Tom [10]

Adults = 9

Children = 2

Let x be the number of adults.

11-x is the number of children.

22x + 15(11-x) = 228

22x + 165 - 15x = 228

22x - 15x = 228 - 165

7x = 63

7x / 7 = 63 / 7

x = 9 number of adults.

11 - x = 11 - 9 = 2 number of children.

To check:

22x + 15(11-x) = 228

22(9) + 15(11-9) = 228

198 + 30 = 228

228 = 228

An object is launched from a platform.

Bess [88]

Answer:

60 feet

Step-by-step explanation:

The height, h (in meters), of the object launched from a platform is represented by the equation

$h=h(x)=-5x^2+20x+60$

where x is the time (in seconds) passed after the launch.

The time of launch is $x=0$ (0 seconds passed after the launch)

Substitute $x=0$ to find the height:

$h=h(0)=-5\cdot 0^2+20\cdot 0+60=60\ feet$
