Which number is a solution of the inequality?
padilas [110]

we know that

A number is an inequality solution if the number satisfies the inequality

<u>Part 1)</u> 10.6 < b

rewrite the inequality

b > 10.6

The answer Part 1) is the option D 14

Because  14 satisfies the inequality

14 > 10.6 -----> is true

<u>Part 2)</u> m > 7/12

The answer Part 2) is the option A 1

Because  1 satisfies the inequality

1 > 7/12 -----> is true

<u>Part 3)</u> 8< x(7-x)

we're going to verify every case

<u>case A)</u> For x=2

substitute the value of x in the inequality

8< 2(7-2)

8< 10 ------> is true

therefore

The number 2 is a solution

<u>case B)</u> For x=8

substitute the value of x in the inequality

8< 8(7-8)

8< -8 ------> is not true

therefore

The number 8 is not a solution

<u>case C)</u> For x=-1

substitute the value of x in the inequality

8< -1(7-(-1))

8< -8 ------> is not true

therefore

The number -1 is not a solution

<u>case D)</u> For x=0

substitute the value of x in the inequality

8< 0(7-0)

8< 0 ------> is not true

therefore

The number 0 is not a solution

therefore

The answer Part 3) is the option A 2
