Answer:
The equation would be .
Step-by-step explanation:
Given;
Total Number of Video games = 21
Let the number of video game Nicholas has be 'x'.
Now Given:
Robert has 5 fewer games than Nicholas.
so we can say that;
number of video game Robert has =
Also Given:
Charlie has twice as many games as Robert.
so we can say that;
number of video game Charlie has =
we need to write the equation.
Solution:
Now we can say that;
Total Number of Video games is equal to sum of number of video game Nicholas has, number of video game Robert has and number of video game Charlie has.
framing the equation we get;
Hence The equation would be .
On Solving we get;
Adding both side by 15 we get;
Dividing both side by 4 we get;
Hence Nicholas has = 9 video games
Robert has = video games
Charlie has = video games
Given:
The given equation of line is
To find:
The equation of line that passes through (-5,4) and is parallel to the given line.
Solution:
Slope intercept form of a line is
...(i)
where, m is slope and b is y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get
Slope of given line is .
Slope of parallel lines are same. So, slope of parallel line is .
The required line passes through (-5,4) with slope . So, the equation of line is
Adding 4 on both sides, we get
Therefore, the correct option is a.
Answer:
The correct unit price would be $1.23.
The contractor divided 103.32 by 7, resulting in an error.
Step-by-step explanation:
If we know a dozen equals 12, then 7 dozen looks like:
Multiply.
Now we know the contractor purchases 84 pairs of padded work gloves.
Let's find our unit price:
<em>unit price =</em>
Substitute.
<em>unit price = </em>
Divide.
<em>unit price = </em><em />
<em>__</em>
To find the error of the contractor, let's try substituting in a number (7) provided in the question to see if we get $14.76 per pair:
Divide.
