Answer:
A. x=2, y = 7.
B. (2, 7).
Step-by-step explanation:
A. You can eliminate y by subtracting the equations:
y = 8x - 9
y = 4x - 1 Subtract:
0 = 4x - 8
4x = 8
x = 8/4 = 2.
Now substitute for x in the first equation:
y = 8(2) - 9 = 7.
Check in the second equation:
y = 4x - 1
7 = 4(2) - 1 = 7. Check is OK.
B. On the graph they will intersect at the point (2, 7).
They will intersect here because the values x=2 and y=7 satisfy both the 2 equations.

Answer:
29 2/5
Step-by-step explanation:
We know that 5 fifths make up a whole. The chef only needs 3/5 of that whole, so we still have 2 fifths remaining. Now, we have to subtract 50 by the number of lunch orders, 20. 50 subtracted by 20 is equal to 30, but we have to subtract a whole because of the fraction. We get the number 29. Then, we add the remaining fraction back. We get the answer as 29 2/5.
Best of Luck!
