Answer:

16

Step-by-step explanation:

Given the equation, 200 + 10x = 120 + 15x, let's solve for x as follows,

Subtract 200 from both sides

200 + 10x - 200 = 120 + 15x - 200

10x = - 80 + 15x

Subtract 15x from both sides

10x - 15x = - 80 + 15x - 15x

-5x = - 80

Divide both sides by -5

\frac{-5x}{-5} = \frac{-80}{5}

x = 16

Answer:

Step-by-step explanation:

Absolute Value. Absolute value describes the distance of a number on the number line from 0 without considering which direction from zero the number lies. The absolute value of a number is never negative. The absolute value of 2 + 7 is 5.

Has two solutions x = a and x = -a because both numbers are at the distance a from 0. ... An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.

Answer:

12.43ft

Step-by-step explanation:

 From the given diagram, we simply apply the sin rule

According to the sine rule

=

   y is the side y

    y° = (90 - 43) = 47

    z = 17

    z° = 90

Input the parameters and solve;

            \frac{y}{sin 47}  = \frac{17}{sin 90}

       ysin 90 = 17 sin 47

         y = 12.43ft
