
The area of a rectange is equal to length * width.
A = l*w
2808 = l * 36 (Divide both sides of the equation by 36)
L = 78
Answer:
x = 4
Step-by-step explanation:
2x - y = 11
X + 3y = -5
Multiply the first equation by 3
3(2x - y )= 11*3
6x - 3y = 33
Add this to the second equation to eliminate y
6x - 3y = 33
X + 3y = -5
--------------------
7x = 28
Divide by 7
7x/7 = 28/7
x = 4
4n - 6m = -2
Let n = -2
4(-2) - 6m = -2
-8 - 6m = -2
-6m = -2 +8
-6m = 6
m = 6/-6
m = -1
So, when n is -2, m is -1.
Now, do the same when n is -1 and again when n is 0.
