$\frac{4 + (x + 1)}{x + 1} = \frac{16}{12} \\ \\ \frac{5 + x}{x + 1} = \frac{16}{12} \\ \\ 12(5 + x) = 16(x + 1) \\ 60 + 12x = 16x + 16 \\ 4x = 44 \\ x = 11$

Write the inequality for x that is shown on this line. Can you answer these 3 questions:

dexar [7]

Answer: a) x < 3

b) 3, 4, 5, 6

c) x > 6

Step-by-step explanation:

First you need to understand the symbols:

< means less than (represented by an open dot, left arrow)

≤ means less than or equal to (represented by a closed dot, left arrow)

> means greater than (represented by an open dot, right arrow)

≥ means greater than or equal to (represented by a closed dot, right arrow)

a) We have a closed dot and a left arrow so we need to use <

We write this inequality as: x < 3

b) y is BETWEEN 2 and 6 (not including 2 but including 6)

2 3 4 5 6

c) 3x + 7 > x + 19

2x + 7 > 19 subtracted x from both sides

2x > 12 subtracted 7 from both sides

x > 6 divided both sides by 2
