Answer:
x = 1
Step-by-step explanation:
When you subtract the smallest number from the biggest number, the answer is called the range. Here the largest number is 21. The smallest is 3. Then the range should be 18. But since it's 20. This mean that x is 1. Because 21 - 1 will equal 20, making 20 the range. So the correct answer is 1.
The tops and bottoms of a trapezoid are parallel, and a polygon's volume and angles are always 360.As long as you know the shape and about three of the lengths, you can find the base.
So 15% is out of 100%, and the cab company has sent 30 cabs out of x?(x is the total number of cabs).

So, by setting up that data we already know, we can make this equation to figure out how many cabs total the company actually has:
<span>15x = 100 * 30
</span>
We do the multiplication on the right side
15x = 3000
And divide to isolate the "X" variable
x = 200
So, the cab company has 200 cabs total, and they sent out 30 of them.
76% = 76 / 100 = 0.76
What is 76% of 670
= 76% * 670
= 0.76 * 670
= 509.2
