Using the percentage concept, supposing 520 out of 1000 respondents believe in global warming, 52% of respondents agreed that global warming is occurring.
<h3>What is a percentage?</h3>
The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
![P = \frac{a}{b} \times 100\%](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7Ba%7D%7Bb%7D%20%5Ctimes%20100%5C%25)
In this problem, we suppose that 520 out of 1000 respondents believe in global warming, hence a = 520, b = 1000, and the percentage is of:
![P = \frac{520}{1000} \times 100\% = 52\%](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7B520%7D%7B1000%7D%20%5Ctimes%20100%5C%25%20%3D%2052%5C%25)

First, you should combine the x terms:
-3x - 7 = 29
Then, get rid of the negative 7, by adding 7 to both sides.
-3x = 22
Finally divide 22 by -3, to solve for x.
x = -22/3 or -7.33

idk
Step-by-step explanation:
A) The variable on the horizontal axis of the graph (the independent variable) is "pounds of rice". That is what the first number in the ordered pair (6, 18) represents.
The variable on the vertical axis of the graph (the dependent variable) is "total cost in dollars". That is what the second number in the ordered pair represents.
(6, 18) represents that the total cost of purchasing 6 lbs of rice is $18.
B) The unit price is found at the point where the independent variable has the value 1. That would be at the point (1, 3), which indicates the unit price is $3 per pound.
C) You would have to buy 4 lbs of rice for the total cost to be $12. There are at least two ways to find the answer.
- Draw a horizontal line on the graph at cost = $12. It intersects the graph at lbs = 4.
- Divide the total cost by the unit price. $12/($3/lb) = 4 lb.
Answer: $454.55
Step-by-step explanation:
Tito's weekly salary is always $ 500 per week.
But your weekly commission income depends on the sales you make. Your commissions are 55%.
If we call x the dollar amount of all sales made by Tito in a week, then his income z(x) is given by the following equation:
![z (x) = 0.55x + 500](https://tex.z-dn.net/?f=z%20%28x%29%20%3D%200.55x%20%2B%20500)
We wish that
.
Then we equate the equation to 750 and solve for the variable x.
![0.55x + 500 = 750\\\\0.55x + 500-500 = 750-500\\\\0.55x = 250](https://tex.z-dn.net/?f=0.55x%20%2B%20500%20%3D%20750%5C%5C%5C%5C0.55x%20%2B%20500-500%20%3D%20750-500%5C%5C%5C%5C0.55x%20%3D%20250)
![\frac{0.55}{0.55}x = \frac{250}{0.55}](https://tex.z-dn.net/?f=%5Cfrac%7B0.55%7D%7B0.55%7Dx%20%3D%20%5Cfrac%7B250%7D%7B0.55%7D)
![x = \$\ 454.55](https://tex.z-dn.net/?f=x%20%3D%20%5C%24%5C%20454.55)
Total sales made by Tito must be $454.55
