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

We will end up with m = $35. To prove this, plug 35 into the m value as shown below:
, so the answer is $35 more is needed.
Answer: 36

1) 10n
10 points per game, times however many games she plays.
2) x-15=19
x=34 (b)
x=15+19
Answer:
11.57
Step-by-step explanation:
We have a simple formula to solve this:

where
SS is sum of squares
s^2 is the variance, and
n is the number of data points
We are given all the info to find out s^2. Hence,

<u>1 3/10 Because 4/5+2/10= 1 plus 6/20 [3/10] is 1 3/10</u>
