Lian is deciding which of two gyms to join. each gym charges a monthly rate plus a one-time membership fee.
lian correctly wrote and solved a system of linear equations by substitution to compare the costs of the memberships. in her work, she substituted an expression for one variable and solved for the other. this resulted in the equation 75 = 75. what can lian conclude?
a one gym charges $75 per month.
b each gym charges $75 per month.
c both gyms charge the same monthly rate and the same membership fee.
d both gyms charge the same monthly rate, but not the same membership fee.

C Both gyms charge the same monthly rate and the same membership fee.

Step-by-step explanation:

Each gym charges a monthly rate plus a one-time membership fee.

This resulted in the equation 75 = 75.

The total fee for the gym includes both the monthly charges plus one time membership fee.

If the equation is equal at the end, this means both the gym have same charges.

Therefore, option C is correct. Both gyms charge the same monthly rate and the same membership fee.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
