This seems to look like a factoring question. When factoring, one must know that the second number is the sum of the two values multiplied by x, and the third number is what happens when one multiplies those two numbers. Using these definitions, one can conclude that the correct answer is (x-8)(x+3)
Answer:
Step-by-step explanation:
Let c represent the number of children that attended the concert.
Let a represent the number of adults that attended the concert.
At one of the concerts, each adult brought 4 children with them, and 10 children attended without an adult. This means that the number of children that attended is
c = 4a + 10
Tickets for a concert were $5 for each child and $8 for each adult. The total ticket sales were $1730. It means that
5c + 8a = 1730
Therefore, the systems of equations that can be solved to determine the number of children, c, and adults that attended the concert is
c = 4a + 10
5c + 8a = 1730
Answer:
Cost of the manicure= $27
Step-by-step explanation:
Giving the following information:
Darcy gave her nail technician a $5.40 tip. The tip was 20% of the cost of the manicure
<u>To calculate the cost of the manicure, we need to use the following formula:</u>
Cost of the manicure= tip / tip percentage
Cost of the manicure= $27
K(x)=moles
p(x)=rollls
subsitute k(x) for x in p(x)
p(k(x))=2(x-1)+3=2x-2+3=2x+1
that is
p(x)=2x+1 for
p(x)=rolls
and x is toes
