Answer:
6-2x=10
Step-by-step explanation:
6-2x=10 is the answer.
Six less than means 6-
Twice a number means 2 and the unknown value "x" or it can also be "y"(it can be any letter since it is an unknown value) but we usually use "x" in this case.
When we are given "twice a number" in a sentence it means that that number is unknown.
Less than twice a number means -2x
Less than thrice a number means -3x
So,
six less (6-)
than twice a number (2x)
is 10 (=10)

WILL GIVE BRAINLIEST FOR THE RIGHT ANSWER!!
Answer:
19 gram
Step-by-step explanation:
Formula of mass left after ionising: [tex]\frac{M}{2^{n} }[/tex] where M is original mass and n is half lives.
Using the equation:
[tex]\frac{150}{2^{3} }[/tex] → 18.75
Therefore, 18.75 g left after ionising.
∵ If rounded to nearest gram then 19 gram.
What is the median weekly earnings of workers in the occupations listed for
2010?
Answer:
$971
Step-by-step explanation:
To find the median value, place the numbers in value order (from lowest to highest) then find the middle:
So putting the weekly earnings for 2010 in value order:
501, 900, 971, 977, 1071
So the middle value is 971. Therefore, the median = $971

In the given figure , ∆ABC , ∆ABD and ∆ADC are right angled triangles . Therefore here we can use the Pythagoras theorem , as ,
[tex]\longrightarrow[/tex] base² + perpendicular² = hypotenuse ² .
• In ∆ABD , we have ;
[tex]\longrightarrow[/tex] AB² + BD² = AD²
[tex]\longrightarrow[/tex] AB² + x² = 10²
[tex]\longrightarrow[/tex] AB² = 10² - x²
[tex]\longrightarrow[/tex] AB² = 100 - x²
[tex]\rule{200}2[/tex]
• Again in ∆ADC , we have ;
[tex]\longrightarrow[/tex] AC² + AD² = CD²
[tex]\longrightarrow[/tex] AC² = 20² - 10²
[tex]\longrightarrow[/tex] AC² = 400 - 100
[tex]\longrightarrow[/tex] AC² = 300
[tex]\rule{200}2[/tex]
Again in ∆ABC , we have ,
[tex]\longrightarrow[/tex] AC² = AB² + BC²
Substituting the values from above ,
[tex]\longrightarrow[/tex] 300 = 100-x² + (20-x)²
[tex]\longrightarrow[/tex] 300 = 100 - x² + 400 + x² - 40x
[tex]\longrightarrow[/tex] 40x = 500 - 300
[tex]\longrightarrow[/tex] 40x = 200
[tex]\longrightarrow[/tex] x = 200/40
[tex]\longrightarrow[/tex] x = 5

of Jafar's money. How much must Jafar give Jack so that both will have the same amount?
Answer:
50 dollars.
Step-by-step explanation:
Jack has 5/9 of Jafar's money, meaning he has 125 dollars. To have the same amount of money as each other, Jafar needs to balance this out. If he gives jack 50 dollars, both of them will have 175 dollars. Hope this helps you out! Mind giving me brainliest? :)
The amount of money Jafar must give Jack so they would have the same amount of money is $100.
How much should Jafar give Jack?The first step is to determine the amount that Jack has. In order to determine this amount, multiply 5/9 by $225.
5/9 x 225 = $125
Now, subtract $125 from $225
$225 - $125 = $100

What is 14.853 oz rounded to the nearest ounce?
Answer:
15 oz.
Step-by-step explanation:
Rounding to the nearest ounce:
14.853
Rounding notes:
If the number one place to the right of the rounding number is greater than 5, the number increases by 1.
If the number one place to the right of the rounding number is less than 5, the number stays the same and anything to the right of the rounding number changes to 0.
Work:
4 represents the 'ounces' place value.
To identify the rounding of 4, we need to determine if the value 8 is greater than 5, or less than 5.
8 > 5, meaning 4 increases to 5.
New rounded number = 15 oz.

Answer:
There are integers that are not rational numbers is false
There are whole numbers that are not rational numbers is false
There are integers that are not whole numbers is true
All rational numbers are integers is false
Step-by-step explanation:
Integers are whole numbers, or numbers that aren't fractions. For example, 1 and 2 are integers, while 5/2 isn't. Integers will always be rational, as rational means that it can be represented as a fraction and the integer 2 can be represented as 2/1 as can 4/2.
Whole numbers are just positive integers.
Not all integers are whole numbers though, since negative integers would not fit the definition of whole numbers (whole numbers have to be positive)
All rational numbers are integers is false, as rational numbers include fractions such as -3/7 or 2/5, which don't cover integers.

Answer:
5. [tex]\frac{2}{8}[/tex]
6. [tex]\frac{10}{12}[/tex]
7. [tex]\frac{11}{20}[/tex]
Step-by-step explanation:
5. [tex]\frac{1}{2} - (\frac{1}{8} +\frac{1}{8} )\\[/tex] = [tex]\frac{2}{8}[/tex]
Step 1: Solve for the fractions in the parentheses.
[tex]\frac{1}{8} +\frac{1}{8}[/tex]
This will be easy because they both have the same denominator.
= [tex]\frac{2}{8}[/tex]
Now we have:
[tex]\frac{1}{2} -\frac{2}{8}[/tex] =
Find the common denominator and change the numerator accordingly:
[tex]\frac{4}{8} -\frac{2}{8} = \frac{2}{8}[/tex]
6. [tex]\frac{3}{4} +(\frac{1}{4} -\frac{1}{6} )[/tex]
Step 1: Solve for the fractions inside the parentheses
Find the Common Denominator of both and change the numerators accordingly
[tex]\frac{1}{4} -\frac{1}{6} = \frac{3}{12} -\frac{2}{12}[/tex]
Then just subtract them
[tex]\frac{1}{12}[/tex]
Now we have:
[tex]\frac{3}{4} +\frac{1}{12}[/tex]
Find the common denominator:
[tex]\frac{9}{12} + \frac{1}{12}[/tex]
Then just add them
[tex]\frac{10}{12}[/tex]
7. [tex](\frac{1}{2} +\frac{3}{20} )-\frac{2}{20}[/tex]
Step 1: Solve the fractions in the parentheses
[tex]\frac{1}{2} +\frac{3}{20} =\frac{10}{20} +\frac{3}{20}[/tex]
Then solve
[tex]\frac{10}{20} +\frac{3}{20} =\frac{13}{20}[/tex]
Now we have
[tex]\frac{13}{20} -\frac{2}{20}[/tex]
Subtract
= [tex]\frac{11}{20}[/tex]
