Answer:
4.5 hours
Step-by-step explanation:
let t be the time elapsed
Therefore, we can set up a system of equations and solve accordingly
2t + 16.5 = 4t + 7.5
2t = 9
t = 4.5 hours more till they paint the same amount in square feet
The slope is -1/2. I know this because slope intercept of a line is y = mx + b. In the equation, y = -1/2 + 1/4, the slope is -1/2 and the y intercept is 1/4.
m stands for slope
b stands for y intercept
Yes, i believe so because u can count back twice and u will get 5. You could al so do: 7-2=5. Hope this helps
I'm not familiar with the notation but I'll guess this refers to the equation:
is -30 degrees
Choice b
Answer:
D
Step-by-step explanation:
The length of the rectangle is 6 inches shorter than the length of s, while the width of the rectangle is 1 inch longer than the length of s
Length of rectangle = s -6
Width of rectangle = s + 1
P rectangle = 2L + 2W or 2(L+W)
=> 2((s-6)+(s+1))
=> 2(2s-5)
=> 4s - 10
