Answer:
Absolute value;
The non-negative value of x(in your case -19) without regard to its sign.
Basically how far in distance x(in your case -19) is away from 0.
|–19| = 19
Answer:
19
Step-by-step explanation:
Given the following question:
When dealing with absolute value we need to understand that all negatives in between "| |" are changed into positives. See absolute value (| |) as if its a car wash, and negatives are dirty cars.
In this case...

x + 3=12 need help now someone please help me
Answer:
x = 9
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3 from both sides of the equation:
x + 3 (-3) = 12 (-3)
x = 12 - 3
x = 9
x = 9 is your answer.

simplify (5x-7) (2x+3) (7x-8)
Answer:
70x³ - 73x² - 155x + 168
Step-by-step explanation:
Given
(5x - 7)(2x + 3)(7x - 8) ← expand the first pair of factors using FOIL
= (10x² + x - 21)(7x - 8)
Each term in the second factor is multiplied by each term in the first factor, that is
10x² (7x - 8) + x(7x - 8) - 21(7x - 8) ← distribute the 3 parenthesis
= 70x³ - 80x² + 7x² - 8x - 147x + 168 ← collect like terms
= 70x³ - 73x² - 155x + 168

Step-by-step explanation:
Molly bought a pair of gloves and a skirt. The gloves cost £4. She sold the gloves and skirt for a total of £48. She made 100% profit on the cost of the gloves, 20% profit on the total cost. Work out her percentage profit on the cost of the skirt. Give your answer to 1 decimal place.
Answer:
Profit % = 111.1 %
Step-by-step explanation:
Cost of glove = £4
Sales price of glove and skirt = £48
100% profits on the cost of the glove
20% profit on the total cost
Profit on the total cost = 20% = 0.20
Total cost + 0.20 total cost = Sale value
1.20 * total cost = 48
Total cost = 48 / 1.20
Total cost = 40
Cost of the skirt = Total cost - cost of the gloves
Cost of the skirt = 40 - 4
= 36
Price of the skirt = total value - price of the gloves
Total value = £48
100% of £4 = 100/100 * £4
= £4
Profits + cost of glove = $8
Amount remaining = £48 - £8
= £40
Profit percentage on the skirt = price of the skirt / cost of the skirt
= 40 / 36 * 100
= 1.1111 * 100
Profit % = 111.1 %

HELP PLEASE 15 POINTS ILL GIVE YOU COOKIE
Answer:
75?
Step-by-step explanation:
Isnt the total of the line suppose to equal 180*? if thats the case then the first angle 101* is 11 over the 90* mark meaning that you take 11 from the other side which would be 90-11 and that leave you with 79 but since the problem says +4 you would take 4 from 79 leaving you with 75. You would work backwards on the problem so the whole thing equals 180*

Anna had a solid wooden dowel with a length of 12 inches and a diameter of 1 inch, as shown below. She cut a two-inch portion out of the dowel as indicated. What was the volume, to the nearest tenth of a cubic inch, of the portion of the dowel that Anna cut out?
Answer:
Volume of the portion = 1.6 cubic inches
Step-by-step explanation:
Since, wooden dowel is in the shape of a cylinder,
Formula to be used to find the volume of the part Anna has cut from the dowel will be,
Volume = πr²h
Where r = radius of the cylinder or part of the wooden dowel
h = length of the portion
By substituting the values in the formula,
Volume = π(0.5)²(2)
= 0.5π
= 1.57 in³ ≈ 1.6 cubic inch
Therefore, volume of the portion will be 1.6 in³.
