Answer:
d = 3 c= 1/4
Step-by-step explanation:
Eq. 1) -4c + 5d = 14
Eq. 2) -4c + 3d = 8 ( the written Eq. says 40 but I am guessing it's 4c )
subtract Eq. 1 and Eq. 2
2d=6
d=3
plug 3 in for d in Eq. 1
-4c + 5(3) = 14
-4c + 15 = 14
-4c = -1
c = 1/4
You would have none left. If you started with one cup of cornmeal and then you used that one cup of cornmeal to make the muffins, you would have none left
1. t+b=280
2t+3b=660
b=-t+280
2t-3t+840=660
-t=-180
t=180
b=100
He sold 180 tacos and 100 burritos
2. x=5 cent pencils
y=10 cent pens
x+y=1000
.05x+.1y=74.5
y=-x+1000
.05x-.1x+100=74.5
-1.5x=-25.5
15x=255
x=17
y=983
They sold 17 pencils and 983 pens
