A number line with a closed circle on 9 and shading to the left

Step-by-step explanation:

we have

$2(x+1)\geq 20$

Solve for x

$2x+2\geq 20$

$2x\geq 20-2$

$2x\geq 18$

$x\geq 18/2$

$x\geq 9$

The solution is the interval ----> [9,∞)

All real numbers greater than or equal to 9

A number line with a closed circle on 9 and shading to the right

Step-by-step explanation:

38.5 ÷ 0.5 = 77

77 x 0.5 = 38.5

(think of 5 x 7)

0.5 x 70 = 35 (3.5 left)

0.5 x 7 = 3.5 (0 left)

70 + 7 = 77
