Consider a bag containing four red marbles, three green ones, one transparent one, three yellow ones, and three orange ones.

Otrada [13]

Answer: 21

Step-by-step explanation:

Given : Number of red marbles = 4

Number of green marbles =3

Number of transparent marbles =1

Number of yellow marbles =3

Number of orange marbles =3

If we want to count the sets of five marbles are there in which none of them are red or green, the we exclude green and red marbles from the total marbles.

i.e. Total required marbles = 1+3+3=7

Now, the number of possible sets of five marbles are there:-

$^7C_5=\dfrac{7!}{5!(7-5)!}=\dfrac{7\times6\times5!}{5!2!}=21$

Hence, the number of possible sets of five marbles =21

Solve for y. 7y - 6y - 10 = 13

salantis [7]

Start off by combining like terms (your y's).
7y - 6y - 10 = 13
y - 10 = 13

Now you need to get y by itself so add 10 to both sides

y - 10 = 13
+10 +10

y = 23

What's the answer to 1/2(x+4)^2-5+=3.

nadya68 [22]

Answer:

x = 0

Step-by-step explanation:

To solve this equation you would need to get x by itself on one side

1/2 (x+4)^2 - 5 = 3

1.) add 5 to both sides

1/2 (x+4)^2 = 8

2.) divide each side by 1/2

(x+4)^2 = 16

3.) find the square root of both sides

(x+4) = 4

4.) subtract 4 from both sides

x = 0

The app "Photomath" is a great way to solve problems like these and it gives a step by step explanation that might be easier to understand than mine :)
