Mr. duc asked to set up 450 chairs in a large hall. Perry puts 20 chairs in each row. He has already set up 15 rows of chairs

Each row consists of 20 chairs

He already set up 15 rows

So number of chairs he already set up = chairs in each row * number of rows

20 * 15 = 300

So , he already set up 300 chairs

Total chairs to set up is 450

Remaining chairs to set up = 450 - 300 = 150

So, 150 more chairs to set up

Talia tossed a penny many times. She got 20 heads and 80 tails. She said the experimental probability of getting heads was 20 80
iragen [17]

Answer:

the experimental probability is 1/5

Step-by-step explanation:

This is because one to calculate the experimental probability one has to divide the favorable events over the possible events, and those that Talia did were the favorable events divided the non-favorable events

20 heads and 80 tails

Faborable events = 20

Possible events = 20 + 80 = 100

20/100 = 1/5

Which expression is equivalent to -5(x+10)?
Kruka [31]
The final expression would be -5x -50.

You could've got this by multiplying -5 and x together, which is -5x.
Multiply -5 and 10 together, and you get -50. 
This is also called the Distributive Property. Hope this helped :)
