He added 8 to both sides. He did the write thing.
Answer:
Yes, <em>z</em> will be greater than <em>x.</em>
Step-by-step explanation:
Given expression is 
now let <em>y = 2 </em>and <em>x = 1</em>
Then, 
where
i.e. <em>3 > 1</em>
on simplifying the given expression in terms of y

now suppose if <em>x = 7 and z=3 </em>then,

which gives value of y in terms of negative integer which is not possible according to the given statement since y is a positive integer. Therefore, if y is a positive integer then z will be greater than x.

Volume of a rectangular prism is l*h*w
1.2*3*4.5= 16.2
The answer is 16.2 cubic inches
A 4 digit addends could have a 5 digit sum because of the rule of regrouping.
Regrouping is a situation where carrying and borrowing is involves. So let’s have an example
8999
<span>+5678
</span>14677
so in this example, we added 8999 to 5678.
9+8 = 17, so we bring down 7 and carry 1
9 + 7 = 16 + 1 = 17 , so again we bring down 7 carry 1
9 + 6 = 15 + 1 = 16, bring down 6 carry 1
8+5 = 13 + 1 =14, since this is our last number, bring down 14..
=> 14, 677
