Answer:
use this equation: 150=1x+0.5y
Step-by-step explanation:
a) standard form equation above
b) 150=1x+0.5y
subtract 1x from both sides
then divide all by 0.5 to get slope intercept form
c) plug it in: 150=1(40)+0.5y and solve to get 220
d) take the y intercept from answer b. and the y intercept shows how many you have to sell of each to reach you $150(I think, this part might be wrong...idk)
Answer:
X= - 2
Step-by-step explanation:
-3 (5x+6) - 3x = 6-6x
Remove the parentheses
-15x-18-3x=6-6x
Collect the like terms
-18x-18=6-6x
Move the variable to the left-hand side and change its sign
18x+6x=6+18
Collect the like terms
-12x=24
Divide both sides
X=-2
Answer: 24 students
Explanation:
