Question

Can anyone help me please

Answer 1

Answer:

Step-by-step explanation:

We need to check each u value to say if each one is correct...

8 $\leq$ u - 27

when u = 33

8 $\leq$ 33 - 27

8 $\leq$ 6

and it's true!

So, 33 is solution

when u = 39

8 $\leq$ 39 - 27

8 $\leq$ 12

It isn't true. No solution!

When u = 31

8 $\leq$ 31 - 27

8 $\leq$ 4

It's true and it also is a solution.

when u = 35

8 $\leq$ 35 - 27

8 $\leq$ 8

it's true and it also is a solution.
