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.

=1/2n - 6n + 3/8 +5
=6.5n + 5.375
Answer:
The blank would be 64 and the answer would be 16
Step-by-step explanation:
Because we are looking for 25% of something, we simply multiply .25 by whatever that number is. So we start with
.25 * ________
And then we put the number in
.25 * 64 = 16
