During his vacation, Dalyn rents a small boat from a rental service that charges a flat fee of $30 plus $10 per hour (including taxes). The total charge comes to $110. Which equation can be used to calculate the number of hours, X, that Dalyn rents the boat?
A 10x + 30 = 110; 8 hours
B 10(x + 30) = 110; 8 hours
C 30x + 10 = 110; 7 hours
D 30(x + 10) = 90; 7 hours

A. 10x + 30 = 110; 8 hours

Step-by-step explanation:

We get A as our answer because we know that there is an hourly fee of 10 so we can write that as 10x. Next we know we have an inital fee of 30. So in our equation we would just write it as 30. Finally we know what the total was. 110. So that would go into our equation as 110. So our final equation would be 10x + 30 = 110. Then when you solve it you get 8 for our missing number. In this cause 8 = x.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
