You would convert 17 1/4 to 17 4/16, and change 7/8 to 14/16. Then you would add those 2 numbers together to get 17 18/16 or simplified, 18 1/8.
Answer:
A = 201.0 mi^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know that r = 8
A = (3.14) *8^2
A = 3.14 * 64
A = 200.96 mi ^2
Rounding to the nearest tenth
A = 201.0 mi^2
Answer:
16 and 4
Step-by-step explanation:
Let (x+y) =20 and (x-y)=12 then:
Isolate for x in each equation
x=20-y and x=12+y
Set the equations to equal each other since the value of x should be the same for both
20-y = 12+y
Rearrange so that y is on one side and the numbers are on the other
8 = 2y
y= 8/2
y= 4
Now substitute the y- value back into either of the original equations
x+y= 20
x+4 = 20
Rearrange and isolate x
x = 20-4
x = 16
So the two values are 16 and 4
