I would say C sorry if it’s not right
Susan has 50 so the difference is 5 sense sheila had 45
Answer:
third number = 4,
equation of y, y = 5x - 11
equation of n, n = 4x
equation of x, n + x + y =19
Step-by-step explanation:
so lets write evertything as a n equation. n + x + y =19. N is the first number, x is the second number, and y is the third number. We will write the equation for y as follows 5x - 11. N will be four times the second number, so 4x. If substitute the values for out equation for x we will find what x equals to. So (4x) + x + (5x - 11) = 19
10x = 30
x = 3.
Then you substiute the answer for x in the equation for y. This will get you 5(3) - 11
15 - 11
4 = third number
There's a simple formula for finding the arc length.
In radians:<span>
A = θ*r = (2pi/3) x 4 cm = 8*pi/3 cm
Therefore, the answer is letter A </span> <span>8*pi/3 cm.
