(x + 2x + 3x) - 8 = 106x - 8 = 10Add 8 to each side:6x = 18Divide each side by 6:x = 3
6x + 7 < 3x + 106x - 3x
let accountants monthly income before raise in income be x then x + 6x\100 = 3460 106x/100 =3460 x = 3264.15 therefore accountants monthly income before raise was 3264.15
It is: 110x-2 simplified
Algebraically with X = numbers.X + (X + 1) = - 1052X + 1 = - 1052X = - 106X = - 53===========solution set
6x/2 = 106x = 10 x 2 (when taking the 2 to the RHS it is multiplied over because of the division on the LHS)6x = 20x = 20/6 (when taking the 6 to the RHS it id divided over because of the multiplication on the LHS)x = 4================================================================================Here, let me try:6x/2 = 10Reduce the fraction on the left to lowest terms.Divide numerator and denominator by 2:3x = 10Divide each side of the equation by 3:x = 10/3x = 31/3
(x + 2x + 3x) - 8 = 106x - 8 = 10Add 8 to each side:6x = 18Divide each side by 6:x = 3
6x + 7 < 3x + 106x - 3x
let accountants monthly income before raise in income be x then x + 6x\100 = 3460 106x/100 =3460 x = 3264.15 therefore accountants monthly income before raise was 3264.15
x + (x + 1) + (x + 2) + (x + 3) = 1424x + 6 = 142x = 3434 + 35 + 36 + 37 = 1425x+106x+157x+218x+289x+3610x+4511x+5512x+6613x+7814x+9115x+10516x+12017x+136There is only one sequence of consequent numbers that their sum is 142. Four consequent numbers.
The nth term is given by: t{n} = (-3x⁴ + 30x³ - 105x² + 106x + 388)/4 for n = 1, 2, 3, 4. Alternatively, your teacher may be expecting a much simpler (also valid) solution: Each term is obtained by subtracting 11 from the previous term: t{n+1} = t{n} - 11 Which means that t0 = t1 + 11 = 104 + 11 = 115 → t{n} = 115 - 11x for n = 1, 2, 3, 4 That formula is NOT valid for any other value of n The first formula gives t1 = 104, t2 = 93, t3 = 82, t4 = 71 and gives t5 = 42, continuing with -41, -232, -603, -1244, -2263,... The second formula gives t1 = 104, t2 = 93, t3 = 82, t4 = 71 (the same first 4 terms) but gives t5 = 60 and continues with 49, 38, 27, 16, 5, ...
