Answer: I believe that you wrote it wrong because options a and d are the same thing. The answer is -4x + 2 = 9
Step-by-step explanation:
The word "sum" is used to indicate addition, and "is" is used for equals, so it would be -4x + 2 = 9.
The angle formed by the intersection of tangent and secant outside the circle equals half the difference of the <span>intercepted arcs.
(210 - x)/2 = 50
210 - x = 50*2
210 - x = 100
210 - 100 = x
x = 110</span>°
Answer:
150 one point throws, 165 two points throws and 110 three points throws
Step-by-step explanation:
Let x be the number of free (one point) throws.
The number of free throws Sarah made was 15 less than the number of two-point field goals she made. If y is the number of two points throws, then

so the number of two points throws 
The number of two-point field goals that Sarah made was 55 less than double the number of three-point field goals she made. If z is the number of three points throws, then

so the number of three points throws 
The total score is 810 points, so

Answer:
339π in³
Step-by-step explanation:
The amount of water is the difference between the volume of the cylinder and the volume of the ball. The appropriate volume formulas are ...
cylinder V = πr²h
sphere V = (4/3)πr³
For the given numbers, the volumes are ...
cylinder V = π(5 in)²(15 in) = 375π in³
sphere V = (4/3)π(3 in)³ = 36π in³
The water volume is the difference of these ...
water volume = cylinder V - sphere V
= 375π in³ - 36π in³ = 339π in³
