Simplify 2r + 10 + 4r to 6r + 10
Expand it
Simplify 6r + 18 - 4 to 6r + 14
Cancel 6r on both sides
Since 14 = 10 is false, there is NO solution for this equation so no answer.
When i calculated it , it says 993.813
Answer: Girls: 20
Boys: 30

Answer:
10=Z and 10=Y
Step-by-step explanation:
since it is a 45, 45, 90 triangle
both Z and Y will be the same length
the hypotenuse has a length of 
with x being the length of the legs
Since the length of this triangle's hypotenuse is 
the side length would be 10
Hope that helps :)
