The answer to this expression is 8a+32
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:
The inequality is
2 x - 6 > 6(x -2) +8
To solve the inequality we will first use distributive property with respect to multiplication over subtraction
And then bring constant on one side and variable on another side keeping the inequality maintained
2 x -6 > 6 x -12 + 8
2 x -6 > 6 x - 4
6 x - 2 x< -6+4
4 x < -2
Dividing both sides by 2
x < 
Now i will draw the graph of above function.
Answer:
62 miles per hour speed if you drove 325 miles in 5 1/4 hours
Step-by-step explanation:
Using formula:

As per the statement:
if you drove 325 miles in 5 1/4 hours
⇒
miles
and
Time =
hours
Then by above formula we have;
miles per hour
Therefore, 61.90 ≈ 62 miles per hour speed if you drove 325 miles in 5 1/4 hours
