D
Step-by-step explanation:
(0, 0) (0, 1) (1, 2) (1, 3)
For it to be a function each x value should have one y value.
There are two 0's for x and two 1's for x. This is how you can tell it's not a function.
The larger the number is in front of the negative the smaller the number is. Fir example -90 is smaller than -5.
Solution
For this case we have the following equation given:
And we can distribute the terms first ans we got:

Then we can aggrupate the terms like this:

Then we can solve for n like this:

5n =15
n = 15/5= 3
Answer:
1200 ft in one hour
Step-by-step explanation:
The ratio of Sam crawling 20 ft in one minute can be written as:
20:1
Multiply the ratio by 60 to get the minutes to 60 minutes, because there are 60 minutes in an hour:
20 : 1
×60 ×60
To get:
1200:60 ⇒ This means Sam can crawl 1200 ft in 60 minutes, which is the same as 1200 ft in one hour.
