Solve each of the following equations for xx using the same technique as was used in the Opening Exercise.
devlian [24]

Answer:

The solve of this equation is X = 4,06

Step-by-step explanation:

To solve this formula:

2 ( X² - 16) = 1

You must use the distributive law of multiplication, thus:

2X² - (16×2) = 1

2X² - 32 = 1

2X² = 1 + 32

X² = 33/2

X² = 16,5

X = √16,5

X ≈ 4,06

Thus, the solution of this equation is:

<em>X ≈ 4,06</em>

You have 1 case of soap bars and there are 150 bars in a case. You use 300 bars of soap per day. How many cases do you need to o
diamong [38]
<span><u><em>Answer:</em></u>
14 cases

<u><em>Explanation:</em></u>
<u>First, we will need to find the number of cases needed per day:</u>
We know that one case includes 150 bars and that the daily consumption is 300 bars. To know the number of cases needed daily, we will use cross multiplication as follows:
1 case .............> 150 bars
?? cases .........> 300 bars
number of cases needed daily = </span>\frac{300*1}{150}<span>
number of cases needed daily = 2 cases

<u>Then, we will get the number of cases needed weekly (7 days):</u>
We know that 2 cases are needed daily. To know the number of cases needed weekly (7 days), we will simply use cross multiplication as follows:
1 day .............> 2 cases
7 days ...........> ?? cases
number of cases needed weekly = </span>\frac{7*2}{1}<span>
number of cases needed weekly = 14 cases

Hope this helps :)</span>
