65 - 20 = 45
45 = 3/4
45/3 = 15
15 x 4 = 60
Another way, if you were required to state it algebraically:
.75X + 20 = 65
.75X = 45
X = 60
x+8+x/5 = 20 x = 10
20+2x
20% of 200 is 20/100 * 200 = 40 So 200 increased by 20% is 240.
Suppose the number is N.Then (N + 4)*2 = N + 20that is, 2N + 8 = N + 20subtracting N from both sides gives: N + 8 = 20subtracting 8 from both sides gives: N = 12.
Well, isn't that just a happy little math problem! To find 50% of 20, you simply divide 20 by 2, which gives you 10. Then, you add that 10 back to the original 20, giving you a total of 30. So, 20 increased by 50% is 30.
x+8+x/5 = 20 x = 10
113 + 20 = 133.
20+2x
47 Impossible problem!
20% of 200 is 20/100 * 200 = 40 So 200 increased by 20% is 240.
It is 92
(108 and 1/3)
There will be an overall increase in the first number.
Suppose the number is N.Then (N + 4)*2 = N + 20that is, 2N + 8 = N + 20subtracting N from both sides gives: N + 8 = 20subtracting 8 from both sides gives: N = 12.
what is the mathematical phrase for the verbal phrase the sum of a number and three
To find 20 percent of a number, multiply the number by 0.2. In this instance, 0.2 x 3000 = 600. Therefore, 20 percent of 3000 is equal to 600.
Oh, dude, let me break it down for you. So, if we start with the number x and increase it by 20%, we get 1.20x. And we know that 1.20x is equal to 240. So, to find x, we just divide 240 by 1.20, giving us 200. So, the original number was 200. Easy peasy, like basic math, man.
