Answer:
D. 740
Step-by-step explanation:
Put the given value of b into the formula and do the arithmetic:
A(150) = 5×150 -10 = 750 -10
A(150) = 740
The band raised $740 from their sales.
Division can be used. For example
50/16=3.125gallons
or you could use multiplication
50*1/16=3.125gallons
Answer: 1200= 4s+h
Step-by-step explanation: solve! I don’t know how many equations
F ( x ) - the number of seats in the 1st row;
s ( x ) - the number of additional seats in the next row;
An equation that predicts the number of seats in any row:
g ( x ) = f ( x ) + s ( x )
g ( x ) = 12 + 3 ( x - 1 )
The number of seats in the 30th row:
g ( 30 ) = 12 + 3 * ( 30 - 1 ) = 12+ 3 * 29 = 12 + 87 = 99 seats
A question such as this one is a little tricky since the people seated are not in a straight line.
For a circular table seating question, (n-1)! formula is used. Without restrictions 5! people can be seated.
You might be wondering why it is not 6!, this is because the first person will the the 6 person so you are accounting for the same person twice.
Hope I helped :)
