Answer:
Option 2nd is correct.
Step-by-step explanation:
In right angle triangle:
Pythagoras theorem follows which is:
Here, c= hypotenuse b is one side and a is the other side.
Therefore, according to Pythagoras theorem Option 1,3 and 4 are discarded.
Option 2nd is correct because KL=EF and triangle KLM and EFG follows Pythagoras theorem which makes them a right angle triangle.
Answer is c. you subtract 4 to both sides and get 3x=21 and then divide 3 to both sides to get x=7
Answer:
100-10 = 15x
Step-by-step explanation:
You are subtracting 10 because that is how much is still left, its not included in the total spent.
15 represents the money spent per shirt, and x is the amount of shirts purchased
For this case, we must find the quotient of
divided by
, to verify if Tina was correct.
So:
So, Tina was wrong, she had to divide by 3x.
Answer:
Option B
