When we write out the system of equations, we will get:

x+y=18

x-y=8

 We can then use elimination to get just one variable.

 x+y=18

+x-y=  8

 Which gives us:   2x=26

 We then divide by 2 and get:    x=13

 We next plug that into one of the two equations and solve for the other variable:    (13)+y=18

We subtract 13 from both sides and get:   y=5

So the two numbers are 13 and 5.

Which equation is equivalent to 4s=t+ 2?S= 1-2S=4/t+2S =t+2/4 S=t+6
Marina CMI [18]

SOLUTION:

We are to make S the subject of the formula;

\begin{gathered} 4S\text{ = t + 2} \\ \text{Divide both sides by 4} \\ \frac{4S}{4}\text{ = }\frac{t\text{ + 2}}{4} \\ S\text{ = }\frac{t\text{ + 2}}{4} \\  \\  \end{gathered}

The correct option is the third one.

What is the measure of each angle of a regular 26-gon?
lina2011 [118]

Answer:

Angle of Regular polygon = 166.15° (Approx.)

Step-by-step explanation:

Given:

Regular polygon with 26 sides

Find:

Measure of each angle of Regular polygon

Computation:

Angle of Regular polygon = [(n-2)180] / n

where n = number of sides

Angle of Regular polygon = [(26-2)180] / 26

Angle of Regular polygon = [(24)180] / 26

Angle of Regular polygon = [4,320] / 26

Angle of Regular polygon = 166.15° (Approx.)
