Answer:
Step-by-step explanation:
Let r represent Linda's walking rate.
We have been given that Linda can ride 9 mph faster than she can walk, so Linda's bike riding rate would be 
miles per hour.
We have been given that Linda can bicycle 48 miles in the same time as it takes her to walk 12 miles.
Since both times are equal, so we will get:
Therefore, the equation can be used to solve the rates for given problem.
Cross multiply:
Therefore, Linda's walking at a rate of 3 miles per hour.
Linda's bike riding rate would be 
miles per hour.
Therefore, Linda's riding the bike at a rate of 12 miles per hour.

Answer:
Tim will get 8 and Sam will get 32
Step-by-step explanation:
If an object has a density of less than 
g/ml, the object will float in water.
So, fourth option is correct
The object with density less than g/ml will float, and the object with a density more than g/ml will sink.
So, if an object has a density of less than g/ml, the object will float in water.
Therefore, fourth option is correct

Answer:
1) 16
2a) 100 -a -2b
2bi) (100 -a -2b)/4
2bii) 11
Step-by-step explanation:
1. Put the numbers where the corresponding variables are and do the arithmetic.
(2(1) +3(-2))^2 = (2 -6)^2 = (-4)^2 = 16
__
2. The pieces cut from the wire have the lengths a, b, b. The sum of those lengths is a+b+b = a+2b.
2a. The remaining length is what is left when the total of cut pieces is subtracted from the original amount:
100 -(a+2b) = 100 -a -2b
2bi. The perimeter of the square is the amount in part (2a). A square has 4 sides of the same length, so each side has a length that is 1/4 of the perimeter. The side length is ...
(100 -a -2b)/4 . . . . length of one side of the square
2bii. Fill in the given values for "a" and "b" and do the arithmetic.
(100 -24 -2(16))/4 = (76 -32)/4 = 44/4 = 11 . . . one side of the square
