Answer:

Charlie had 1340 more stamps than Ryan

Step-by-step explanation:

altogether, they have 1608 stamps.

Because if Charlie has 5 times more plus Ryan's portion equals 6 portion total.

Divide 1608 by 6  and that equals 268

Meaning that Ryan has 268 stamps.

To confirm, subtract 268 from 1608

this equals 1340.  

268 * 5 = 1340

What is the x-intercept for the following linear equation:
Alexandra [31]
The "x-intercept" occurs when y=0, because it is at this point that the equation touches the x axis.  So if you plug in y=0 into the equation you can solve for the x coordinate.

4x-2(0)-8=0

4x-8=0

4x=8

x=2

So the x-intercept is the point (2,0)

There is a triangle with a perimeter of 63 cm, one side of which is 21 cm. Also, one of the medians is perpendicular to one of t
NemiM [27]

Answer:

21cm; 28cm; 14cm

Step-by-step explanation:

There is no info in the problem/s  text which one of the triangle's  side is 21 cm. That is why we have to try all possible variants.

Let the triangle is ABC . Let the AK is the angle A bisector and BM is median.

Let O is AK and BM cross point.

Have a look to triangle ABM.  AO is the bisector and AOB=AOM=90 degrees (means that AO is as bisector as altitude)

=> triangle ABM is isosceles => AB=AM  (1)

1. Let AC=21   So AM=21/2=10.5 cm

So AB=10.5 cm as well.  So BC= P-AB-AC=63-21-10.5=31.5 cm

Such triangle doesn' t exist ( is impossible), because the triangle's inequality doesn't fulfill.  AB+AC>BC ( We have 21+10.5=31.5 => AB+AC=BC)

2. Let AB=21 So AM=21 and AC=42 .So  BC= P-AB-AC=63-21-42=0 cm- such triangle doesn't exist.

3. Finally let BC=21 cm. So AB+AC= 63-21=42 cm

We know (1) that AB=AM so AC=2*AB.  So AB+AC=AB+2*AB=3*AB

=>3*AB=42=> AB=14 cm => AC=2*14=28 cm.

Let check if this triangle exists ( if the triangle's inequality fulfills).

BC+AB>AC    21+14>28 - correct=> the triangle with the sides' length 21cm,14 cm, 28cm exists.

This variant is the only possible solution of the given problem.

Which unit of measurement would be most appropriate to measure the distance between Atlanta, GA and Nashville, TN? A) centimeter
Helga [31]
The answer to this question should be: C. Kilometers

To answer this question, I will rearrange the option from the smallest unit into the highest unit. 

Centimeter
Inch
Yards 
Kilometer

Centimeter and inch are similar, they are mostly used for measure height of people or object. Yards is used for measuring a field area. Kilometer would be the biggest. It used for roads or expressing distance between city/country. So the answer should be kilometers
