and so on, and then, you graph those x,y coordinates
Answer: 
Explanation:
The equation is:
The term on the left consists of a product of two different factors: therefore, this product can be zero if either the first term (2x-5) or the second term (3x-1) is equal to zero.
This means that we can solve separately for the two terms:
Solving the first equation:
Solving the second equation:
1. We assume, that the number 40 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 40, so we can write it down as 100%=40.
4. We know, that x% equals 21 of the output value, so we can write it down as x%=21.
5. Now we have two simple equations:
1) 100%=40
2) x%=21
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=40/21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 21 is what percent of 40
100%/x%=40/21
(100/x)*x=(40/21)*x - we multiply both sides of the equation by x
100=1.90476190476*x - we divide both sides of the equation by (1.90476190476) to get x
100/1.90476190476=x
52.5=x
x=52.5
now we have:
21 is 52.5% of 40
Answer:
4,020
Step-by-step explanation:
mean = average
- Ideally, in order for us to have a 3,700 pound average, each of the four trucks would be 3,700 pounds. Added up, we would have a total of: 14,800 pounds (3,700×4)
- Let's see how much pounds we already have:
- 3,250 + 3,890 + 3,640 = 10,780
Now we need to find how much pounds we are missing: 14,800 - 10,780 =
<h2>4,020
for the fourth truck</h2>
- Let's check: 3,250 + 3,890 + 3,640 + 4,020 = 14,800
- 14,800/4 = 3,700 pounds
