The first thing you should do is calculate how many pounds of cheese a hamburger has
1 hamburger = 1/4 pound of cheese.
Then, you can make a rule of three to know how many pounds of cheese were sold:
1 ---> 1/4
310 ---> x
Clearing x we have:
x = ((310) / (1)) * (1/4) = 77.5
Answer
they sell last saturday 77.5 pounds of cheese
9x + 27
-2y + 20
4x - 24
30x + 12xy
15x + 2 (?)
~ I’m not sure abt the last one! I’m sorry if they’re incorrect and I hoped this helps! ~
(21 * 1.10) / 3 = 23.10/3 = 7.7....so each friend has to pay $ 7.70
When solving a linear equation (in one variable), there are three possible outcomes: one solution, no solution, and infinitely many solutions.
You know you have one solution when you get to a situation like “x= a number”. That means that’s the only x-value that makes the equation true.
If you get to something like “2=6” which is not true, that means the equation cannot ever be made true, so there is no solution to that equation.
If you get to something like “2=2” which is always true, that means the equation is always true, no matter what value you pick for the variable. This type of equation has infinitely many solutions.
In terms of your specific question, the third answer is the one that is a true statement.
