Question

Sally has been measuring a flower for a science project. The flower has grown \dfrac{1}{2}
2
1
​
start fraction, 1, divided by, 2, end fraction of a centimeter each day and grown a total of 222 centimeters taller.

Answer 1

let 'x' represent the number of months that Sally has been measuring the tree (1/2)x = 2 multiply both sides by 2

x = 2*2

x = 4 months

Sally has been measuring the tree for 4 months.

let 'x' represent the capacity of the plane

(5/6)x = 150

by solving we find

x = 180 passengers

the capacity of the plane is 180 Passengers.
