Let the number of adults be x, then number of male students is 1 + 7x and the number of female students is (1 + 7x)/2.
x + 1 + 7x + (1 + 7x)/2 = 82
2x + 2 + 14x + 1 + 7x = 164
23x = 164 - 2 - 1 = 161
x = 161/23 = 7
Therefore, number of male students is 1 + 7(7) = 1 + 49 = 50
and the number of female students is 50/2 = 25.
Answer:
Number 200 decreased by 10% (10 percent) of its value (percentage decrease) and calculated absolute change (actual difference). Answer: percentage decreased number = 180, absolute change (actual difference) = -20
Step-by-step explanation:
I think it’s 7 hope this helps you
+ 15 = 64 Subtract 15 from both sides
<span>
= 49 Find the square root of both sides to cancel out the </span>
x + 5 = 7 Subtract 5 from both sides
x = 2<span>

You would need 3 2-dimensional rectangles and 2 2-dimensional triangles to make up a Triangular Prism.
I hope this helps!
