There are originally 4 white chips 4 multiplied 3 equals 12 so there are 6 green chips because 6 multiplied by 2 also equals 12
Answer:
x = 21/4
Step-by-step explanation:
re-arrange the equation
-4+5x-7-3x = 10-2x (move 3x to the other side)
-4+5x-7-3x+2x = 10 (move 2x to the other side)
5x-7-3x+2x = 10+4 (move 4 to the other side)
5x-3x+2x = 10+4+7 (move 7 to the other side)
4x = 21 (add up both sides)
x = 21/4 (divide both sides by 4
A concession stand vendor counts the money in the register.
=> 1 h, it has $42.75.
=> 5 h, it has $260.75.
260.75 - 42.75 = 218 are added to the money after 4 hours
=> 218 / 4 hours = 54.5 per hour
=> 54.5 * 3 additional hours = 163.5
=> 163.5+260.75=424.25
Answer:
D
Step-by-step explanation:
The volume of a cylinder is pi * r^2 * h
A) V = 3.14 * (0.7/2)^2 * 6.2 = 2.4 m^2
B) V = 3.14 * (0.9/2)^2 * 3.4 = 2.2 m^2
C) V = 3.14 * (1.2/2)^2 * 6.8 = 7.7 m^2
D) V = 3.14 * (1.4/2)^2 * 6.2 = 9.5 m^2
