3x2 + 33x + 54 =3(x2 + 11x + 18) = 3(x + 9)(x + 2)
-9x+6y = 54 6y = 9x+54 y = 1.5x+9 slope = 1.5
15 + 14 + 14 + 11 + 2x + x = 75 Collect like terms 54 + 3x = 75 Subtract 54 3x = 21 Divide by 3 x = 7 ■
x=-9 15 + x = 6x + 60 x = 6x + 45 -5x = 45 x = -9 15 + (-9) = (6 * (-9)) + 60 15 - 9 = -54 + 60 6 = 60 - 54 6 = 6 There is no answer because, 15+x=6x+60 -15 -15 x=6x+45 Which is imposible because "x" can't equal itself times six plus forty-five.
9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
An equivalent expression to 54 plus 18x would be 18x + 54, as addition is commutative and the order of the terms can be rearranged without changing the value of the expression. Additionally, this expression can be simplified further by factoring out the common factor of 18 to get 18(x + 3). This final expression represents the original expression in a more simplified form.
51 × 14 = 5/4 54
It is the same as 54 plus 36 and both expressions add to 90
39x-6
18(2 + 3)
9 This expression can be simplified to: 9x
It is: 18(2+3) or simply as 90
It is 3*(54n + 1.8)
If you mean 5x+4x = 54 then the value of x is 6
a = 15.
