Answer:

9

Step-by-step explanation:

First, write the equation.

C(n) = 4 + 3n

We know that C(n) = 31, so we can substitute it.

31 = 4 + 3n

Subtract 4 from both sides to isolate the term with the variable.

27 = 3n

Divide both sides by 3 to get the variable by itself.

9 = n

The value of n such that C(n) = 31 is true is 9

Given the cost in dollars, of a cafeteria meal plan as a function of the number of meals  purchased, n as:

If the cost value C(n) is 31, hence;

31 = 4 + 3n

3n = 31 - 4

3n = 27

n = 27/3

n = 9

Hence the value of n such that C(n) = 31 is true is 9

Answer:

x = -5

Step-by-step explanation:

-6x - 15 = 4x + 35

      + 15        + 15

-6x = 4x + 50

-4x   - 4x

-10x = 50

-10x/-10 = 50/-10

x = -5

Answer:

x = 9

Step-by-step explanation:

Perimeter of rectangle = 2(l+b) = 42

=> 2(x+3 + x)

=> 2 (2x + 3) = 42

=>  4x + 6 = 42

=> 4x = 42 - 6

=> 4x = 36

=> x = 36/4

=> x = 9

Hope it helps :)

Answer:

Formula = (l + b) x 2= 42 so answer = x=9

Step-by-step explanation:

l =x

b =x+3

( x+x+3) * 2 =42

2x +3 x 2 = 42

2x +3 = 42/2

2x +3 = 21

2x = 21 - 3 =18

x = 18/2

x=9

The required x-intercept is (7, 0) and the y-intercept is (0, 3).

In the equation intercept is the value of the linear function where either of the variables is zero.

Here,
To find the x-intercept, we need to find the point at which the graph intersects the x-axis. This occurs when the y-coordinate is zero.

The x-intercept is therefore (7, 0).

To find the y-intercept, we need to find the point at which the graph intersects the y-axis. This occurs when the x-coordinate is zero.

The x-intercept is therefore (0, 3).

Thus, the x-intercept is (7, 0) and the y-intercept is (0, 3).

3(x - 10)

Step-by-step explanation:

3x - 30 = 3(x - 10)

Hii!

__________________________________________________________

Answer:

3(x-10)

Step-by-step explanation:

Note that both terms, 3x and -30, have a 3 in common. This is called the greatest common factor, or g.c.f.

The g.c.f. of 3x and -30 is 3. So we divide both 3x and -30 by 3, and obtain

x-10

Put parentheses around x-10

(x-10)

Next, put 3 outside the parentheses

3(x-10)

c. When number of exercises is no more than 10. This point is the intersection of the lines (10, 350)

Answer: x= 10

Step-by-step explanation:

Same side exterior angles sum to 180.

Using this axiom we can say that

142+ (3x+8) = 180

Add like terms on the left side

150+ 3x = 180

Subtract 150 from both sides

3x = 30

Divide both sides by 3

X= 10

Add 8 to both sides.
