Answer:

n > -5

Step-by-step explanation:

Step 1: Distribute

-2n - 40 < 5(6 + n) + 7n

-2n - 40 < 30 + 5n + 7n

Step 2: Combine Like Terms

-2n - 40 < 30 + 5n + 7n

-2n - 40 < 30 + 12n

Step 3: Add 2n to both sides

-2n - 40 + 2n < 30 + 12n + 2n

-40 < 30 + 14n

Step 4: Subtract 30 from both sides

-40 - 30 < 30 + 14n - 30

-70 / 14 < 14n / 14

-5 < n

Answer: n > -5

In the literal equation below, what do C and F represent? F = C + 32

ladessa [460]

Hi!

Let's take a look at the equation:

F = C + 32

What do we notice?

C and F are both variables.

Variables are unknown numbers represented by a letter.

In this case, C and F are the variables.

Hope this helps!
