Final answer:
Using simple division, Tike Television can fit six one-minute commercials into their six-minute advertising block.
Explanation:
The question is regarding how many one-minute commercials Tike Television can fit into their six-minute advertising block. This is a simple division problem. Assuming that each commercial is exactly one minute long, you would divide the total amount of advertising time (6 minutes) by the length of each commercial (1 minute).
So the calculation would look like this: 6 minutes / 1 minute = 6 commercials.
Therefore, Tike Television can fit six one-minute commercials into their six-minute advertising space.

The 250 pounds of food will last for 20.83 days.
What is an equation?
An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
Initial quantity of food = 250 pounds,
Since, mountain climbers begin to eat 12 pounds per day,
Let the food will last for x days,
The equation can be written as,
12x = 250
x = 20.833
The food will last for 20.83 days.
To know more about Equation on:
#SPJ5
Your equation would be: y=12x+0 because they eat 12 pounds each day and they start out having eaten 0 pounds.
To solve the equation, plug in the total amount of food for y and use algebra to solve for x:
250=12x
(divide by 12)
(250/12)=x
X=20.833
Their food would last approximately 20 days. (Make sure you round if required)
