Answer:
-5 1/4 would be your answer.
Step-by-step explanation:
Keep in mind that if the question asks you to divide the fractions you have to change it to multiplication. And if you change it to multiplication the fraction that you have to divide with will switch numbers.
Basically I did:
7/8 / -1/6
= 7/8 x -6/1
= 7/8 x -6 = -21/4 = -5 1/4
Answer:
C -16x + 74/5
Step-by-step explanation:
2(x + 7) - 18x + (4/5)
Expand the brackets.
2x + 14 - 18x + (4/5)
Combine like terms.
(2x - 18x) + (14 + (4/5))
-16x + 14 4/5
Convert 14 4/5 to an improper fraction
14 4/5 = ((14 * 5) + 4) / 5 = 74 / 5
Answer = -16x + 74/5
Answer:
25/24
Step-by-step explanation:
sin x = O/H = -7/25
cot x = A/O = -24/7
sec x = H/A
if sin x = -7/25, the opposite side is 7, and the hypotenuse is 25
if cot x = -24/y, the adjacent side is 24 (and the opposite side is still 7)
since H = 25 and A = 24, sec x = 25/24
Also, you know it's positive because when sin x is negative, the angle is in quadrants 3 or 4, and when cot x is negative, the angle is in quandrants 2 or 4, so the only quadrant that satisfies both is 4. In quadrant 4, sec x is positive.
