Someone help me with #19 pleasee!!

Answer 1

For problems like these, it's very helpful for looking at key words. 'How many more' suggests that one value is greater than the other by a certain amount, which means subtraction. Let's do the same for this equation.

If 165 is m greater than 130, then this means $130 + m = 165$.

This will also mean that m is 130 less than 165. To solve this, isolate the variable and subtract 130 from both sides:

$130 - 130 + m = 165 - 130$

We will end up with m = $35. To prove this, plug 35 into the m value as shown below:

$130 + (35) = 165$, so the answer is $35 more is needed.
