Answer:
22.5
Step-by-step explanation:
you have to do opposite bedmass to isolate the variable. the opposite of multiplying is division.
<u>(X+2)2</u> <u>=49</u>
2 2
Then do addition as subtraction.
X+2= 24.5
-2 -2
X= 22.5
First you have to figure out how much a video game costs and how much a used one costs
Then you plug in the costs of the video games into Janets equation 120=3x+y
(x= video games and y=used video games)
Then you subtract the cost of video games from 120 and then divide that answer by the cost of used video games and that should give you how many used video games she can get
You just need to rearrange it to find out the answer.
12p = 8
p = 8 ÷ 12
P = 0.67 or 2/3 (two thirds)
Use the law of cosines to find the missing length, which we'll call
when point a has an x value of 20(time) it has a y value of 10(# of cars) so after 20 mins 10 cars were washed which can be represented by (20,10)
