Answer:
They complete the hill in 8 hours
Step-by-step explanation:
We will need to solve these equations with a system of equations, so we need to isolate one variable in one of the equations and then replace it with another equation. After this, this means that Beatrice alone would construct the hill in 24 hours and Charlie 40. So, after finding the value A we will need to add A with B and C. This would get us 
. We will then divide 
. This will leave with 8h.
A= 7/120h
C=1/40h
B= 1/24h
Answer:

Step-by-step explanation:
It is easy
The area of carpet is 13.4×24=321.6sq meter
Now, for 1 sq. meter the cost is $24.99

=$8036.784
Answer:
Step-by-step explanation:
idk number one.
Number 2- the answer is (C) because $6.50 minus the $5 is $1.50 and then that divided by $0.50 is 3.
Number 3- The answer is (A) and i dont feel lie explaining it
Number 4- The answer is (B)
Number 5- Im just going to say that it's probably going to be (C)
Number 6- i think its (D)
When you have to divide by a fraction, you have to multiply the other number by the fraction's reciprocal.
8 = 3/4 w Divide by 3/4
w = 8/(3/4)
w = 8/ (3/4) = 8 x 4/3 Multiply by the numerator and divide by the denominator.
w = (8 x 4) / 3
w = 32 / 3
w = 10 2/3
