Hey You!
32 / 8 = 4
4 × 7 = 28
20. ANSWER:

21. ANSWER:
Numerator;Denominator
22. ANSWER:
439 / 3 = 146.3333 repeat.
So, each individual computer costs more than each individual printer.
Simplify. Combine like terms
7y - 3y = 4y
-12 + 9 = -3
----------------------------------------------------------------------------------------------------------------
4y - 3 = 0
Isolate the y. Note the equal sign. What you do to one side, you do to the other side. Do the opposite of PEMDAS.
4y - 3 (+3) = 0 (+3)
4y = 3
4y/4 = 3/4
y = 3/4
-----------------------------------------------------------------------------------------------------------------
y = 3/4 is your answer

Answer:
63
Step-by-step explanation:
Reversing the digits changes the value by a factor of 9 times the difference in the digit values. Here, this means the digits differ by 27/9 = 3. If one digit is double the other, the higher digit is 2×3 = 6.
The number is 63.
_____
If you like, you can work through the algebra of it. Let the original number have tens digit x and ones digit y.
original number value = 10x +y
reversed number value = 10y +x
difference of values = 27 = (10x +y) -(10y +x) = 9(x -y)
The tens digit is twice the ones digit, so we have ...
x = 2y
Substituting in the difference equation, we have ...
27 = 9(x -y)
3 = (2y -y) = y . . . . . divide by 9, substitute for x
x = 2(3) = 6
The number is 10x+y = 63.
