Solve the following inequality. |3n-2|-2<1

disa [49]

Answer: $\frac{-1}{3}$ < n < $\frac{5}{3}$

Step-by-step explanation:

| 3n - 2 | - 2 < 1

+2 +2

| 3n - 2 | < 3

3n - 2 < 3 and 3n - 2 > -3

+2 +2 +2 +2

3n < 5 and 3n > -1

n < $\frac{5}{3}$ and n > $\frac{-1}{3}$

$\frac{-1}{3}$ < n < $\frac{5}{3}$

Interval Notation: $(\frac{-1}{3},$ $\frac{5}{3})$

Graph: $\frac{-1}{3}$ o--------------------o $\frac{5}{3}$

He counted 206 wheels and 170 pedals. How many bicycles and tricycles does he have.

noname [10]

Bicycle has 2 wheels and 2 pedals
tricycle has 3 wheels and 2 pedals

EQ 1 : 2b + 2t = 170 pedals

EQ 2: 2b +3t = 206 wheels

subtract EQ 1 from EQ 2

2b +3t = 206 - 2b + 2t = 170 = t=36

there were 36 tricycles

36 x 2 = 72 pedals

170 pedals - 72 = 98 pedals left
98/2 = 49 bicycles

36 Tricycles and 49 bicycles
