Verify the equation below with each of the values listed for z to find a solution . 3-2z=1/10

For this case we have the following equation:

We must find the value of z that represents the solution of the equation:

We follow the steps below:

We multiply by 10 on both sides of the equation:

We apply distributive property to the terms of parentheses;

We subtract 30 from both sides of the equation:

We divide between -20 on both sides of the equation:

If we substitute the value of z in the original equation, equality is satisfied.

27 +27 or 27times 2=54

the diffrence is 0

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
