Answer:
m=-2
Step-by-step explanation:
You have to put the equation into y=mx+b form
which would be y=-2x-2
First you would divide 2x+y by 2 so that x+y/2=-1
subtract x on both sides y/2=-x-1
multiply 2 to get y=2(-x-1) simplify y=-2x-2
m=-2
Answer:
52
Step-by-step explanation:
Let total plants = x
grape tomato: 1/5 of x=18; (1/5)*x=18; x=18*5=90
other plants other than grape tomatoes and cherry tomatoes = 90-18-20=52
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
