For this case, the first thing we must do is define variables:
x: unknown number (1)
y: unknown number (2)
We now write the equations that model the problem:
their sum is 6.1:

their difference is 1.6:

Solving the system we have:
We add both equations:

Then, we look for the value of y using any of the equations:
Answer:
The numbers are:
<h2>

21 scoops.
<h2>
Step-by-step explanation:</h2>
It is given that:
Beaus recipe for granola bars calls for 3 1/2 cups of oatmeal.
i.e. the cups of oatmeal required is:

i.e.

Also, he has:

This means that:

Answer:
The product of the expression is -12s² + 11st - 2t²
Step-by-step explanation:
(-3s + 2t)(4s - t)
Use the foil method to multiply the terms. So, we distribute -3s to (4s - t) and we will also distribute 2t to (4s - t) as well.
-12s² + 3st + 8st - 2t²
Now combine like terms.
-12s² + 11st - 2t²
X + 2 = 12
subtract both sides by 2
x = 10
