The answer is (-1,-3) because the line passes through that point.
Answer:3/2
Step-by-step explanation:
6/10 ➗ 2/5
6/10 x 5/2
(6x5)/(10x2)
30/20=3/2
1 quart is equal to 4 cups, so you divide 12.70 by 4.

You can round that up to $3.18 for 1 cup of balsamic vinegar
Answer:
35
Step-by-step explanation:
276.5 / 7.9 X 10 = 2765 /79 = 35
4t+2c=200
2t+7c=400
I will solve for c in terms of t first
4t+2c=200
2c=200-4t
c=100-2t
Then I will substitute this in for c in the second equation to make it single variable
2t+7c=400
2t+7(100-2t)=400
2t+700-14t=400
300t=12
t=25
Tables cost $25 each
Plug t back into one of the ORIGINAL equations to find the cost of chairs
4(25)+2c=200
100+2c=200
2c=100
c=50
Chairs cost $50 each
Hope this helps! :)
