5 is b because 3/6 is equivalent to 1/2
6 is a because 1/6 is less than half
If Mercedes alone could paint the house in 8 hours, we would expect that both painting together would take less than 8 hours.
In 1 hour: Dorie would paint 1/12 of the house, while Mercedes would paint 1/8. This is a total of 1/12 + 1/8 = 5/24. If they can combine to paint 5/24 of the house in 1 hour, then the total time for the whole house would be
1 / (5/24) = 24/5 = 4.8 hours or 4 4/5 hours
Answer:
$1.23
Step-by-step explanation:
To find how much they should charge, you have to find how much toilet paper they are selling compared to the bulk store. They are selling 6/72 or 1/12 of the rolls, meaning they should charge 1/12 the amount. To find this, simply divide 14.75 by 12, which is ~1.23$.
Answer: 48
Step-by-step explanation:
We have to write a system of equations:
The difference between two numbers is 29. Difference means one number (y) minus another number (x) equals 29.
y-x =29
If five times the smaller ( 5 times x , x is the smaller number because is the number to subtract) is subtracted from twice the larger, (2y)
The result will be one
2y-5x =1
Now, we have to multiply the first equation by 2, and subtract the second equation to the first one:
2y -2x = 58
-
2y-5x =1
__________
3x =57
Solve for x:
x =57/3 =19
Replacing the value of x on any equation:
y-x =29
y-19 =29
y = 29+19 = 48
48 (y)> 19(x)
