How it's evaluated:
(1) w - k = -7 - -5
(2) -17 - -5= = -17 + (-15)
(3) -17 + (-15) = -2
First step is change W and K and change it into it's correct number.
Second step is change the subtraction sign to it's opposite.
Third step is subtract -17 and (-15) which would give you -2
Answer:
first you must know how many 3/4 do you have
because of scale
and after that multiply to 5 to get actual length
To find the decimal value of a fraction, you simply divide the numerator by the denominator. In this case, we are dividing 4 by 20, which is equal to .2. Therefore, the decimal value that is equal to 4/20 is 0.2.
The equation for the area of a circle is:
A=π*radius squared.
Since radius is half of the diameter.
Diameter/2=radius
Then plug it into the equation.
