Answer:
7.14%
Step-by-step explanation:
The yearly earning of Mary = $28000
Per week earning = 28000 / 52 = $538.46
Subtract 538.46 from weekly gross amount.
= 658 - 538.46
= 119.54
Now find the percentage:
= 119.54 / 1673.19
= 0.0714
= or 7.14%
Answer:
x=2 y=-3
Step-by-step explanation:
We first need to isolate x to get x+2y=-4:x=-4-2y
-4-2y-2y=8
simplify:
-4-4y=8.
We can also do the same for y which is -4-4y=8:y=-3
for the x, we can now substitute it to give us:
x=-4-2(-3)
-4-2(-3)=2
x=2
So, our answers are x=2 and y=-3

400 miles per hour is a rate. For every hour, the airplane travels four hundred miles.
Knowing this, If the plane travels for three hours, we use a simple multiplication equation to represent this problem.
400 x 3 = 1200
The plane traveled 1200 miles, if it traveled at a speed of four hundred miles for three hours.
