Your answer would be x=3. You would start by combining like terms such as 5x and -7x and getting -2x. Then you would move the +5 to the other side by subtracting it from both sides. You would get -6=-2x. After that you would divide -2 on both sides and since they are both negatives, it would be a positive 3.
Well, I'm not sure since you didn't post the equation but, all you have to do is plug in the number 4 where x is. So for example, say the equation given to you was y=6x+5. Just plug in 4 for x and you get y=6(4)+5, which is y=29.
Answer:
C (because as the number of cups sold goes up, so does the profit) (and its not dots)
Step-by-step explanation:
D could be if they only sold one cup, but started with a profit already. (maybe mom payed THEM to start up the stand?)
Answer: 123
Step-by-step explanation: TO solve problems like this, you should assign a variable to the lowest number, lets just say n. From here, since we know the numbers are consecutive, we can see that the numbers are n, n+1, and n+2. Therefore:
n(first number) + (n+1)(second number) +(n+2) (3rd number) =366
>n+n+1+n+2=366
3n+3=366
3n=363
n=121
n+2=123
