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.
Is this multiple chose? if so I would like to see the answers. But just using my brain, I would say, 5, or 7.
Answer:
24 wheels
Step-by-step explanation:
A car has 4 wheels
There are 6 cars
4*6 = 24
6 cars has 24 wheels
Multiply both the numerator and denominator by 100
the answer is
645/500
Divide the numerator by 5 and the denominator by 5 to get
129/100
Simplify to get
1.29
<em>x -> Eddie's age</em>
<em>y -> Fred's age</em>
<em>x=3y</em>
<em>x=y+32</em>
<em>3y=y+32</em>
<em>2y=32</em>
<em>=>y=16 => Fred is 16</em>
<em>x=3*16=48</em>
<em>=> <u>Eddie is 48</u></em>
