Answer: it will take them about 24 minutes working together
Step-by-step explanation:
1/40 + 1/60 =
6/240 + 4/240 = 10/240 = 1/24
1/24 = 1/t
Cross multiplication:
1*t = 1*24
t= 24
1800
LCM of 10 and 15 = 30
LCM of 6 and 20 = 60
30(60) = 1800
Answer:
x ≤ $12 a day
Step-by-step explanation:
5000-1400=3600
3600/300=12
Since we already know that the slope is 0, x cancels out in the equation.
y = mx + b → y = b
We just need to find the y-intercept. Using the coordinate (2, 4) we can substitute with y.
4 = b
Hence, the answer is b) y = 4

Answer:
Length = 18 Width = 11
Step-by-step explanation:
Perimeter = 2(length) + 2(width)
So let's label the unknown length as x. Width would then be (x-7). Then plug it into the perimeter equation.
2(x) + 2(x-7) = 58
Then use PEMDAS which will give us
2x+2x-14 = 58
Combine like terms
4x -14 = 58
Add 14 to both sides
4x = 72
To get x by itself you have to divide both sides by 4.
x = 18
So length is 18 and width is (18-7) which is 11.
