Simple, first find a common denominator, 24.
So,
7/4*6= 42/24
and
5/6*6=30/24
Then just add,
42/24
+
30/24
Making it 72/24.
72/24=3
Thus, your answer is, 3.

Answer:
higher education
Step-by-step explanation:
it makes most sence if you choose mine
Let hot dogs = X
So then soda would be 2x ( two times as much).
Now you have:
X + 2X = 162
Simplify:
3x = 162
Divide both sides by 3:
X =162 / 3
X = 54
2x = 54 *2 = 108
108 sodas and 54 hot dogs were sold.
You can write the equation using conventional symbols as
3x^2 - 2x - 5 = 0
You can recognize that the middle coefficient is equal to the sum of the other two, so those two coefficients can be used to factor the equation.
(1/3)(3x +3)(3x -5) = 0 . . . . . put the coefficients in the form (1/a)(ax + ...)(ax + ...) (x+1)(3x-5) = 0 . . . . . simplify
The solutions are the values of x that make one or the other of the factors equal to zero.
x = -1
x = 5/3
