Answer:
- Burgers - $8.29 and fries - $4.39
Step-by-step explanation:
<u>Let burgers - b, fries - f</u>
- 8b + 3f = 79.49
- 12b + 6f = 125.82
<u>Double the first equation and subtract the second equation:</u>
- 16b + 6f - 12b - 6f = 2(79.49) - 125.82
- 4b = 33.16
- b = 33.16/4
- b = 8.29
<u>Find f:</u>
- 8(8.29) + 3f = 79.49
- 3f = 79.49 - 66.32
- 3f = 13.17
- f = 13.17/3
- f = 4.39
Yes good job!! the one you picked is correct
Answer:
2. for the first equation, it works, for the second it doesnt so the answer is no
i cant graph for you, but its easy, just use y=mx+b m being the slope which is rise over run
8. x=6, y=-1
10. x=-5 y=5
this is all i could do in such a short notice, but i hope it helped you!
Step-by-step explanation:
for 8, 
for 10,
Answer: Yes
Step-by-step explanation:
Imagine you have b = 2.
Plug 2 into the equation 2b + b = 3b
You get: 2(2) + 2 = 3(2)
Which solves to be 6 = 6
As long as the variable is the same, in this case b, and they are to the same power, in this case ^1, you can combine them.
.25=25/100=1/4

1/4 x 12=3
And three inches.
Hope this helps :)
