Answer:

In the given expression the coefficient of x is 3

Step-by-step explanation:

Given that Jill simplified the expression shown

4x-2y-x+5y-8

we have to find the coefficient of the x-term of the fully simplified expression.

Expression:

4x-2y-x+5y-8

Combining like terms, we get

4x-x-2y+5y-8

3x+3y-8

Hence, in the above expression the coefficient of x is 3

What number is 120% of 12
Rasek [7]
120% of 12 is 14.4.I got this by doing this:

12/x=100/120
<span>(12/x)*x=(100/120)*x       - </span>we multiply both sides of the equation by x
<span>12=0.833333333333*x       - </span>we divide both sides of the equation by (0.833333333333) to get x
<span>12/0.833333333333=x </span>
<span>14.4=x </span>
<span>x=14.4</span>

Mario says that the expression 4+3n² has four terms: 4, 3, n, and 2. Is he correct? explain.
stich3 [128]

Mario says that the expression 4+3n^2 has four terms: 4, 3, n, and 2. Mario is incorrect

<em><u>Solution:</u></em>

Given that the expression is:

4+3n^2

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

3n^2 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 n^2

So, 3n^2 is one term

Each term in an algebraic expression is separated by a + sign or - sign

Thus there are two terms in mario expression

Measure of the supplement of angle
lesya [120]
Two supplemental angles add up to 180°
So we have (A + B = 180°)
The measure of one of them is always 180° - the other.
A = 180° - B
B = 180° - A
