Answer:

a-6b+4c

Step-by-step explanation:

a-{5b-[a-(3b-2c)+c-(a-2b-c)]}

a-{5b-[a-1(3b-2c)+c-1(a-2b-c)]}

a-{5b-[a+(-3b+2c)+c+(-a+2b+c)]}

a-{5b-[a-3b+2c+c-a+2b+c]}

a-{5b-[-b+4c]}

a-{5b+[b-4c]}

a-{5b+b-4c}

a-{6b-4c}

a+{-6b+4c}

a-6b+4c

Price of an item = X dollars

Discount = 20%

Amount of discount = 20% of Price of item

Amount of discount =  

Price of item after discount = Price of item - Amount of discount

Please help. Full explanation if you can.

392 boots. If you divide everything into "sets" of an unknown amount, there are 5 more "sets" of boots than sandals, also known as the 245 boots. So if you divide 245 by 5, you'll get the number of items in a "set". Then just multiply by 8 from the 8:3 ratio. If you check it, it will come out to 392 boots to 147 sandals, which I think is ridiculous since sandals are supposed to come in pairs so  you should never have a odd number. But anyway, 392 - 147 = 245

In a random sample, 10 students were asked to compute the distance they travel one way to school to the nearest tenth of a mile.
elixir [45]

Answer:

Mean = 3.12, Variance = 3.324, Standard deviation = 1.8232

Step-by-step explanation:

Total number of students = 10 students.

Given data, 1.1, 5.2, 3.6, 5.0, 4.8, 1.8, 2.2, 5.2, 1.5, 0.8

To find the mean, at first we have to take the sum of all given data and then divide with the number of students.

Let the data is X, = 1.1, + 5.2, + 3.6, + 5.0, + 4.8, + 1.8, + 2.2, + 5.2, + 1.5, + 0.8 = 31.2

Mean = 31.2 / 10 = 3.12

\text{Standard deviation, S} = \sqrt{\frac{\sum x^{2} - \left [ (\sum x)^{2}/n \right ]}{n-1}} \\S = 1.8232 \\\rm The \ Variance = S^{2} = 3.324

6 4/5+5 3/10 adding and subtracting mixed number
lawyer [7]

Too add mixed numbers, first convert them to improper fractions:

34/5 + 53/10

Next, find a common denominator, which in this case is 10.

Convert 34/5 so that it has a denominator of 10 by multiplying the ENTIRE fraction by 2: 68/10

68/10 + 53/10 = 121/10

You can either give your answer in the form of an improper fraction: 121/10, or a mixed number 12 1/10
