A rectangle is shown. The length of the rectangle is labeled 6 inches. The width of the rectangle is labeled 9 inches. What are the dimensions of the poster at one-third its current size?

1. 2 in by 3 in
2. 3 in by 3 in
3. 18 in by 27 in
4. 12 in by 18 in

1, 2 in by 3 in.

Step-by-step explanation:

It's asking the dimensions of the poster after it's one-third of the size.  So you divide the dimensions by 3.  So 6/3=2 and 9/3=3.  Hopefully this is right and helps you out.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

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).
