Answer:
x = 62
Step-by-step explanation:
X and 62 are vertical angles and vertical angles are equal.
x = 62
Answer:
The current area of the circle is 81π in².
They want to " 'decrease' " the radius to 9 in.
First, find the current radius for the current circle.
Areas of circle = πr²,
81π = πr²
First, divide π from both sides of the equation:
(81π)/π = (πr²)/π
r² = 81
Isolate the variable, r. Root both sides of the equation:
√(r²) = √(81)
r = √( 9 * 9) = 9
The radius currently is 9 in.
The NBA is not making any changes at all, therefore the question will be void. (Note that the other answer choice is -9, however, you cannot have a negative measurement, therefore, the answer is voided).

Answer:
x= hot dogs
y= soda
Total sold
1 x + 1 y = 87 .............1
2 x 0.50 y = 78.50 .............2
Eliminate y
multiply (1)by -0.50
Multiply (2) by 1.00
-0.50 x -0.50 y = -43.50
2 x + 0.50 y = 78.50
Add the two equations
1 x = 35.00
/ 1
x = 35.00
plug value of x in (1)
1 x + 1 y = 87
35 + y = 87
y = 87 -35
y = 52
y = 52.00
x= 35 hot dogs
y= 52 soda
