In math, "over" and "/" and "÷" mean the same thing. The expression you have written is
... 7/12/5/9 = 7/540
It seems possible you may want the ratio of two fractions to be simplified. Perhaps you intend ...
... (7/12)/(5/9) = (7/12)×(9/5) = (7×9)/(12×5) = 63/60
... = 21/20 = 1 1/20

Dividing by anything is the same as multiplying by its reciprocal. This is a convenient fact when dividing by a fraction.
Answer:
y = -x + 2
Step-by-step explanation:
— 5х – 4у = -8
-4y = 4x - 8
4y = -4x + 8
y = -x + 2
-3x-14 should be the answer
Supposing we begin with n=1, the first few terms of this arith sequence are
5, 1, -3, -7, and so on. 4 is the common difference.
In order to find out what 36x + 9 is equivalent to,, we must factor out 9 from the expression. Once we do this you will find that this expression is equivalent to 9(4x + 1),, or option E.
Next we will look at the expression 9(4x -1). In order for us to find out the equivalent to this expression,, we must first multiply each term in the parenthesis by 9.
9 × 4x - 9
Now calculate the product
36x - 9
This means that the equivalent for this expression is 36x - 9,, or option A.
Lastly,, we will look at the final expression given which is 4(9x + 2). The first step for finding the equivalent of this expression is to multiply the numbers in the first parenthesis together.
(36x) + (4 × 2)
Now multiply the numbers in the second parenthesis together.
(36x) + 8
Remove the parenthesis
36x + 8
Now factor out 4 from the expression to get your final answer.
4(9x + 2)
This means that the last expression is equivalent to 4(9x + 2),, or option C.
