Question

If t < 5 which statement must be true ?

A ) 5t > 25

B) 5t > 50 )

C) t + 5 < 10

D ) - 5 - t < 10

Answer 1

The correct answer is C

Answer 2

The answer is C because if u plug in -100 as ‘t’ it is less than 10 and if you plug in 4 for ‘t’, it is also less than 10.

Another way to do this is solve for ‘t’ in each equation
So, for answer C if you move 5 to the other side you get t<5 (which matches the original inequality)
