Arthur has 6 more than 5 times the number of pencils as Jenny. If Arthur and Jenny combined have 30 pencils, how many pencils do
1 answer:
Answer:
Jenny has 4 pencils.
Step-by-step explanation:
Let
Jenny has pencils = x
Arthur has pencils = 5x+6 (Arthur has 6 more than 5 times the number of pencils as Jenny. )
Total pencils = 30
We need to find how many pencils does Jenny have.
We basically can write the equation:
Total pencils = Jenny pencils + Arthur pencils
Putting values and solving to find value of x:
So, we have value of x = 4
Now, finding number of Jenny pencils:
Jenny has pencils = x = 4
Therefore, Jenny has 4 pencils.

The solution is about a distance-time graph. The interpretation of the graph is that it took the family 6 hours to travel a distance of 360 miles. Note that the distance is plotted on y-axis and time on the x-axis.
<h3>What is a distance-time graph?</h3>A distance time graph is a simple graph that shows the relationship between the time travelled the distance covered while doing do.
The slope-intercept form is
y= mx+b−⋯(1)
The y-intercept is 360
⇒b = 360; and m = −60
Substituting the value of m = −60
and b = 360
in (1) above,
⇒y = −60x +360
The x-intercept is
y = 0,
⇒0= −60x+360
hence, x=6
The y-intercept is
x=0
⇒y=−60(0)+360
⇒y=360
In conclusion, the x - intercept is the time in hours between Cincinnati and St. Loui: and
The y - intercept is the distance between Cincinnati and St. Louis.
