Solving a linear equation, we conclude that she made 5 batches of cookies.
<h3>
How many batches of cookies has she made?</h3>
We know that Alexis bought a bag that contains 8 cups of m&m's. First, she uses two-thirds of a cup to make each batch, so for x batches, she needs:
B(x) = (3/5)*x
That linear equation tells us how many cups are used to make x batches.
We know that at the end, she has 5 cups, and she started with 8 cups, so she used:
8 cups -5 cups = 3 cups.
Now we need to solve the linear equation:
B(x) = 3 = (3/5)*x
Solving the linear equation for x we get:
3 = (3/5)*x
3*(5/3) = x
5 = x
This means that she made 5 batches of cookies.

The expression 5x+3 would be three more than five times a number! More than in this case would be addition - so if you get the same problem with subtraction you just change more to less!
Basically what it's tell you is that if x stood for 2 in this case 5*2 = 10 since it's 3 MORE than 5 times a number (x is in place of a number), you're adding 3 to 10 and that gives you 13!
I hope I simplified it a little more and you understand!
Good luck, rockstar! c: I hope this helped!
Answer: (1,-1)
Step-by-step explanation:
- You can multiply the first equation by -1
- Add the equations.
- Solve for x, as following:
- Substitute the value of x into any of the original equations and then you must solve for y:
Therefore, the solution is: (1,-1)
