An adult elephant eats about 300 pounds of food each day. write an expression to represent the number of pounds of food a herd of 12 elephants eat in 5 days?

For this case, the first thing we must do is define variables.

We have then:

x: number of days

y: number of total pounds.

For 12 elephants, we have the expression is:

Then, for the given number of days, we have x = 5.

Substituting the value of x we have:

an expression to represent the number of pounds of food a herd of 12 elephants eat in 5 days is:

correct answers below:

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
