A bag contains four red marbles, two green ones, one lavender one, three yellows, and one orange marble. HINT (See Example 7.] H
Murljashka [212]

Answer:  35

Step-by-step explanation:

Given : A bag contains four red marbles, two green ones, one lavender one, three yellows, and one orange marble.

Total = 4+2+1+3+1=11

To find sets of four marbles include none of the red ones, we need to exclude red marbles when we count the total number of marbles.

Then, the total marbles(exclude red) =11-4=7

Now, the combination of 7 marbles taking 4 at a time is given by :-

^7C_4=\dfrac{7!}{4!(7-4)!}=\dfrac{7\times6\times5\times4!}{4!3!}=35

Hence, the number of sets of four marbles include none of the red ones = 35

RUDIKE [14]

Answer:

SolutioN :

  • Set up an equation & solve for x :

\star \tt \: 15x - 7 - 3x + 151 = 180 [ Sum of co-interior angles ]

\longrightarrow \tt \: 12x + 144 = 180

\longrightarrow \tt \: 12x = 36

\longrightarrow \tt \: x =  \frac{36}{12}

\longrightarrow \tt \: x =  \boxed{ \tt{3}}

  • The value of x is 3 .
