Answer:

Step-by-step explanation:

Use part/whole proportions. 10/25 (15 + 10) = 12/x. Multiply 12 times 25 (300) = 10x (10 times x). 300 = 10x, isolate x by dividing both sides by 10 and you get 30 = x.

Question 1

777dan777 [17]

Answer:

There would be 94 tiles.

Step-by-step explanation:

The number of tiles is given by the following equation:

$n = 6 + 4p$

In which p is the current position.

How many tiles would there be in position 22?

This is n when $p = 22$ . So

$n = 6 + 4*22 = 6 + 88 = 94$

There would be 94 tiles.
