The answer is 48
illustration:
833 is a multiple of 49 which is more than 832
the multiple which is immediately less than 833 is 784
so the difference that must be subtracted is 832- 784 = 48
If a number is divisible by 5, it either ends in a 0 or a 5. Since this doesn't end in either, we know it isn't divisible by 5. We should find the next lowest number that is divisible by 5. Since 155 ends in a five, we know it is divisible by 5, and because this is the closest number below 157 that is divisible by 155, we know this is the greatest number of students that could be put equally into 5 classes. Alternatively, we can divide 157 by 5, and we get 31.4. Since we only want something that divides evenly by 5, we round this down to 31, then multiply by 5 to get 155.
from another wikianswers page: say that 'a' is rational, and that 'b' is irrational. assume that a + b equals a rational number, called c. so a + b = c subtract a from both sides. you get b = c - a. but c - a is a rational number subtracted from a rational number, which should equal another rational number. However, b is an irrational number in our equation, so our assumption that a + b equals a rational number must be wrong.
I assume the question should be y = -2x + 5? The equation of a line that is parallel to that line is any line that begins 7 = -2x ... after the -2x any number may be added or subtracted. Parallel lines have the same slope. In the original equation, the slope is -2.
Here are some consecutive odd integers. All must follow this form: x+x+2+x+2=3x + 6 6 is divisible by 3. So is 3x. If you add two integers that are divisible by 3, it is still divisible by three. The question is not about odd integers, but consecutive integers. This should be x + x+1 + x+2 =3x+3 A bit simpler would be the three in a row : x-1, x, x+1 which add up to 3x which can be divided by 3.
In order to subtract a fraction from a whole number one should take the bottom number from a fraction, for example if the fraction was 1 10th then the bottom number would be 10. The whole number should be divided by the bottom number, then the top number equivalent removed from the total whole number and this will leave the fraction number once the fraction has been subtracted.
It is: 16 because 18448-16 = 18432 and 18432/48 = 384
which least number should be subtracted from 1000 so that 30 divides the difference exactly
27836/56 gives 497 and 4 as quotient and remainder Dividend- remainder =27836-4 = 27832 which is divisible by 56. So the least no that to be subracted is 4
It would help if you could insert the relevant numbers in the copy/paste!
32575/9 gives 3619 as quotient 4 as remainder. now from 32575 subtract the remainder 4 that is 32571. this is divisible by 9. 4 should be
832/48 gives 17 as quotient and 16 as remainder. Dividend-remainder=divisor*quotient 832-16 = 48*17 which is 816 that is divisible by 48. So 16 to be subracted.
2,789/10= 2,78.9. Just move the decimal place over one spot. So, if the answer has to be a whole number, not a fraction, then please subtract 9 from the number to get 2,780. No fraction.
Dividend-remainder=divisor *quotient 9660/76 gives 127 quotient and 8 remainder 9660-8=76*127 9652 so 8 must be subracted from 9660 ans is 8
To determine if a number is divisible by 6, it must be divisible by both 2 and 3. To determine if a number is divisible by 2, it should be even - in other words, it should end with 0, 2, 4, 6, or 8. To determine if a number is divisible by 3, the sum of its digits should be divisible by 3. 54,132 is an even number, so it is divisible by 2. 5 + 4 + 1 + 3 + 2 = 15, which is divisible by 3, so 54,132 is divisible by 3. Since 54,132 is divisible by both 2 and 3, it is divisible by 6.
10056รท23 gives 437 as quotient and 5 as remainder. Dividend-remainder= divisor× quotient so 10056-5=23×437 gives 10051.our question is least no should be added to 10056 which is divisible by 23. Check next possibility 23×438 gives 10074. Now 10056+18= 10074. Therefore 18 is the least number should be added to 10056 to get a number divisible by 23
the rule for divisibility by 9 is that the sum of all digits of the number should should be divisible by 9. So, 3+9+0+6+5= 23. To make is divisible by 9, we think of 27 (as the next number divisible by 9) and that means if we add 4 to any digit of the number, it will be divisible. 39069/9=4341
Since 1000 is a multiple of 40... the next lowest multiple is 960. Therefore you simply subtract 40 !
