<span>As you have two fractions, you can cross multiply them. This gives: x/a = y/b to ay = xb. Then divide both sides by b to isolate x: ay/b = x.</span>
The square of a positive integer added to 4 times the integer is 437..
x2 + 4x = 437
I chose to do this by completing the square..
x2+4x+4 = 437 + 4
(x+2)2 = 441
Take square root of both sides
x+2 = ±√441
x = -2 ± 21
x = -23 or x = 19
x = 19
Let h be the price of a hamburger, d be the price of a drink, and f for the prices of fries.
2h+3d=12
4f+3h+5d=15
d=1
this is a system of 3 equations.

Use pythagorean theorem;
a²+b²=c² where a and b are the legs and c is the hypotenuse of triangle
5²+b²=10²
b²=100-25
b²=75
b=√75
b=8.66 miles
Hope I helped :)
