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.
