Commercial jet's speed = 2x-162 (plug this in the equation below)
Private jet's speed = x
Equation:
10(x) = 8(2x-162)
10x = 16x - 1296
6x = 1296
x = 216 (Private jet's speed)
Take the first equation and plug x value in;
2x-162
2(216) - 162 = 270 ( Commercial jet's speed)
Answer:
X < -3
Step-by-step explanation:
4 - 3x > 13
First move the 4 over, subtract from both sides:
-4 + 4 - 3x > 13 - 4
-3x > 9
Now move the -3 over, divide on both sides.
When you multiply or divide by a negative, you have to reverse the sign.
-3x/-3 < 9/-3
X < -3
The surface area of a sphere is given by the formula
SA = 4pi r^2 = 4 • Pi • 60^2 = 4Pi 3600 = 14 400 Pi m^2.
This is the solution.
