Answer:
b = -17
Step-by-step explanation:
-2b - 12 = 22
+12 +12
-2b = 34
-2b/-2 34/-2
b = -17
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
The answer would be 4 1/4 (4.25)
10-1.5=8.5/2=4.25
Hope this helps!
