Which inequality is true when R = 4.6
Nookie1986 [14]

Answer:

A. 3R > 14

Step-by-step explanation:

Here R = 4.6

Now we have to check each options and find which is true.

3R > 14

Dividing both sides by 3, we get

R > 14/3

R > 4.67

Which is true.

All other options are not true.

R + 32 >

R > -32 is not true.

R - 12 < -8

R < +4 is not true.

R/3 < 1

R < 3 is not true.

Hope this will help you.
