Answer:
1. area of new pen = 11
2. i. 5 feet by 2 feet
ii. 2 ½ feet by 4 ½ feet
Step-by-step explanation:
The size of the pen as planned = 5 ft long by 4 ½ ft wide
Area of the pen = length x width
= 5 x 4 ½
= 5 x
Area of the pen =
= 22 ½
But, Krista has to make the pen ½ the size of planned. So that;
area of new pen = ½ x 22 ½
= ½ x
=
= 11
area of new pen = 11
The area of the new pen would be 11 .
The possible values she could use are:
i. 5 feet by 2 feet
ii. 2 ½ feet by 4 ½ feet

Answer:
There are 36 green marbles, 24 red marbles and 16 blue marbles.
Step-by-step explanation:
Let x be the number of days
Let y be miles travelled
Let z be total cost
a) 55x+0.45y=z
55x+0.45(300)=$2,335
b) 55x+135=$2,335
55x=2335-135
55x=2200
x=2200/55
x=40
c) She spent 40 days
