The second one is the correct one
Let the number of 30 pound boxes represented by =x
Let the number of 20 pound boxes be represented by =y
As given, there are 64 boxes so equation is:
or ..... (1)
Total weight is 1400 pounds so equation becomes
...............(2)
Plug in the value of in 2nd equation
and
Hence, the number of boxes for delivery that weigh 20 pounds is 52.
D. represents the relation.
<span>A chord is a segment whose endpoints are on the circle. A secant is a line that intersects a circle at two points. if you draw a circle, with center O,</span>
You are gonna do rise/run.
So you have 1/4 for the first two points.
Then you have 2/8 which can be simplified down to 1/4.
So the slope of the line is 1/4.
Hope this Helps!!
