Answer:

The value of the equation is x=\frac{12-y}{5+4k}.

Step-by-step explanation:

Consider the provided equation.

12-5x-4kx=y

We need to solve the provided equation for x.

Subtract 12 both side.  

12-12-5x-4kx=y-12

-5x-4kx=y-12

Take -x common as shown:

-x(5+4k)=y-12

Divide both sides by 5+4k.

-x=\frac{y-12}{5+4k}

x=\frac{-y+12}{5+4k}

x=\frac{12-y}{5+4k}

Hence, the value of the equation is x=\frac{12-y}{5+4k}.

Minus 12 both sides
-5x-4kx=y-12
undistribute x
x(-5-4k)=y-12
divide both sides by (-5-4k)
x=\frac{y-12}{-5-4k}
x=\frac{12-y}{4k+5}

In ΔMNO, the measure of ∠O=90°, the measure of ∠M=74°, and OM = 5.4 feet. Find the length of NO to the nearest tenth of a foot.
jeka94

Answer:

18.8 feet

Step-by-step explanation:

\tan M = \frac{\text{opposite}}{\text{adjacent}}=\frac{x}{5.4}

tanM=

adjacent

opposite

​

=

5.4

x

​

\tan 74=\frac{x}{5.4}

tan74=

5.4

x

​

5.4\tan 74=x

5.4tan74=x

Cross multiply.

x=18.832\approx \mathbf{18.8}\text{ feet}

x=18.832≈18.8 feet

Type into calculator and roundto the nearest tenth of a foot.
