Answer:
10 classes
Step-by-step explanation:
Given equations in the question
Dance World: y = 15x
Toe Tappers: y = 25 + 12.5x
Where,
x = number of classes
Equate the total cost at both dance studios
15x = 25 + 12.5x
Collect like terms
15x - 12.5x = 25
2.5x = 25
Divide both sides by 2.5
2.5x / 2.5 = 25 / 2.5
x = 10 classes
x = number of classes = 10
Answer:
A
Step-by-step explanation:
really ? you need help to calculate the 2 results of
(2 ± 6) / 2
?
one result is
(2 + 6) / 2 = 8/2 = 4
the other result is
(2 - 6) / 2 = -4/2 = -2
there ! that is all there is to it.
is there still something unclear ?
