The answer depends on what type of division it is. Synthetic?
Answer:
The number is <u>less than</u> 3.5
Step-by-step explanation:
Let us break up and convert each individual phrase into its equivalent in an equation.
"Three time" is
"The difference of a number and three" is (3-x)
"Is greater than" is >
"The number decreased by five" is (x-5)
We can now put all of these parts together to get our equation
Now, we can simplify this and solve for x

Answer:
See below.
Step-by-step explanation:
When Brian passes Alex they both have travelled the same distance.
Call this distance d.
Let the speed that Brian passes = x miles/hour.
Distance = speed * time so:
For Alex:
d = (x - 5) * 1.5 ( Alex cycles for 1 + 30 minutes = 1.5 hours)
For Brian:
d = x * 1
So substituting d = x in Alex's equation:
x = 1.5(x - 5)
x = 1.5x - 7.5
7.5 = 0.5x
7/5 / 0.5 = x
15 = x.
ANSWER:
Brian's speed is 15 miles/hour.
Alex's speed is 15 - 5 = 10 miles/hour.
