Answer:
x = -6
Step-by-step explanation:
Here we have an equilateral triangle. All three sides have the same length, 2. Therefore, the interior angles are all equal to 60 degrees.
Therefore, 6 - 9x = 60, and -9x = 54. Dividing both sides by -9 results in
x = -54/9, or x = -6.
The range of the data is C. 160 because the biggest number, 280, subtracted by the smallest number, 120, is equal to 160.
Answer:
b. x>1
Step-by-step explanation:
2/3+x/3>1
Multiply the inequality by 3 to get rid of the fractions
3(2/3+x/3)>1*3
2 +x >3
Subtract 2 from each side
2+x-2 >3-2
x>1
9 I think because 1/4 needs to have 4 of those to be a whole so yeah 9.
The answer is A because when you add the angles to get they equal 180. Then just solve for x.
