Answer:
Step-by-step explanation:
It is given that, the radius of a circle is 8 inches and we are to find the circumference of the circle.
To find the circumference of the circle we must know this formula first :
Where
- r is the radius of the circle.
- We'll take the value of π as 3.14
Now substituting the values in the formula :
Therefore,
- The circumference of the circle is 50.24 inches
<h3>The solution is (x, y) = (3, -24)</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
-3x - y = 15 -------- eqn 1
y = -8x ------ eqn 2
We have to find solution of (x, y)
We can solve by substitution method
<em><u>Substitute eqn 2 in eqn 1</u></em>
-3x - (-8x) = 15
-3x + 8x = 15
5x = 15
Divide both sides by 5
<h3>x = 3</h3>
Substitute x = 3 in eqn 2
y = -8(3)
<h3>y = -24</h3>
Thus solution is (x, y) = (3, -24)
The answer is 3, just do 20*0.15 (covert 15% into a decimal).
2/3
