Question

Identify if each number sentence is true or false? (show your work)

Answer 1

(27)

we are given

$5x+34$

we need to check for x=12

so, we can plug x=12

$5*12+34$

$60+34$

$94$

we know that 94 is always greater than 54

so, this is FALSE

(28)

$8.5\leq s-12$

we have to check at s=20.5

we can plug it

$8.5\leq 20.5-12$

$8.5\leq 8.5$

we know that

8.5 is equal to 8.5

so, this is TRUE..........Answer
