What is Equivalent Equation?
- The mathematical equations which give the same value when solved.
- These equations can be interchanged into one another.
- They are very useful in solving mathematical problems.
Given: Formula
P = (3w + 20)/200
Now, we will convert this in the form of P.
⇒ P = (3w + 20)/200
multiply both sides by 200, we get:
⇒ 200 P = 3w + 20
⇒ 200P - 20 = 3w
⇒ w = (200P - 20)/3
Therefore, the formula after making w as the subject becomes:
w = (200P - 20)/3

Answer:
Step-by-step explanation:
I assume the correct formula is
P = (3w + 20)/200
Solve for w.
200P = 3w + 20
200P - 20 = 3w
(200P - 20)/3 = w

49.67mph
Step-by-step explanation:
Data: 53 miles
1 hour 4 minutes.
Convert 4 minutes to hours:
4/60 = .067
Add like terms (hours)
1+ 0.067= 1.067
mph = m/h
mph = 53/1.067 = 49.67mph
The average speed of the car will be 49.67mph.
What is speed?
The speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. The speed is a scalar quantity and does not require any direction to represent it.
Given that Chloe drives from her house to her grandma's house 53 miles away in an hour and 4 minutes. The speed will be calculated by using the formula below:-
Distance traveled = 53 miles
Time = 1 hour 4 minutes.
Convert 4 minutes to hours:
4/60 = .067
Add like terms (hours)
1+ 0.067= 1.067
Now the speed will be:-
Speed = Distance / Time
Speed = 53 / 1.067
Speed = 49.67 mph
Therefore, the average speed of the car will be 49.67mph.

Answers
Answer: PART A:
The generic equation of the line is:
y-yo = m (x-xo)
First we look for the slope of the line:
m = (y2-y1) / (x2-x1)
m = ((5000) - (6000)) / (4-3)
m = -1000
Then, we substitute any point in the generic equation:
(xo, yo) = (4, 5000)
Substituting:
y-5000 = (- 1000) (x-4)
Rewriting:
y = -1000x + 4000 + 5000
y = -1000x + 9000
The equation is:
y = -1000x + 9000
PART B:
For the price of 3.50 we have:
