Answer:
-20, -18, -16
Step-by-step explanation:
For consecutive integer problems, it often works well to let a variable represent the middle one (or their average value).
__
Here, we can let x represent the second integer. Then the first is (x-2), and the third is (x+2). The given relation can be written as ...
(5 +x)(-7) = 11 +5(-(x+2))
-35 -7x = 11 -5x -10 . . . . . . eliminate parentheses
-36 = 2x . . . . . . . . . add 7x -1
-18 = x . . . . . . . . divide by 2
The three integers are -20, -18, -16.
ANSWER
-4.0
EXPLANATION
The given trigonometric equation is
From special angles or using the unit circle.
We make the substitution to get:
This simplifies to:
Hence the correct answer is -4.0
53 is the mean
70 is the range
there is no mode
51 is the median
That belongs in the rational #s
(50 g + 20 h - 30) (-12g +16h -8)
38g + 36h - 38
