Step-by-step explanation:

1. 5z - 4 = 21

5z = 21 + 4

5z = 25

z = 25/5

z = 5

2. w/9 + 2 = 3

w/9 = 3 - 2

w/9 = 1

w = 1 x 9

w = 9

I really really really need help
Akimi4 [234]

So basically it seems that you can just give any value to a and b as long as the statement given is true. 4 & 5 can work for the part of the problem.

a = 4; b = 5

Plugged in:

4 + 1 = 5  (b > a; 5 > 4)

Therefore the statement is true. This is proof that it is.

Part B is asking when can the statement be false and what numbers prove that if possible.

It is possible for there to be values for a and b in which the relationship given turns false. For example, a = 4 and b = 3 makes the statement false since 4 + 1 doesn't equal 3 and 3 is not greater than its a-value of 4.

Hope this helps!
