Answer:

The correct option is c) n=5.

Therefore the solution to

3n+4=24-n

is

n=5

Step-by-step explanation:

Given:

3n+4=24-n

To Find;

n = ?

Solution:

3n+4=24-n      ........Given

Add + n to both the side

3n+4+ n=24-n+n\\4n+4=24

Now Subtract 4 on both the side

4n+4-4=24-4\\4n=20

Dividing by 4 on both side

\dfrac{4n}{4}=\dfrac{20}{4}\\\\n=5

Therefore the solution to

3n+4=24-n

is

n=5

30 treadmills to 36 elliptical machines the ratio in simplest form
Goshia [24]
30 treadmills : 36 ellipticals
this could be written in a few ways, but i am going to write it as a fraction. since treadmills come first, you put 30/36.

now that you have your fraction you have to find the GCF (greatest common factor) of the two numbers. the GCF is 6, so you have to divide 30 treadmills by 6, and 36 ellipticals by 6.
30/6=5
36/6=6

5/6 or 5:6 is the simplified ratio of treadmills to ellipticals

The perimeter of GHJ
Dafna1 [17]
They have a scale factor of 5:6 so first we need to find the perimeter of KLM:
11 + 14 + 17 = 42
Then apply the scale factor of 5:6:
\frac{5}{6}  =  \frac{x}{42}
Set the denominators equal:
\frac{35}{42}  =  \frac{x}{42}
So we see that the perimeter of GHJ is 35.

Determine the discriminant for the quadratic equation 0=-2x2+3. Based on the discriminant value, how many real number solutions
Arlecino [84]

The discriminant of 0 = -2x^2 + 3 is 24 and it has 2 real solutions

<h3>How to interpret the discriminant?</h3>

The equation is given as:

0 = -2x^2 + 3

Rewrite as:

-2x^2 + 3 = 0

The discriminant of an equation is calculated using:

D = B^2 - 4AC

In this case, we have:

A = -2

B = 0

C = 3

So, we have:

D = (0)^2 - 4 * -2 * 3

Evaluate

D = 24

When the discriminant is 0 or more, then the equation has real roots

Hence, the discriminant of 0 = -2x^2 + 3 is 24 and it has 2 real solutions
