Answer: 70
Step-by-step explanation:
Solve the equation in the innermost parentheses first that means solving 4+1 =5
The next step would be subtracting 9 from five which gives you 4
Next multiply 3 to 4 which gives you 12
Then multiply 5 with 12 which equals 60
Now you have the equation 60+20/4*2
Solve the division and multiplication part of the equation first because of the rule pemdas which shows multiplication comes before addition
First divide 20/4 which gives you 5 then multiply with 2 which gives you ten
After dividing and multiplying you are left with the equation 60+10
The answer is 70
I'm assuming you were given these four values
50.1, -50/2, -50.1, sqrt(50)
where 'sqrt' stands for 'square root', and the slash symbol means divide or fraction.
If my assumption is correct, then the term that does not belong is sqrt(50). This is because the other values are all rational. We can express them as a fraction of two whole numbers
- 50.1 = 501/10
- -50/2 is already a fraction, no need to do any work for this one
- -50.1 = -501/10
But we can't do the same with sqrt(50). It is irrational. Note how 50 is not a perfect square. Your calculator will show that sqrt(50) = 7.07106781186548 and that decimal sequence goes on forever without any pattern. If you were given sqrt(49), then it would work because sqrt(49) = 7 = 7/1.
Answer:
The equation is : x-2y+2=0.
