Hey there! :)

3 - (-2) = ??

Let's keep in mind that a negative times a negative is always a positive!

In addition, let's also remember that parenthesis mean multiplication - so that's how we know that we're multiplying!

So, since a negative times a negative equals a positive, then we know that this question is essentially just asking us what 3 + 2 is!

In case we aren't sure how to do this, let's look at our fingers! We start out with 3 fingers, and add 2 more fingers to it! So, 3 fingers to 2 fingers equals 5 fingers!

Therefore, our answer is 5.

3 -(-2) = 5

A farm stand sold 12 ears of corn for 4$ .the farm stand sold 180 ears of corn at the same rate
oksano4ka [1.4K]
To answer this first we set up a proportion and then solve. Lets do it:-

\frac{4}{12}= \frac{x}{80}

Cross Multiply:-

80 · 4 = 320

Divide:-

420 ÷ 12 = 60

So, 180 ears of corn are for $60.

Hope I helped ya!!
