An expression is shown. 4.8 x 2 + 3.2, what is the value of the expression?

Answers

Answer is 23
Explanation is that 4.8 equals 11.5 in trigenomes, so 11.5 times 2 is 23. Happy to help :)

Answer:

12.8

Step-by-step explanation:

follow the steps: parenthesis, exponents, multiplication/division, addition/subraction

so, since multiplication comes before addition, you are going to do 4.8 x 2 before adding 3.2

4.8 x 2=9.6

9.6+3.2=12.8

Given f(x)=3x^2+9x+k and the remainder when f(x) is divided by x+1 is -14, then what is the value of k?

Answers

Answer:

The value of k is -8.

Step-by-step explanation:

Given;

f(x) = 3x² + 9x + k

factor of the function = x + 1

remainder of the function = -14

let x + 1 = 0

x = -1

f(-1) = 3(-1)² + 9(-1) + k = -14

3(-1)² + 9(-1) + k = -14

3 - 9 + k = -14

-6 + k = -14

k = -14 + 6

k = -8

Therefore, the value of k is -8.

what is the value of the x in this equation 6x = 54

Answers

Answer:

x = 9

Step-by-step explanation:

6x = 54

Simple way of solving, all you have to do is isolate the variable "x." To do that, divide the number, 6, by both sides.

6x / 6 = 54 / 6

54 / 6 = 9

Hence,

x = 9

Hope this helps :)

Answer:

x= 9

6x= 54

[tex] \frac{6x}{6} = \frac{54}{6} [/tex]

x = 9

Suppose Ethan has 28 comic books. If the ratio of comic books with Native superheroes to comic books without Native
superheroes is 1:3, how many comic books have Native superheroes?
a. 6 comic books
b. 7 comic books
c. 4 comic books
d. 5 comic books

Answers

Answer:

Step-by-step explanation:

N. comic books : Non N. Comic books=

1:3

Total number of parts= 4

If the total number of parts is 4 then logically , 4 represents 28.

So here we'll write

4 p = 28

I p = 28/4= 7

The native comic books is 1 p.

So we'll write,

1 p = 7 ×1 = 7 comic books

Answers

Answer:

(5,-5)

Step-by-step explanation:

Eliminate y-term

[tex](2x + 5x) + ( - 3y + 3y) = 25 + 10 \\ 7x = 35 \\ x = \frac{35}{7} \\ x = 5[/tex]

We can eliminate x-term but for this system of equations, eliminating y-term is faster.

Substitute x = 5 in any given equations.

I will choose to substitute in the first equation.

[tex]2x - 3y = 25 \\ 2(5) - 3y = 25 \\ 10 - 3y = 25 \\ 10 - 25 = 3y \\ - 1 5 = 3y \\ 3y = - 15 \\ y = - 5[/tex]

Answer Check

Substitute both x-value and y-value in any given equations

[tex]2x - 3y = 25 \\ 2(5) - 3( - 5) = 25 \\ 10 + 15 = 25 \\ 25 = 25[/tex]

The equation is true. (It is better to check both the answer for both equation.)

Thus the answer is (5,-5)

Answer:

11x+7

Step-by-step explanation:

This is because, in order to simplify, first you need to distribute the 2 into the x+5. So, you get 2x+10. Then you get 9x-3+2x+10. The 9x and 2x combine to get 11x. The -3+10 combine to get 7. So you have 11x+7.

Answer:

x=-5

Step-by-step explanation:

0 + 3x = 0 + -15

3x = 0 + -15

3x=-15

Then, x=-5.
