Let the cost of each drink is $x and the cost of each hot dog is $y.
According to the given data, 3 drinks and 2 hot dogs cost $4.80. In equation form, we can write it as:
1 drink and 1 hot dog costs $2.00. In equation form, we can write it as:
Using this value of x in first equation, we get:
Thus the cost of one hot dog is $1.20
Answer:
x = -3
x = 7
Step-by-step explanation:
If either term is zero the product is zero
(2x + 6)(x - 7) = 0
2x + 6 = 0
2x = -6
x = -3
x - 7 = 0
x = 7
Your answer would ultimately be A because you would multiply 100 by the percent 55 which u would take the dot like it usually is a the end of the number and move it over to the left two places to get your number then you would multiply 100 by .55 to get 55$

Explanation:
The first step is to figure out what the equation is. When unconventional math symbols are used, and when there are no grouping symbols identifying operands, that can be the most difficult step. Here, we think the equation is supposed to be ...
![\sqrt[3]{x+1}-2=0](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%2B1%7D-2%3D0)
It usually works well in radical equations to isolate the radical. Here that would mean adding 2 to both sides of the equation, to undo the subtraction of 2.
![\sqrt[3]{x+1}=2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%2B1%7D%3D2)
Now, it is convenient to raise both sides of the equation to the 3rd power.
Finally, we can isolate the variable by undoing the addition of 1. We accomplish that by adding -1 to both sides of the equation.
The equation is solved. The solution is x = 7.
