1/3x+5=12 i do not understand this math equation

x = 21

Step-by-step explanation: First, isolate the x term by

subtracting 5 from both sides of the equation.

We get 1/3x = 7.

Next, multiply both sides of the equation by

the reciprocal of 1/3 which is 3/1 to get x by itself.

On the left, 3/1(1/3) cancels and on the

right when we multiply 7(3/1), we get 21.

So we have x = 21.

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.

the answer is 24
