Using the quadratic formula works but if you know there are 2 answers (highest power of problem tells you how many solutions) then
10x^2 = 5x
So either x = 0, giving 0=0. Or divide by 5x
2x = 1
x = 0.5
They diagonal through the interior of the cube is the longest. The hypotenuse is the longest side of a right triangle. The diagonal of the cube is the hypotenuse of a right angle with legs that are diagonal of a face and an edge. The edges are the shortest. They are legs of a right triangle with the diagonal of a face as the hypotenuse.
J=john
m=mary
j is 2 times as old as mary
j=2 times m
sum is 21
m+j=21
find mary
subsitute
j=2m therefor subsitute 2m for j
m+2m=21
add like terms
3m=21
divide by 3
m=7
mary=7

Answer:
<h2>Pass = $17.22</h2><h2>Lunch = $8.94</h2>
Step-by-step explanation:
People = 34 + 4 = 38
Pass price per person = 654.36 / 38 = $17.22
Lunch price per student = 303.96 / 34 =$8.94
Pass = $17.22
Lunch = $8.94
