32-2x < 18
32 - 2x < 18
32-2x < 18
2x-5 is twice a number decreased by 5.
60 - 2n
the number is negative two.
Either 2*(n-4) = 2n - 8 or 2n - 4 It depends on whether the "twice" operates on "the number decreased by 4" or "the number".
three times a number decreased by eleven
Half of 18 is 9 and 5+4 = 9 so the number is 5
If you have a number x, then twice that number is 2*x and so the expression means 42 - 2*x
twice nine = eighteen
If: x+18 = 2x Then: x = 18
It is 5n - 8 <= 2n + 10
Two twenty-seven times or twenty-seven twice, three eighteen times or eighteen thrice, and six nine times or nine six times.
35-2x<18 35<18+2x 35<2(9+x) 17.5<9+x 26.5<x
It's an example of converting something easy into something nearly impossible, and then expressing it obscurely. Behind the veil lies an almost trivial algebra exercise. Although the question doesn't ask for the solution to the exercise, here it is anyway, at no extra cost: -- The difference between (eight times a number) and (twice the number) is (six times the number). -- (Six times the number) is eighteen. -- (the number) is one-sixth of eighteen, or three.
Two twent-seven times or twenty-seven twice, three eighteen times or eighteen thrice, and six nine times or nine six times. Comprende amigo?
so the difference between twelve and -34 is 46. half of 46 is 23, That's your answer
12-2n= -72n = 19n = 9.5
20-2x=3x-10 if its relevant the solution is x=6
