The quotient of 4 and 5 is 4 divided by 5, which equals 0.8. The product of 6 and z is 6z. When the quotient of 4 and 5 (0.8) is added to the product of 6 and z (6z), the expression becomes 0.8 + 6z.

75/(z + 2) = 25 z = 1
If you think about it, it makes sense. when you divide a whole number (call that number X) by any number less than it(call that Z), the quotient (answer) is smaller than the first number. For example, 10/2=5, 12/4=3. Also, the lower the Z number is (ignoring if it were 1), the higher the quotient is. Therefore, since fractions are lower than 0, the quotient will be higher than the X number.

Well, 'x' is equal to 'z'. Back in plane geometry, there was a mantra that said: "Two quantities equal to the same quantity are equal to each other." This question is an example of that mantra. So for Example: If x = 10 Then x = y (making y = 10) y = z (making z = 10) therefore z is the same.
Q and Z
y=84-72=12 z=84-52=32 x=84-12-32=40

75/(z + 2) = 25 z = 1
9z-5z = 30+z 3z = 30 z = 10

First divide by 100. Then multiply by 180. Now you add 32 along with that. You will get the temperature in Fahrenheit. So in general F = C/100 * 180 + 32. So 72+32 = 104 Fahrenheit. F and C would be the same when? Let them be z. Then 0.8 z = -32. So z = -40. Hence -40 C is equal to -40 F. It is so interesting.
