Mario says that the expression
has four terms: 4, 3, n, and 2. Mario is incorrect
<em><u>Solution:</u></em>
Given that the expression is:

Given that, Mario says that the above expression has four terms
But Mraio is incorrect
Because the given expression has two terms only
4 is one of the term
is another term
So there are totally 2 terms only
A term can be a signed number, a variable, or a constant multiplied by a variable or variables
Here 3 is a constant multiplied by 
So,
is one term
Each term in an algebraic expression is separated by a + sign or - sign
Thus there are two terms in mario expression
Answer: C is correct, 4x=8
Step-by-step explanation:
You will add the two equations...
4x-8=0
Now you need to move the -8 over, which reverses its sign to positive.
4x=8
Step-by-step explanation:





so the answer is 40
15X=12X+12
Subtract 12X
3X=12
X=4
yellow car = x
white cars = 9x ( 9 times as many white cars)
9x +x = 40
10x = 40
x = 40/10 =4
4 yellow cars
9*4 = 36 white cars
