Snowcat [4.5K]

Answer:

4.6 hours

Step-by-step explanation:

Let 'S' be the number of study hours, 'C' be the number of class attendance hours and 'G' be his prior GPA. His new GPA is given by:

$GPA = 0.5S+0.25C+0.25G$

For C = 4 hours and G = 2.75, the number of study hours required to reach a GPA of 4.0 is:

$4.0 = 0.5S+0.25*4+0.25*2.75\\S=\frac{4.0-1-0.6875}{0.5} \\S=4.6\ hours$

Sam needs to study 4.6 hours in order to get a 4.0 GPA.

Factor the equation x2-2x-15=0

Free_Kalibri [48]

Answer:

(x + 3)(x - 5)

Step-by-step explanation:

Well to factor x^2-2x-15,

we need to find 2 numbers that multiply to get -15 and add to get -2.

3*-5 = -15

3x + -5x = -2x

x*x = x^2

Factored (x + 3)(x - 5)

Three times the sum of a number and 12 is 45 plz help!

Norma-Jean [14]

This can be written as 3(n+12)=45, where n is the unknown number

3(n+12)=45 <- Starting Equation

3n+36=45 <- Distributive Property

3n=9 <- Cancel 36 on both sides

n=3 <- Divide both sides by 3

So n=3

Hope this helped!
