Answer
wherever the decimal is, put it directly on top of the dividing line thing. Now that the decimal looks like a regular whole number you can divide like you usually would. Whenever you do regular long division, your answer is always going to be on the top of the line. Your answer should have a decimal in it ... and that should be your answer.
The correct answer to this question is this one: "D. 11.474"
your calculator probably doesn't do "secant". But sec is 1/cos
so do cos(85) (in degree mode, not radian mode)
then "invert it": 1 / ANS or x^-1 if you have that key
or type
1/cos(85 degrees)= <span>11.4737</span>
Answer: x = 17/3 or 5 2/3
Step-by-step explanation:
Let the number be x
ATQ
6(x -4) = 10
6x-24 = 10
6x = 10+24
6x = 34
x = 34/6
x = 17/3
