Multiply 3005 by 0.817 to get your answer. Doing this gives you 81.7% of the total people surveyed which happens to be the amount of people who 'use at least one prescription medication' as outlined by the problem.

So you have to figure out 81.7% of 3005.
3005 ÷ 2 = 1502.5 = 50%
3005 ÷ 5 = 601 = 20%
3005 ÷ 10 = 300.5 = 10%
3005 ÷ 100 = 30.05 = 1%
3005 ÷ 1000 = 3.005 = 0.1%
Then you just add
1502.5 + (601 + 300.5) + 30.05 + (3.005 x 7)
1502.5 + 901.5 + 30.05 + 21.035
= 2455.085 (the answer)
The answer above is if you have a calculator/if it's a calculator question

What is the correct answer?
Vedmedyk [2.9K]

Welcome to the era of LeBron. If you thought he was doing the game a disservice by being a sore loser and egomaniac, you haven’t seen anything yet. It wasn’t enough that he decided to become a pariah, he and his group of cronies have decided they want to ruin the NBA.

How? By systematically turning every superstar in the NBA into LeBron James. They are trying to turn them into spoiled, delusional, lying, quitting cowards.

Two of the biggest stories this offseason have been the drama in Denver and New Orleans. Both players, for whatever reasons, have decided that they no longer want to be the cornerstone of a franchise. Before the summer of Lebron, neither had really been asking to get out of their situations. So what is the common thread here? Well, both are represented by agent Leon Rose. Who else is represented by Rose? Why Mr. James, of course.

Answer:

Option B: 3x + 3y - 3

Step-by-step explanation:

In an isosceles triangle, the two congruent sides are equal.

We are told the base is; x - y - 2 units

Now let each of the congruent sides be represented as A.

Thus the perimeter equation will be;

P = 2A + x - y - 2

Now, we are told that the perimeter is; 7x + 5y - 8 units

Thus;

7x + 5y - 8 = 2A + x - y - 2

Rearranging gives;

7x - x + 5y + y - 8 + 2 = 2A

2A = 6x + 6y - 6

Divide through by 2 to give;

A = 3x + 3y - 3 units
