In any division sum, such as 8 / 4 = 2, the number to be divided, in this instance, the 8, is the dividend.
x+8+x/5 = 20 x = 10
2 x 6 + 0 = 12 2 x 1 + 2 = 4 4 is not [divisible by] 8, so 60 is not divisible by 8. (The remainder when 60 is divided by 8 is 4). To test divisibility by 8: Add together the hundreds digit multiplied by 4, the tens digit multiplied by 2 and the units (ones) digit. If this sum is divisible by 8 so is the original number. (Otherwise the remainder of this sum divided by 8 is the remainder when the original number is divided by 8.) If you repeat this sum on the sum until a single digit remains, then if that digit is 8, the original number is divisible by 8 otherwise it gives the remainder when the original number is divided by 8 (except if the single digit is 9, in which case the remainder is 9 - 8 = 1).
Sum of 8 and 4 (8+4=12) is 12 Difference of 8 and 4 (8-4=4) is 4 So 12/4 is 3
x+8=20+12

In any division sum, such as 8 / 4 = 2, the number to be divided, in this instance, the 8, is the dividend.
The sum of 20 and -4 is +16, while the product of 4 and -2 is -8. The answer to the question is therefore -2.

x+8+x/5 = 20 x = 10
The expression "twice the quotient of 50 and the sum of a number y and 8" can be written mathematically as ( 2 \times \frac{50}{y + 8} ). This represents taking the sum of ( y ) and 8, finding the quotient of 50 divided by that sum, and then multiplying the result by 2.
2 x 6 + 0 = 12 2 x 1 + 2 = 4 4 is not [divisible by] 8, so 60 is not divisible by 8. (The remainder when 60 is divided by 8 is 4). To test divisibility by 8: Add together the hundreds digit multiplied by 4, the tens digit multiplied by 2 and the units (ones) digit. If this sum is divisible by 8 so is the original number.

Sum of 8 and 4 (8+4=12) is 12 Difference of 8 and 4 (8-4=4) is 4 So 12/4 is 3
It is 92
The given number is 20 (8 divided by 40 then times 100).
x+8=20+12
