Answer:
5 felt pads.
7 cards.
Step-by-step explanation:
Remark
- The total number of items is 12
- So let the felt sheets be x
- Let the cards = y
Equations and Solution
x + y = 12
Now the price is 7.75 that she has to pay for the 12 items. She wants to come back with 0 dollars.
0.5x + 0.75y = 7.75 Multiply this equation by 2
x + 1.5y = 15.50 write the first equation underneath and subtract.
<u>x + y = 12</u>
.5y = 3 Divide by 0.5
y = 3/0.5
y = 7
So she can get 7 cards.
x + y = 12
x + 7 = 12
x = 12 - 7
x = 5
So she can buy 5 felt pads.
Answer:
(((x-4)/2)^3)+3=y
Step-by-step explanation:
You just have to switch the y and the x and then isolate the y
You can graph it but cant answer it because there is two variables so try and change it to slope intercept form do you know how ???????
The answer is X=4.
It is both parallel to x=-3 and passes through (4,2)
What that is exactly??? I want to help but I can’t! Tell me tell me
