I too have the same question
I turn the mixed numbers into decimals before doing anything else.
11 2/5----> 57/5----> 11.4
4 2/7----> 30/7----> 4.29
2 1/7----> 15/7----> 2.14
11.4=q-4.29+2.14
11.4=q-2.15
13.55= q
13.55 converted to a fraction is 13 11⁄20
q=13 11⁄20
Answer:
Step-by-step explanation:
Given
The above triangle
First, we calculate the length LM using Pythagoras theorem.
Collect like terms
Take positive square root
Solving (a): Sin L
Simplify
Solving (b): tan N
Simplify
Solving (c): cos L
This calculated as:
Simplify
Solving (d): sin N
This is calculated using:
If
Then:
So:
Answer:
The simplified expression is:
Step-by-step explanation:
Given the expression
Add similar elements
Thus, the simplified expression is:
Carla is correct because they will not all be exactly the same unless they choose to make them all be the same. Hope I could help! :D
