Answer:

3+2x

Step-by-step explanation:

Distribute the equation out.

1/4(12+8x)

(1/4*12)+(1/4*8x)

Multiple those out to get a new equation

3+2x

You cannot add those together because of the variable. Theres no way of knowing what x equals so this is as far as you can go therefor making the answer 3+2x

The ratio of green beads to yellow beads in a bracelet is three to four. The total number of beads is 14. How many green beads a

Alja [10]

Answer:

There are 6 green beads there.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of green beads

y is the number of yellow beads

The ratio of green beads to yellow beads in a bracelet is three to four.

This means that

$\frac{x}{y} = \frac{3}{4}$

$3y = 4x$

$y = \frac{4x}{3}$

The total number of beads is 14.

This means that $x + y = 14$

How many green beads are there ?

This is x.

$x + y = 14$

However

$y = \frac{4x}{3}$

$x + \frac{4x}{3} = 14$

Using multiplying by the gcm(3)

$3x + 4x = 42$

$7x = 42$

$x = 6$

There are 6 green beads there.

Keith_Richards [23]

Answer:

There are 795 combinations.

Step-by-step explanation:

The number of ways or combinations in which we can select k element from a group of n elements is given by:

$nCk=\frac{n!}{k!(n-k)!}$

So, if Miriam want to choose 3 movies with at least two comedies, she have two options: Choose 2 comedies and 1 foreign film or choose 3 comedies.

Then, the number of combinations for every case are:

1. Choose 2 Comedies from the 10 and choose 1 foreign film from 15. This is calculated as:

$10C2*15C1=\frac{10!}{2!(10-8)!}*\frac{15}{1!(15-14)!}$

$10C2*15C1=675$

2. Choose 3 Comedies from the 10. This is calculated as:

$10C3=\frac{10!}{3!(10-3)!}=120$

Therefore, there are 795 combinations and it is calculated as:

675 + 120 = 795

Combine the following sets of terms.

DanielleElmas [232]

Let's simplify step-by-step To understand :)

3x2−7x−(x2+3x−9)

Distribute the Negative Sign:

=3x2−7x+−1(x2+3x−9)

=3x2+−7x+−1x2+−1(3x)+(−1)(−9)

=3x2+−7x+−x2+−3x+9

Combine Like Terms:)

=3x2+−7x+−x2+−3x+9

=(3x2+−x2)+(−7x+−3x)+(9)

=2x2+−10x+9

Answer :)

=2x2−10x+9
