Answer:
3x3-45÷(4+1) is 0.
Step-by-step explanation:
We have to do order of operations so we follow PEMDAS:
P is for Parentheses so we do what's in parentheses first:
(4+1)=5
E is for Exponents but we don't have exponents.
Next is M and D for Multiplication and Division. We have division before multiplication so we should do division first:
45÷5=9
We now have multiplication:
3x3=9
Now we have A and S for addition and subtraction
We don't have addition so we'll do subtraction:
9-9=0
The final answer is 0.
Hope this helps! :)

Answer
Find out the what is the value of x when y = 8 .
To prove
As given
The variables y and x have a proportional relationship.
y = kx
Where k is the constant of proportionality.
As y = 5 when x = 4
Put in the above
5 = 4k
Now find out the value of x , when y = 8
x= 6.5
Therefore when y = 8 than x = 6.4
For (A.) Get a common denominator, 40/12 - 9/12 = 31/12 or (2 and 7/12)
For (B.) Get a common denominator, 24/15 - 10/15 = 14/15 (Simplified)
For (C.) Get a common denominator, 51/30 - 25/30 = 26/30 or (13/15)
For (D.) Get a common denominator, 14/6 - 9/6 = 5/6 (Simplified)
Hope this helps!
