Given that make an expression for divide 50 by half and add 20 and multiply by 2.
The expression will be solved as below,
E = 50/2 + 25 x 2 + 50 + 20
Solve the above expression by PEMDAS,
E = 25 + 50 + 70
E = 145

Answer:
-12
Step-by-step explanation:
To evaluate the expression the known value of a = -8 can be substituted in so the equation becomes -8 - 4.

Answer:
In 517 ways
Step-by-step explanation:
There are total 6 people in ballot and voters can vote for any 4 we have following choices
Voter may not vote for anyone then
Since, and
Here, n=6 and r=0 we will get
Voter may not vote for one of them then
Voter may not vote for two of them then
Voter may not vote for three of them then
Voter may not vote for four of them then
Total ways in which a person can vote is
+ + + +
Substituting the values we will get
[tex]1+6+30+120+360=517[/text] ways.
