22. each sport needs at least two teams so multiply 5x2 and 6x2 then add the numbers. 10+12=22
Usually, the more often it's compounded, the better. That's assuming that the percent is equal through all comparisons, however.
we know that
Perimeter of a triangle is equal to
P=a+b+c
where
a,b and c are the length sides of the triangle
<u>Find the perimeter of the triangles</u>
<u>Triangle N 1</u>
P=(x-2)+(x)+(3x+1)-------> P=5x-1
<u>Triangle N 2</u>
P=(2x-5)+(x+4)+(6x-7)------> P=9x-8
equate the perimeters
5x-1=9x-8--------> 9x-5x=-1+8-------> 4x=7
x=7/4------> x=1.75
therefore
the answer is
x=1.75
Answer:

Step-by-step explanation:
Given

Represent charges with d and time with h
So:
when 
Required
Determine the formula

In other words,

Convert to an equation

Where
k = constant of proportion
Substitute values for Charges and Time

Solve for k


Substitute 15 for k in 


<em>The above formula models the situation</em>
