17ab
Only if b is greater than 1 and less than 2 will 12b be greater than 12 and less than 24. If b is 1 or less, 12b will be less than or equal to 12 If b is 2 or more, 12b will be greater than or equal to 24.
12b - 5 = 15b + 5 subtract 12b from both sides 12b - 12b - 5 = 15b - 12b + 5 - 5 = 3b + 5 subtract 5 from each side - 5 - 5 = 3b + 5 - 5 - 10 = 3b divide both sides integers by 3 - 10/3 = (3/3)b - 10/3 = b ---------------------check in original equation ( change whole numbers to fractions of common denominations ) 12(-10/3) - 15/3 = 15(-10/3) + 15/3 - 120/3 - 15/3 = - 150/3 + 15/3 - 45 = - 45 checks
It is 20a - 5b - 9.
The number is 84.Assign the digits in the number the letters a and b.GIVEN: a + b = 12GIVEN: a = 2bSolve for b, then solve for a.2b + b = 123b = 12b = 4a = 2(4) = 8
12b
It is the same as: 12b-24
A=12b+3 A=-2b--4
4(3b+2)
b = 6
(b+8)(b+4)
(b + 8)(b + 4)
(b + 8)(b + 4)
The LCM is 36bc^3.
4(3b - 5) < -31 + 12b12b - 20 < -31 + 12b, this is not true because -20 > - 31, so that the solution for the given inequality does not exist.
6a -12b + 30 = 6 (a - 2b + 5)
24 = 48 - 12b subtract 48 from each side -24 = -12b divide both sides by -12 2 = b
