Question

Consider the inequality 2y > 18.8.

Which of the following values make this inequality true? Select all that apply.

8.2
9.4
11
12.5
10.6

Answer 1

To solve this, We need to solve the equation with each given value of y

y = 8.2

`\sf \: 2y > 18.8 \\ \sf \: 2 * 8.2 > 18.8 \\ \sf16.4 > 18.8 \\ \boxed{ \tt \: false}`

y = 9.4

`\sf \: 2y > 18.8 \\ \sf \: 2 * 9.4 > 18.8 \\ \sf18.8 > 18.8 \\ \boxed{ \tt \: false}`

y = 11

`\sf \: 2y > 18.8 \\ \sf \: 2 * 11 > 18.8 \\ \sf22 > 18.8 \\ \boxed{ \tt \: true}`

y = 12.5

`\sf \: 2y > 18.8 \\ \sf \: 2 * 12.5 > 18.8 \\ \sf25> 18.8 \\ \boxed{ \tt \: true}`

y = 10.6

`\sf \: 2y > 18.8 \\ \sf \: 2 * 10.6> 18.8 \\ \sf21.2> 18.8 \\ \boxed{ \tt \: true}`

• Thus, Options C, D and E are correct!!~
