Answer:
The value of a = -12.
Step-by-step explanation:
Given that the points are Q( -6, 5) and R ( -2, 3) -
As we know that-
If a line segment AB is with endpoints (
) and (
) then the mid points C are-
<em>C = (
,
)</em>
Here,
Q( -6, 5) and R ( -2, 3)
then the midpoints C are-
( a/3, 4) = (
,
)
We have to find the value of x therefore we need to compare only x coordinate -
<em>a/3 = ( -6 - 2)/2</em>
<em>a/3 = -8/2</em>
<em>a/3 = - 4</em>
<em>a = -12</em>
Hence the value of a = -12.

Answer:
$ 198
Step-by-step explanation:
450 + 0.06x = 3750
0.06x = 3750 - 450
x = (3300 * 0.06) = 198
x = 198
