Answer:

Neither, a has a solution of 9/4

Step-by-step explanation:

a+5a=2a+9

Combine like terms

6a = 2a -9

Subtract 2a from each side

6a -2a = 2a -9 -2a

4a = 9

Divide each side by 4

4a/4 = 9/4

a = 9/4

Neither, a has a solution of 9/4

10)22.666

Step-by-step explanation:

  • To do this first you should convert the mix numbers into inproper fractions and then solve.

1)8/5*5/2=4

2)21/5*20/3=7*4

                  =28

3)33/4*20/9=11*5/3

You pick 4 digits (0-9) at random without replacement, and write them in the order picked. what is the probability that you have
Sophie [7]

The number of ways of choosing 4 digits from 10 digits without replacement ( order is important) is P(10,4)=\frac{10!}{(10-4)!} =\frac{10!}{(6)!} =7*8*9*10=5040. This is the number of all possible permutations of choosing 4 from 10. The first 4 numbers of your phone number is a unique 4 digit number(4 different digits). The required probability is

\frac{1}{5040}
