X+9=27, so to move the nine over to the other side of the equal sign, x=27-9, x=18
Answer:
see attachment
Step-by-step explanation:
It is convenient to use a spreadsheet for this purpose.
The first row of numbers is constant at $45, as there is no daily charge associated with that payment method.
The second row of numbers uses the formula ...
cost = $12 + $4×(number of days)
The third row of numbers uses the formula ...
cost = $6×(number of days)
___
Of course, you can use these formulas to fill in the numbers by hand. For example, for 15 days, the charges are ...
- Early Pay: $45 (no calculation necessary)
- Deposit Plus: $12 + $4×15 = $12 +60 = $72
- Daily Pay: $6×15 = $90
Answer:
2
Step-by-step explanation:
<em>Add 1.5 to both sides:</em>
5/2x-1.5+1.5=3.5+1.5
5/2x=5
<em>Multiply both sides by 2/5</em>
(2/5)*(5/2x)=(2/5)*(5)
Answer:
(a) 4 possible outcomes
(b) Not possible, testing stops upon finding the bad battery,
Step-by-step explanation:
Let G denote a good battery and B denote a bad battery.
Whenever a bad battery is found, the batteries stop being tested.
(a) The outcomes for this experiment are:
B
GB
GGB
GGGB
There are 4 possible outcomes.
(b) The outcome GBGG is not possible since testing stops upon finding the bad battery, the outcome in this case would be GB.
