Answer:

x=1/3

Step-by-step explanation:

3x-1=1-3x

add three to both sides: 3x(+3x)-1=1-3x(+3x)

6x-1=1

add 1 to both sides: 6x-1(+1)=1(+1)

6x=2

divide both sides by 6: x=2/6

simplify: x=1/3

The sides of a triangle are 7, 4, n. If n is an integer, state the largest and smallest possible values of n.
Sladkaya [172]

Answer:

4, 10

Step-by-step explanation:

b-a < n < b+a where a and b are the two other sides of the triangle and b>a

7-4 < n < 7+4

3 < n < 11

Since n is an integer

4 would be the smallest value and 10 would be the largest

3. n(Sample space) can be calculated by 

     a. counting, a good ways to organize counting is drawing a tree diagram, CHECK THE PICTURE

or     
     b. There are 2 possible outcomes each time we throw the dice so 2*2*2=8 is the total number of outcomes, that is the number of the sample space.

4. So finally P(getting all head)=\frac{1}{8}
