Complementary angles are angles that add up to 90 degrees. 2x is the first angle. Let y be the second one.
y+2x = 90
Subtract 2x from both sides.
y = 90 - 2x.
The second option is your answer. Have is nice day! :)
Answer:
The answer to your question is letter D
Step-by-step explanation:
Letter A. It is not possible because it is necessary to considers the variable (number of weeks)and this option does not consider it.
Letter B. It is not possible besides it consider the number of weeks the results do not correspond with the conditions given.
Example: for week 1, the number of freckles is 10 + 2¹ = 10 + 2 = 12, and the number of freckles must be 20.
Letter C. It is incorrect because the numbers of freckles do not correspond with the conditions.
Example: week 2 f = 2(10) ² = 2(100) = 200, it is higher than the expected.
Letter D. This is the correct answer because it satisfied the conditions given.
72*10=720 so all the numbers would need to add to 720
the median is 74 so you need to have both 75 and 76 in the set
the mode is 68 so that need to be in at least twice
and the range is 21 so the largest number-21=smallest number
57, 68, 68, 68, 75, 76, 76, 77, 77, 78
0.75 (decimal) is equal to 3/4 (simplified fraction)
