When the sum of an unknown number z and twenty-two is divided by the same unknown number, the quotient is twelve. What is the unknown number?
Answers
Applying the definition of quotient and creating an equation, the value of the unknown number is: z = 2.
What is Quotient?
Quotient is the result you get when two numbers are divided with each other.
Thus:
Unknown number = z
Sum of z and 22 is: z + 22
(z + 22)/z = 12 (quotient)
Solve to find the value of z
z + 22 = 12z
22 = 12z - z
22 = 11z
22/11 = z
z = 2
Therefore, applying the definition of quotient and creating an equation, the value of the unknown number is: z = 2.

22=12z-z
22=11z
z=22/11=2

10x-6y= -18
10x-25y=20
subtract equation 2 from equation 1 and the x's cancel:
10x-6y= -18
10x-25y=20
19y= -38
y= -2
substitute y= -2 into either of the original equations to get x= -3

-2 * -4 = ?
A negative times a negative equals a positive value.
-2*-4 = 8
12 - 8 = ?
12-8 = 4
Because 4+8 = 12
Final answer: 4
= 12-(2*4)
= 12- 8
= 4
The final answer is 4~

The equivalent ratio is
? : ? : 5
In the first ratio, look at the number in the same position as the 5 in the second ratio and compare it to the other 2 numbers. 80 is 10 times 8, and 40 is 5 times 8. Bring that same ratio down to the equivalent ratio...
5 x 10 = 50
5 x 5 = 25
The equivalent ratio is
25:50:5
The 8 on the first row is proportional to the 5 on the second row. For them to get 5 on the second row they multiplied the 8 by (5/8). I found that out by dividing the second number which was 8 by the first number which was 5.
So, 8 × (5/8) = 5. Since everything is proportional, we can multiply (5/8) to the other numbers on the first row to find out their numbers on the second row.
40 * (5/8) = 25
80 * (5/8) = 50
Those are the new numbers. If you have any questions then leave a comment. Good luck!
