Answer:
I tried to answer but I still would like to know what doesn't make sense.
Considering the identity:
The identity is true whenever both sides are defined. It is not supposed to hold the values when we have division by zero, because it is undefined.
If the value doesn't make sense, it is probably not a function, or it is undefined by the given value of .
Let's go back to the definition of function again:
A function relates a set of inputs and a set of allowable outputs where each input is related to only one output. It basically defines the relation of ordered pairs.
Hope it helped you a bit.
Answer:
x=20
Step-by-step explanation:
By the Triangle Sum Theorem, the angles of a triangle add up to 180. So we can set up the equation like this:
2x-10+70+4x=180
Combine Like terms
6x+60=180
Subtract 60 from both sides
6x=120
Divide by 6 to isolate the variable
x=20
Find the LCD (least common denominator)
15 in this case
Convert to have 15 as denominators
1/3 = 5/15
2/5 = 6/15
Subtract
(6/15) - (5/15)
1/15
He had 1/15 less
