V=29,564-532t would be the equation for that scenario
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
6.02 in long. First you need to find 6/14 then you multiply that answer by 14
Answer: 12 tablespoons (12/16 cup = 3/4 cup), 1/4 cup x 3 ( 3/4 = 3/4 cup), 1/8 cup x 6 (6/8 = 3/4 cup)
