which of the following is the solution to |10x|>-2

Answer: -10c-20

Step-by-step explanation:

Equation: -8c - 17 - 2c - 3

First, you factor -8c+17+ -2c+ -3

Then, combine like terms: (-8c+ -2c)+(-17+ -3)

Answer: -10c - 20

Answer:

Step-by-step explanation:

Mean: 8 + 7 + 8.5 + 6.5 + 5 + 11 + 15 + 8 + 8 + 7 + 7.5 + 6.5 + 8 + 14 + 12 = 132 / 15 = 8.8

Median: You have to arrange the numbers first in ascending order.

5, 6.5, 6.5, 7, 7, 7.5, 8, 8, 8, 8, 8.5, 11, 12, 14, 15

The median is 8 because that is the middle value/number.

Mean Absolute Deviation:

Get the average/mean (1), find the deviation (2) to get MAD (3).

Step #1 Mean = 8.8

Step #2 To get the deviation, you subtract the mean from the values given.

8 - 8.8 = -0.8

7 - 8.8 = -1.8

8.5 - 8.8 = -0.3

6.5 - 8.8 = -2.3

5 - 8.8 = -3.8

11 - 8.8 = 2.2

15 - 8.8 = 6.2

8 - 8.8 = -0.8

8 - 8.8 = -0.8

7 - 8.8 = -1.8

7.5 - 8.8 = -1.3

6.5 - 8.8 = -2.3

8 - 8.8 = -0.8

14 - 8.8 = 5.2

12 - 8.8 = 3.2

Step #3 Get the summation from step #2, and get its average. Disregard the negative signs.

0.8 + 1.8 + 0.3 + 2.3 + 3.8 + 2.2 + 6.2 + 0.8 + 0.8 + 1.8 + 1.3 + 2.3 + 0.8 + 5.2 + 3.2 = 33.6 / 15 = 2.24 is the Mean Asolute Deviation

Median Absolute Deviation:

Get the median (1) and subtract it from the values (2). Get the median of the new values (3)

Step #1 Median = 8

Step #2

8 - 8 = 0

7 - 8 = -1

8.5 - 8 = 0.5

6.5 - 8 = -1.5

5 - 8 = -3

11 - 8 = 3

15 - 8 = 7

8 - 8 = 0

8 - 8 = 0

7 - 8 = -1

7.5 - 8 = -0.5

6.5 - 8 = -1.5

8 - 8 = 0

14 - 8 = 6

12 - 8 = 4

Step #3 Arrange the numbers in ascending order.

-3, -1.5, -1.5, -1, -1, -0.5, 0, 0, 0, 0, 0.5, 3, 4, 6, 7

The Median Absolute Deviation is 0 since it is the middle value/number.

It is important that you calculate this by yourself in case I did some careless mistakes.

Percentage increase is 30% increase.

The value of the percentage increase would be 30 percent.

Used the concept of the percentage that states,

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating the hundredth part of any quantity is called a percentage.

Given that,

The price of a toy usually costing £50 is increased to £65.

Hence, the increased price is,

£65 - £50 = £15

So, the percentage increase would be,

[tex]P = \dfrac{\£15}{\£50} \times 100\%[/tex]

[tex]P = \dfrac{1500}{50}\%[/tex]

[tex]P = 30\%[/tex]

Number of calories in 8 ounces of orange juice = 100

Number of calories in 1 ounce of juice = [tex]\frac{100}{8}[/tex]

Number of calories in 4 ounces of juice = [tex]\frac{100}{8}*4=50[/tex] calories

Number of calories in 8 ounces of pineapple juice = 140

Number of calories in 1 ounce of juice = [tex]\frac{140}{8}[/tex]

Number of calories in 4 ounces of pineapple juice =

[tex]\frac{140}{8}*4=70[/tex] calories

Now the mixture has 50+70 = 120 calories in 8 ounce.

So, 1 ounce of mixture has = [tex]\frac{120}{8}= 15[/tex] calories.

To find the number of calories in Tia's juice mixture, we set up an equation based on the given information. Solving the equation, we find that there are 4 calories in each fluid ounce of Tia's juice mixture.

To find the number of calories in Tia's juice mixture, we can set up an equation based on the information provided. Let's say x represents the number of calories in each fluid ounce of orange juice, and y represents the number of calories in each fluid ounce of pineapple juice. Since Tia mixed 4 fluid ounces of each juice, the total number of calories in the mixture would be 4x + 4y. We know that there are 100 calories in 8 fluid ounces of orange juice and 140 calories in 8 fluid ounces of pineapple juice. We can set up the equation:

100 calories = (8/4)x

140 calories = (8/4)y

Simplifying the equations, we have:

25x = 100

35y = 140

Solving for x and y, we find:

x = 4

y = 4

Therefore, there are 4 calories in each fluid ounce of Tia's juice mixture.

Step-by-step explanation:

Keira spends approximately $119.12 on food.

To find the fraction of Keira's total spending on petrol, we need to determine the total amount she spent on all items and then calculate the fraction spent on petrol.

Total amount spent on all items (T): We'll use algebra to find the total amount Keira spent.

Fraction spent on other items and clothes: Given Keira spends 1/9 of the money on other items and 1/5 of the money on clothes, we'll find the combined fraction spent on other items and clothes.

Fraction spent on petrol: Subtract the fraction spent on other items and clothes from 1 to find the fraction spent on petrol.

Amount spent on food: Subtract the amounts spent on petrol, other items, and clothes from the total amount to find the amount spent on food.

Total amount spent on all items (T): Let T represent the total amount spent.

Fraction spent on other items and clothes:

[tex]\[ \frac{1}{9} + \frac{1}{5} = \frac{5}{45} + \frac{9}{45} = \frac{14}{45} \][/tex]

Fraction spent on petrol:

[tex]\[ 1 - \frac{14}{45} = \frac{31}{45} \][/tex]

Amount spent on food:

  [tex]\[ \text{Amount spent on food} = T - (45 + \frac{1}{9} \times T + \frac{1}{5} \times T) \] \[ \text{Amount spent on food} = T - (45 + \frac{14}{45} \times T) \] \[ \text{Amount spent on food} = \frac{31}{45} \times T \][/tex]

Now, to find the value of T, we solve the equation:

[tex]\[ \frac{31}{45} \times T = 45 + \frac{14}{45} \times T \]\[ \frac{31}{45} \times T - \frac{14}{45} \times T = 45 \]\[ \frac{17}{45} \times T = 45 \]\[ T = \frac{45 \times 45}{17} \]\[ T \approx 119.12 \][/tex]

So, Keira spends approximately $119.12 on food.

The complete question is:

Keira goes shopping at a supermarket. the pie chart below shows information about the money she spends on petrol, clothes, food and other items. what fraction does she spend on petrol? if keira spends $45 on petrol, 1 9 of the money on other items and 1 5 of the money on clothes. how much money does she spend on food? $

Answer: 1 and 3/5

Step-by-step explanation: The common denominator is 10. So, in order for everything to have a denominator of 10, we need to multiply a few things.

4 x 2 = 8

5 x 2 = 10

1 x 5 = 5

2 x 5 = 10

With that out of the way, we can finally move on to figure out the answer.

8/10 + 3/10 + 5/10 = 16/10. The question asks to write as a mixed number, if necessary. And it is. So:

10 goes into 16 once, with 6 left over, so 1 and 6/10. the fraction can be reduced, so we do that. Because 2 goes into 6 (3 times), and 2 goes into 10 (5 times), that leaves us with a final answer of 1 and 3/5.

Final answer:

To add 4/5, 3/10, and 1/2, first find a common denominator, which is 10. Convert the fractions to 8/10, 3/10, and 5/10, add them to get 16/10, which simplifies to 1 6/10, and then further simplify to the mixed number 1 3/5.

Explanation:

To add the fractions 4/5, 3/10, and 1/2, we need a common denominator. The least common multiple of the denominators 5, 10, and 2 is 10. Thus, we convert each fraction to an equivalent fraction with a denominator of 10. The converted fractions are 8/10, 3/10, and 5/10.

Next, we add the numerators: 8 + 3 + 5 = 16. The sum of the fractions is 16/10, which simplifies to 1 6/10 by dividing 16 by 10. Finally, we can simplify the fraction 6/10 to 3/5 because both the numerator and the denominator can be divided by 2. Therefore, our final answer is 1 3/5.
