Answer:

585/3 = 195 students

Step-by-step explanation:Each group of three created (or used) 9 pictures, so that means three pictures per student.

 

Dividing 585 students by 3 pictures per student means that there are 585/3=195 students.

Answer:

Students(s) = 192.

Step-by-step explanation:

Eq:

3s + 9 = 585 (each group of 3 wrote 9 each, so for every group + 9. S = students and 585 is altogether.)

Isolate the 3s by doing the inverse (-) of addition and we do that by subtracting 9 from itself and 585.

Eq: 3s = 576

Lastly, isolate the s by dividing 3 (inverse of *)

Eq:

576

___

3

( s = 192 )

Komok [63]

Answer:

The answer is D $3.35

Step-by-step explanation:

2.35 + .25x = 1.75 + .40x \\ 2.35 = 1.75 + .40x - .25x \\ 2.35 = 1.75 + .15x \\ 2.35 - 1.75 = .15x \\ .60 = .15x \\   \frac{.60}{.15}  = x \\ x = 4

2.35 + .25(4) = 2.35 + 1 = 3.35

from 100 to 103 is 3

from 194 to 103 is 1

from 107 to 103 is 4

Then find the mean again youll get 18/6 which is 3

Use the discriminant to describe the roots of each equation. Then select the best description. 2m2 + 3 = m.
Tpy6a [65]

The roots of the equation , 2m^{2}+3=m, are non real roots.

<h3>Discriminants are what?</h3>

The quadratic formula's discriminant is represented by the square root symbol b^{2}-4ac. If there are two solutions, one solution, or none at all, the discriminant informs us.

As of now, 2m²+3=m we need to find the kind of roots they have.

2m²+3=m

2m²-m+3=0

Here, we can derive the following values from the equation:

a = 2, b = -1, c = 3

An equation's discriminant is stated as:

D = b²-4ac

D = (-1)(-1) - 4(2)(3)

D = 1 - 24

D = -23

Discriminant can determine the kind of roots that the equation contains.

In this instance, the discriminant is below 0.

The equation's roots are complex conjugates when D < 0.

Hence the roots for the equation are non real roots.
