Chris paid $7.35 for 3 oranges. how much does each orange cost? My answer is below

7.35 /3 =c
$2.45
Is this correct?

Simplify
7x^2 + 4.5y-3y + x^2-5x

my answer 7x^2 + 1.5y-5x
is this correct?

8 x^2 - 5 x + 1.5 y

Thanks Damon. Can you explain how the 7 changes to an 8?

what about the first equation is my answer correct?

7 x^2 + x^2 = 8 x^2

The first one was correct.

For the first question, your answer is correct. To determine the cost of each orange, you divided the total cost ($7.35) by the number of oranges (3). This gives us $2.45 per orange.

Regarding the second question, let's simplify the expression step by step:

7x^2 + 4.5y - 3y + x^2 - 5x

First, combine the like terms:

(7x^2 + x^2) + (4.5y - 3y) - 5x

Now, simplify within each group:

8x^2 + 1.5y - 5x

So your answer, 8x^2 + 1.5y - 5x, is correct.
