Answer:
Let Lance represented by L and Nick represented by N
As per the statement:
Lance has three times as many pencils as Nick
⇒ .....[1]
It is also given that:
They have 84 pencils together.
⇒ .....[2]
Substitute the equation [1] into [2] we have;
⇒
Divide both sides by 4 we have;
N = 21
Substitute this in [1] we have;
L = 3(21) = 63
Therefore, Lance has 63 pencils and Nick has 21 pencils
Answer:
The ordered pairs that are presented are (7, 99.5) and (3, 51.5)
Step-by-step explanation:
We are given the cost function of the carnival rides as
which is a typical linear expression of the form where here
,
,
and
. To check if an ordered pair i.e. a point
, is represented by the table we can simply plug in the equivalent
value in the equation, and check if the result matches the
value.
So, lets assume that all points are given correctly and they are as follow:
Now let us check each point with our function as follow:
<u>Point A</u>
So point A is part of the equation.
<u>Point B</u>
So point B is NOT part of the equation.
<u>Point C</u>
<u /><u />
So point C is part of the equation.
<u>Point D</u>
<u /><u />
So point D is NOT part of the equation.
