I guess you mean: What number when you subtract 20, gives 40 as the answer?
x - 20 = 40.
Add 20 to both sides: x - 20 + 20 = 40 + 20
x = 60
A number "m" plus 40 equals 60. Therefore, 60 minus 40 equals m. m therefore equals 20.
The numbers are: -2 and -20
20 is the GCF. The LCM is 40.
The next number in the sequence 5, 10, 20, 40 is 80. Each number in the sequence is multiplied by 2 to get the next number. So, 40 multiplied by 2 equals 80.
Of course!
A number "m" plus 40 equals 60. Therefore, 60 minus 40 equals m. m therefore equals 20.
The numbers are: -2 and -20
20 is the GCF. The LCM is 40.
It is: 20*40 = 800
The next number in the sequence 5, 10, 20, 40 is 80. Each number in the sequence is multiplied by 2 to get the next number. So, 40 multiplied by 2 equals 80.
20% of 40= 20% * 40= 0.2 * 40= 8
20 times 2 = 40
Percentages seem to confuse a lot of people but they really shouldn't. A percentage is simply a fraction. 40% is written as .40 or 4/10. So let's say your given number is 20. To add 40% to 20 you multiply 20 by 1.4 and the answer is 28. The reason you multiply by 1 is you are ADDING 40% so you want the original number you started with. 20 times 1 equals 20. So we have our original number in our answer. The .4 comes from 40%. 20 times .4 equals 8. So 20 plus 8 equal 28.
Of course!
Oh, dude, you're hitting me with some math here. So, like, if you wanna know what times 20 equals 800, you just divide 800 by 20, and boom, you get 40. It's like math magic, but without the cool cape.
2/x =16/20 16x = 40 x = 2.5
40/10 = 20/a 4= 20/a 20/4 = a a= 5
