One possible inequality would be
1999-x<0.
If you subtract any year after he stepped down from 1999, the year he stepped down, the result will be a negative number.

Answer: The relationship between distance and time is
and the graph is continuous.
Step-by-step explanation:
Since we have given that
Number of hours he hiked = 2 hours
Distance covered = 5 miles
Speed would be

Let the distance be 'd'.
Let the time be 't'.
so, the relation between distance and time would be

The graph is continuous because it is not based on counts and the points are connected with a continuous line without any break.
Hence, the relationship between distance and time is
and the graph is continuous.
we know that
The fraction of each tile color can be found by dividing the number of tiles for each tile by the total number of tiles, then simplifying the fraction if possible.
Let
N----------> total number of tiles
Y---------> number of yellow tiles
B--------> number of blue tiles
P--------> number of purple tiles
we have

<u>1) Find the fraction of yellow tiles</u>
we know that
the fraction of yellow tiles is equal to

substitute the values

<u>2) Find the fraction of purple tiles</u>
we know that
the fraction of purple tiles is equal to

substitute the values

<u>3) Find the fraction of yellow tiles or purple tiles</u>
we know that
the fraction of yellow tiles or purple tiles is equal to

therefore
<u>the answer is</u>

Bella can cut 24 pieces of ribbon from this long strip
<u>Solution:</u>
Given that Bella has 85 feet of ribbons in total
She needs identical strips of ribbon measuring 3.5 feet each
To find: Number of peices of ribbon can she cut from long strip
Number of peices of ribbon can she cut from long strip can be calculated by dividing the total feet of ribbon she has by length of identical strips she needs
<em><u>Mathematically written as:</u></em>


Hence , the number of strip can be 24 each of size 3.5 feet
