Answer:
His friend won 10 games.
Step-by-step explanation:
In order to find this, divide the number of games that he won by his part of the proportion (7).
35/7 = 5
5 in this case is the scale factor. We can now multiply his friend's winnings to get the total number of his wins.
5 * 2 = 10
You can rewrite the second equation because you know what y equals, so you can write it as 2x + x + 3 = 9
3x + 3 = 9
- 3
3x = 6
÷ 3
x = 2
And now you use the equation of what y equals and substitute in the value of x, so y = 2 + 3
y = 5
So your final answer is A. (2, 5). I hope this helps!
To find this answer, you must first find out how much each car makes them. You do 144 divided by 24 to do this. You get the answer 6. Which means that they make $6 for each car washed.
Now that you know how much each car wash makes them, you multiply 6 by 30 to get how much they earned on Sunday.
6 x 30= 180.
So, they earned B.$180 on Sunday
The answer would be A) $79.20
(220*.4).9 as 60 percent off means that the product is only 40 percent of its original value, furthermore, we multiply the entire thing by .9
