This appears to be a composite function situation where you find the value of t(x) and sub that in for the x in c(x). If x = 4, then t(4) = 4(4) + 3 and t(4) = 19. Sub that 19 in for x in c(x) to get 2(19) + 5 which is 43. So 43
Answer:
Y+X=50
Y=2X - 43
X=31 Y=19

Answer: 50.27cm^2
Step-by-step explanation: Area of a circle = pi*r^2
Assuming the shaded area is the area between the outside of the smaller circle and the boundary of the bigger one, it would be
area of big circle - area of small circle
so pi* (5)^2 - pi*(3)^2
=50.27
Answer:
3 cups
Step-by-step explanation:
1/3 cups · 9 friends = 3 cups
To answer this item, we let x be the time for the faster plane and h be the distance traveled which is the same for both planes. Distance is calculated by multiplying speed and time. Thus,
(558)(x) = (496)(x + 0.5)
The value of x from the equation is 4.
