Answer:
Allison worked 6 hours lifeguarding and 3 hours washing cars.
Step-by-step explanation:
Let
Number of hours Allison worked lifeguarding last week = x
Number of hours Allison worked washing cars last week = y
1. Last week Allison worked 3 more hours lifeguarding than hours washing cars hours, then
<u>Lifeguarding:</u>
$12 per hour
$12x in x hours.
<u>Washing cars:</u>
$8 pere hour
$8y in y hours.
2. Allison earned a total of $96, hence
You get the system of two equations:
Plot the graphs of these two equations (see attached diagram). These line intersect at point (6,3), so Allison worked 6 hours lifeguarding and 3 hours washing cars.
Answer:
d. m+ 3 = 15
Step-by-step explanation:
it explains you have to add m to 3 so it can't be m + 15. also, its says equals to 15 so 15 will be after the equal sign.
hope this helped... branliest please :)
Answer:
-2
Step-by-step explanation:
m = 5-(-3) / -2-2
m = 5+3/-4
m = 8/-4
m = 2/-1
m = -2
Answer:
Which of the following are possible rational roots of the polynomial function? Check all that apply. F(x) = 5 x2-3x+3
A. ±3
B. ±1
<em><u>C. ±1/3</u></em>
D. ±5
E. ±1/5
Answer:
8
Step-by-step explanation:
We have, 25% × x = 200
or,
25
100
× x = 200
Multiplying both sides by 100 and dividing both sides by 25,
we have x = 200 ×
100
25
x = 800
If you are using a calculator, simply enter 200×100÷25, which will give you the answer.
So now that you have the original number you just need to find 1% of 800
1% of 800 is 8
