Step-by-step explanation:
Suppose y varies directly as x, and y = 7 when x = 2. Find x when y = 21.
Answer:
Step-by-step explanation:
y = k x X
7 = k x 2
7/2 = k...............1
hence y = 7/2x (substituting eq 1)
y = 21
therefore, x = 2y/7
x = 2 x 21
7
x = 2 x 3
x = 6
The required value of x is 6, when y =21 and y directly varies as x.
What is proportion?A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio.
Given that,
y directly varies as x,
Implies that,
y ∝ x
or y = k x (1)
When x = 2 and y = 7, from equation (1)
7 = k × 2
k = 7 / 2
To find the value of x when y = 21,
Substitute values of k = 7 /2 and y = 21 in equation (1),
21 = (7 / 2) × x
3 × 2 = x
x = 6
The value of x when y = 21, is 6.

A motorboat heads upstream a distance of 24 miles on the Guadalupe River, whose current is flowing at 3 miles/hour. Which expression can represent the total time it takes to complete a round-trip up and back, where b is the speed of the boat in miles/hour?
Answer:
24/b-3 + 24/b+3
Step-by-step explanation:
For PLATO users!!!!
This expression represents the total time, Time = [tex]\frac{24}{b-3} + \frac{24}{b+3}[/tex]
What is distance?Distance is defined as the product of the speed and time.
Given,
b = the speed of the boat in miles/hour
let, effective speed upstream = (b+3)
effective speed downstream = (b-3)
∵Time = distance/ speed
Given that, upstream a distance of 24 miles
Time = [tex]\frac{24}{b-3} + \frac{24}{b+3}[/tex]
This expression represents the total time it takes to complete a round-trip up and back.
