-3(4r - 8) = -36
Mutiply the bracket by -3
(-3)(4r)(-3)(-8)= -12r+24
-12r+24= -36
move +24 to the other side
sign changes from +24 to -24
-12r+24-24= -36-24
-12r= -60
divide by -12
-12r/-12= -60/-12
r= 5
Answer: r= 5
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.

Let's solve step by step
Step 1: First you need to know that quotient is the answer to a division problem.
Now that we know that we can just divide 26,234 by 42.
Step 1: Divide
You can Divide 26,234 by 42 using a calculator
once you typed in 26,234/42 than should equal <span>624.619047619
Step 3: Round (this step is optional)
To make the answer more clear we can round 624.619047619 to the hundreds place.
</span>
624.619047619 is rounded to <span>624.62
</span><span>
Therefore your answer is </span>624.619047619 or rounded to 624.62. (either answer will be correct)
