Answer: 3<em>n</em> ants
Step-by-step explanation:
If there are n ants one month, and the ants triple every month, then next month there will be 3<em>n</em> ants.
We can multiply 3 by <em>n</em> to show it tripling.
To test this, 3(10,000) = 30,000 and 3(270,000) = 810,000, which corresponds to what you've filled out in the table.
Answer:
The right answer is, -420
Step-by-step explanation:
Because we use common factor:
60 (x - 15)
We multiply for each term:
60 (x) - 60 (15)
60 (8) - 60 (15)
We solve:
480 - 900 = -420
Answer:
12 blueberries, 4 strawberries
Step-by-step explanation:
For every 3 blueberries, there is 1 strawberry. So 3 + 1 = 4
As there are a total of 16 berries in the bowl, 16/4 = 4 so there are 4 lots of "3 blueberries and 1 strawberry".
Therefore, there are 3 x 4 = 12 blueberries
1 x 4 = 4 strawberries
