Answer:
Loaves of bread: b can't be a negative value, then the first table doesn't include viable solutions.
The number of loaves of bread must be a whole number, then the second table doesn't include viable solutions.
c=3.5b
if b=0→c=3.5(0)→c=0
If b=3→c=3.5(3)→c=10.5
If b=6→c=3.5(6)→c=21
If b=9→c=3.5(9)→c=31.5
The third table includes viable solutions
Answer:
375 bags
Step-by-step explanation:
900/2.4=375 bags
Step-by-step explanation:
the answer is on the photo above
175
You are adding 82 to 93
<span>7x-4y=-7
5x+y=22
multiply 4 on the 2nd equation
</span>20x+ 4y=88
now you have
7x -4y = -7
20x + 4y = 88
--------------------add
27x = 81
x = 3
7x-4y=-7
7(3)-4y=-7
-4y = -28
y = 7
answer (3, 7) is the solution
