Set up a proportion like this

=
So your proportion would be:

We put x for offices because they are asking for the number o offices a crew can paint in 12 hours, and also we don't know the number of offices they can paint in 12 hours
so we cross multiply and we get
6x=60, we got 60 by multiplying 12 and 5
Now we divide both sides by 6 and we get
x=10
S the crew can paint 10 offices in 12 hours.
Answer:
Value : c = ad - b
Step-by-step explanation:
Given the equation: Solve for c;
Multiply both sides by d in we get;
subtract b from both sides we have;
Simplify:
ad - b = c
Therefore, the value of c is, ad -b
Answer:
The total amount that the consumer had to pay for both products was $ 94.50.
Step-by-step explanation:
Given that Mal sold a large photo for $ 50 and a large frame for $ 40, and that the sales tax for these products is 5%, to determine the total amount that the consumer had to pay to purchase these products arises from the following calculation:
(50 + 40) x 1.05 = X
90 x 1.05 = X
94.5 = X
Therefore, the total amount that the consumer had to pay for both products was $ 94.50.
<span>Based on this sample, and assuming the word "widget" means removed, the answer is four. They only tested 50 bottles and found four (one under, three over). The question also contains the word "Jack's, " the meaning is unclear. The factory shipped 1000 bottles of Hosta sauce, assuming the same ratio as the random sample (0.0008%) then the factory shipped 80 bottles that are incorrect.</span>
