Problem:
The area of the patio of a relative's house is 20 square meters.
The width of the patio is 2 meters.
What is the length of the patio?
Solution:
The area is:
A = (w) * (l)
Where,
w: width
l: long
Clearing l we have:
l = A / w
Substituting values:
l = 20/2
l = 10 meters
0.2 is the same as 2/10
18/(2/10)
As you may have learned in school, when you divide a fraction, you flip the fraction in the denominator, and change it to multiplication
18/(2/10) becomes 18 x (10/2)
multiply normally
18 x 10 = 180
divide to find answer
180/2 = 90
90 is your answer
hope this helps
Remember, when you meet this problem, flip the second fraction, and change the division sign into multiplication. (always second, never first (if first is a fraction)).
Answer:
y − 1 = -2 (x − 3)
Step-by-step explanation:
Point slope form is:
y − y₁ = m (x − x₁)
where m is the slope and (x₁, y₁) is a point on the line.
Given that m = -2 and (x₁, y₁) = (3, 1):
y − 1 = -2 (x − 3)
