Determine the equation to find x
First, is to complete the angles of the triangle (ABC and ACB)
--- angle on a straight line
Collect like terms
--- angles in a triangle
Collect like terms
Apply sine rule
In this case:
This gives:
Where is the problem that we have to solve
Howdy,
20% is also 1/5 in fraction form, which tells us he spent 1/5 of his money on clothes:
So to solve, we have to multiply 50 by 5:
50 x 5 = 250
Rocco's original savings was $250

Step-by-step explanation:
A real-life situation for this inequality could be "Tom runs a lemonade stand. His profit is x. If Tom knows that his profit is less than 2 dollars, what inequality represents this situation?"
Let s = northbound train
Then
2s = southbound train
:
Distance = time * speed
4s + 4(2s) = 600
:
4s + 8s = 600
:
12s = 600
:
s = 600/12
:
s = 50 mph is the northbound train
Then
2(50) = 100 mph is the southbound train
:
:
Check:
4(50) + 4(100) = 600
