Twenty-seven minus of a number (x) is not more than 36. What is the number? A. x > 42 B. x ≥ -6 C. x < 3 D. x ≤ -6

None of them

Step-by-step explanation:

minus a number is not more than translates algebraically to

(Not more than means either or less than that's why we have used equal or less than inequality)

Subtract 27 from both sides

Multiply both sides by -1

Multiplying by -1 will reverse the inequity

Hence values of equal or greater than will satisfy the inequality

Verification:

Lets take

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
