Bear in mind that words like "are" or "is" is replaced by an equal "=" sign in the equation.
more than or increased by denotes addition
twice the number denotes two times the number
times, simply means multiply.

Let x be the unknown number in the equations.

12 birds are 3 more than twice the number of birds Rhonda saw yesterday.

12 = 2x + 3

Negative 6 times the sum of a number and 4 is 2

-6(x+4) = 2

Four time a number increased by 3 is -89

4x + 3 = -89

Hope this helps!

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.
