Answer:

Step-by-step explanation:
As with any "solve for ..." problem, you undo what is done to the variable of interest. Here, what is done is ...
- A is added
- the sum is multiplied by Y
You "undo" these operations in reverse order (from the bottom of the list up). To undo multiplication, you multiply by the reciprocal:

To undo the addition of A, add the opposite of A:

Answer:
6x + 4 = 40
Step-by-step explanation:
6 boxes
x = number of pencils per box
therefore Sam had 6x and received 4 more
It is generally useful to use the formula. The procedure is to substitute the given values for the variables in the formula, then do the arithmetic.
... A = (1/2)r²·θ . . . . r is the radius, θ is the central angle in radians
Put the numbers in ...
... A = (1/2)(4 in)²·(π/3)
... A = 8π/3 in² ≈ 8.37758 in²
The answer would be 5/55 because if you subtract 32 from 37 you would end up with 5 and because the denominator was the same you keep the denominator the same.
