Answer:
(x, y) = (3, 3)
Step-by-step explanation:
Subtract double the second equation from the first.
(2x +3y) -2(x +y) = (15) -2(6)
y = 3 . . . . . . . . simplify
Use the second equation to find x.
x = 6 -y = 6 -3 = 3
The values of x and y are both 3.
Answer:
$31.80
Step-by-step explanation:
The ball will cost 100% of its price plus 6% of its price for a total of 106%.
To use percentages as a factor and multiply, they must be divide by 100, making the multiplication factor version of 106% 1.06.
Multiply the cost of the ball by your multiplication factor:
30 x 1.06 = 31.8
Money is written to two decimal places, making your answer $31.80

Answer:
The value of radius is 34.395..
Step-by-step explanation:
The formula for finding the circumference of the circle is:
C=2πr.
Here we have given the values:
circumference = 216 units
π = 3.14.
r = ?
Substitute the values in the formula:
216 = 2(3.14)r
216=6.28r
Now divide both sides by 6.28.
We get,
216/6.28 = 6.28r/6.28
34.395=r
Thus the value of radius is 34.395...
