Alex has $68, which is $20 more than Michael has. How much money does Michael have? Which expression best represents the statement above? A. x + 20 = 68 B. 20 - x = 68 C. 60 - 20 = x D. 60 - x = 21

A. x+20=60

Step-by-step explanation:

Start with what you know: Alex has $68 and that is $20 more than Michael. Think, what number is 20 less than 68? The number is 48. You can plug 48 in for x in each answer choice or you can derive the answer by creating your own equation. Make x=how much Michael has. Since Alex has $20 more dollars, Michael has 20 fewer dollars than Alex. so x=68-20. The only answer choice that is equal to that is A.

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
