Answer:
73.437= 74 437/1000
Step-by-step explanation:
73.437 to fraction.
Let's acknowledge the presence of a decimal and how many digit we have after the decimal point.
Actually, the numbers after the decimal point will determine the amount of 10s to be divided with.
What I'm saying is this
73.437= 74 437/1000
In this case, 437 is a prime number
So
73.437= 74 437/1000
Answer:
or 
Step-by-step explanation:
To solve the quadratic equation we must factor the expression
Look for 2 numbers that when you multiply them, obtain the result -100 and when you add them, obtain the result -15.
You can verify that these numbers are -20 and 5

Then the polynomial factors are

The zero product property says that if two terms
then

Answer: x=40 y=140
Step-by-step explanation:
To work out x:
The angles in a triangle always add up to 180.
You already have one angle which is 50 the bottom left angle is a right angle and right angles always equal 90. To work out x, do 50+90=140 then do 180-140=40.
To work out y:
Angles on a straight also add up to 180.
So as you have figured out what x is (40) you would take it away from 180 to give you y.
180-40=140
Hope this helps :)
