Solve for u.
u/7 - 1 = 1

U = 14

Step-by-step explanation:

u = 14

u/7 - 1 = 1

add 1 to both sides

u/7 = 2

multiply 2 by 7

u = 14

here you hope this .

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.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
