Allison is working two summer jobs, making $12 per hour lifeguarding and $8 per hour washing cars. Last week Allison worked 3 mo
timama [110]

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

x-y=3

<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

12x+8y=96

You get the system of two equations:

\left\{\begin{array}{l}x-y=3\\ \\12x+8y=96\end{array}\right.

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.

connor scored 14370 points in a game amy scored 1089 fewer points than connor. how many points did amy score
Dahasolnce [82]
So first you would have to do is read the problem carefully and understand what it's asking you and what I mean is look for some clues that would help you to solve the problem. For instance, the word fewer is a good word to help us because the word fewer means less or taking away and so what that tells us is, what we have to do is subtract 1089 points from 14370 points they want to know how many points did Amy scored and so in order to do that we need to subtract and so our final answer would be 13281 as our final answer and so thank you for this question and keep in mind that you always have to read the question carefully in order to understand. So Amy scored 13281 in the game. Have a blessed day.
