Answer:

1. 10 inches 2. $7.70

Step-by-step explanation:

For number one they are simply multiplying the width by 2 and for the length, it would be 5 times 2 and you'll get 10 inches.

For number 2, you had to do 21 divided by 3 and get 7. Then find 10% of 21 which is 2.10. Then 2.10 divided by the three people is 0.7. So add 7 and .7 together and get $7.70

Answer:

c = 100, a = 50, s = 20

Step-by-step explanation:

following information is missing from the question

6c + 7a + 2s = 990

3c + 3a + 4s = 430

2c + 4a + 4s = 480

If you solve the equation by putting in the values given in the option you will deduce that only option d matches LHS to the RHS

Lets see how,

6c + 7a + 2s = 990                

where, c = 100, a = 50, s = 20

6(100) + 7(50) + 2(20) = 990

600 + 750 + 40 = 990

990 = 990 hence true

2c + 4a + 4s = 480                     where, c = 100, a = 50, s = 20

2 (100) + 4 ( 50) + 4 (20)  = 480

200 + 250 + 80  =  480

See for the other option too with the same steps done above  to have a more clear understanding :)

How many minutes will it take each of them to arrive at the scene?
elixir [45]

Step-by-step explanation:

If you were to expand your research to include other genres, you'd find that most scenes in most movies are no more than three minutes long, which means no more than three pages of script. It's not an iron-clad rule; scenes can be twenty minutes long. But it's a very useful rule of thumb.
