1. 0.25x + 15 = 0.05x + 20
0.20x = 5
x = 25
2. 1/3x = x-22
-2/3x = -22
x = 33
Step-by-step explanation:
now even though I cannot find most of the answers for you I can tell you how to solve them, all you need to do is just input the equations that equal the letter pairs then sold them as if it was a find the x equation but in this case we're solving for L and not x
To find this question's answer, we need to know that sum of the exterior angles of any given polygon is 360°. This is default and non-changeable.
Now we know that the sum of all exterior angles is 360°, the question says that one angle is equal to 36°.
When we divide them we get:
So, we found that there are 10 exterior angles.
The perimeter is either 10 (if the rectangle has two sides that are 4in and one side that is 2in) or 8 (if the rectangle has two sides that are 2in and one side that is 4in)
<span>There are 8 girls per 15 campers because 8 divided by 7 boys and 8 girls. The proportion is 8/15. If there are 195 campers, then you are looking for the number of girls, so 8/15 = x/195, where x is the number of girls.
Solve for x.
15x = 8(195)
1560 = 15x
x = 104
104 girls.
Number of boys = y,
195-104=y
y = 91</span>
