Answer:
75 minutes
Step-by-step explanation:
if it takes 30 minutes to paint 2/5 of the room, then it must take 15 minutes to paint 1/5 of the room.
15 * 5 = 75 minutes or 5/4 hours

Answer:
Equation: y = 2x + 7
Step-by-step explanation:
If the line is parallel to the line resembling the equation y = 2x - 4, it would mean that the line would have a similar slope, leading to part of the equation:
y = 2x
Now substitute the x-coordinate -2 and y-coordinate 3 into the equation * (derived from (-2, 3) ):
3 = 2(-2)
Now simplify either side:
3 = -4
For 3 to equal -4, you would have to add 7:
3 = -4 + 7 = 3
This means the final equation is:
y = 2x + 7
(Sorry if this isn't the way you expected to solve the question)
Equation 1) 3x = 9 - 6y
Equation 2) 3x + 8y = 9
Add 6y to both sides in equation #1.
1) 3x + 6y = 9
2) 3x + 8y = 9
Subtract equations from one another.
-2y = 0
Divide both sides by -2.
y = 0
Plug in 0 for y in the first equation.
3x = 9 - 6y
3x = 9 - 6(0)
Simplify.
3x = 9 - 0
Simplify.
3x = 9
Divide both sides by 3.
x = 3
So, x = 3, y = 0
