Answer:
x = 8
Step-by-step explanation:
Step 1: Subtract 5x from both sides.
Step 2: Add 2 to both sides.
Step 3: Divide both sides by 2.
Step 4: Check if solution is correct.
Therefore, x = 8.
Answer:
5.619
Step-by-step explanation:
SOH 22 =x/15
cross multiply
X =SOH 22 *15
X =0.3746*15
X =5.619
It is convenient to do part b first, then use that result to do part a.
b. For some pair of points (x1, y1) and (x2, y2), you want to find a point (a, b) such that (a, b) - (x1, y1) = (x2, y2) - (a, b). That is, the differences of coordinates from one end to the center are the same as the differences from the center to the other end.
Adding (a, b) to the above equation gives
2(a, b) - (x1, y1) = (x2, y2)
Adding (x1, y1) then gives
2(a, b) = (x1, y1) + (x2, y2)
Finally, dividing by 2 gives a formula for (a, b):
(a, b) = ((x1, y1) + (x2, y2))/2
The midpoint is the average of the end points.
a. Using the result from part b, the midpoint is
midpoint = ((2, 3) + (6, 7))/2 = (8, 10)/2
midpoint = (4, 5)
