Answer:
29 units
Step-by-step explanation:
The length of a segment of a number line is the difference of the coordinates of the end points:
45 -16 = 29
Answer:
thats the equation for slope-intercept form
Step-by-step explanation:
m is the slope and b is where the line intercepts on the y axis
Let the width be x cm.
Then length=3x-4 cm.
Its perimeter is 64 cm.
We know that perimeter of a rectangle= 2(length+width)
So,
2(3x-4+x)=64
6x-8+2x=64
6x+2x=64+8
8x=72
x=9
Therefore,
length=(3×9-4)cm=(27-4)cm=23 cm.
Width=9 cm.
Answer:

Step-by-step explanation:
To isolate r, we're going to need to do some algebraic manipulation.

Multiply both sides by r:

Divide both sides by a:
