Answer:

18x

Step-by-step explanation:

Since all 3 are monomial terms with the same variable, we can add them together:

5x + 3x = 8x + 10x = 18x

Answer: 18x

Explanation: The three parts of this expression, +5x, +3x, and +10x are called terms and the numbers in front of the variables, +5, +3, and +10 are called coefficients.

Because the variables, x, x, and x are identical,

the three terms in this problem are called like terms.

Like terms can be added together

by simply adding their coefficients.

So in this problem, since 5 + 3 + 10 is 18, 5x + 3x + 10 is simply 18x.

Analia wants to know which school has higher athletic achievement relative to the budget per student
user100 [1]

Answer:

SAT average divided by budget per student

Graduation rate divided by budget per student

No. The definitions have opposite results.

Step-by-step explanation:

DID IT ON KHAN and

The key understanding here is that there isn't a single way to define "academic achievement." Graduation rate can be a good measure of that. Average SAT is also a good measure. The rate of students who are accepted into college can also be a good measure, but we are not given information about that.

Now let's go over the options and see which of them might be used to describe "academic achievements relative to the budget per student."

Hint #22 / 4

Definition Analysis Appropriate?

SAT average divided by budget per student "SAT average" is a measure of academic achievement. Dividing this by the budget per student gives us a good definition.

Graduation rate divided by number of sports medals won "Graduation rate" is a measure of academic achievement, but it's divided by the number of sports medals won, and not by the budget per student.

No

Hint #33 / 4

We are left with two definitions for academic achievements relative to the budget per student:

SAT average divided by budget per student

Graduation rate divided by budget per student

Let's calculate the academic achievements relative to the budget per student for each school according to each definition:

Sergio [31]

Given:

The functions are:

f(x)=|3x-5|+7x

g(x)=-2x+9

To find:

The function (f+g)(x).

Solution:

We have,

f(x)=|3x-5|+7x

g(x)=-2x+9

We know that,

(f+g)(x)=f(x)+g(x)

On substituting the values of given functions, we get

(f+g)(x)=|3x-5|+7x+(-2x+9)

(f+g)(x)=|3x-5|+7x-2x+9

(f+g)(x)=|3x-5|+5x+9

Therefore, the required function is (f+g)(x)=|3x-5|+5x+9.

If a+b+b =24 and b-a =4 what is a?​
Lyrx [107]

Answer:

a = 5 1/3

Step-by-step explanation:

a+b+b = 24

a + 2b = 24

b-a =4

a = b - 4

b - 4 + 2b = 24

3b = 24 + 4

b =28/3

substitute this in a = b - 4

a = 28/3 - 4

a = 28/3 - 12/3

a = 16/3

a = 5 1/3
