What is absolute value and why is it always positive?
Answer:
Step-by-step explanation:
An absolute value is the distance a number is from 0 on the number line. So, regardless if it is a negative or a positive number, the distance from that number to 0 will always be positive. For example, -5 is 5 units away from 0, and 5 is also 5 units from zero. They have the same absolute value, even though one is negative and the other is positive.
Answer:
You can describe absolute value as a number's (Negative or positive) distance from zero.
Step-by-step explanation:
Say you have 4 and -4. 4's absolute value is four because it is four number units away from zero. -4 is a negative number but its absolute value would still be positive four because it is still four number units away from zero even though those number units are negative.

Find an expression which represents the sum of (10x - 4y) and (4x -8y) in simplest terms.
Answer:
14x - 12y
Step-by-step explanation:
Let's write the sum:
(10x - 4y) + (4x -8y)
Because we're only doing addition and subtractaction, we can drop the parentheses that aren't preceded by a minus sign, they don't change the order.
10x - 4y + 4x - 8y
as long as we don't change the sign preceding each component, we can reorder as we wish
10x + 4x - 4y - 8y
(10x + 4x) - (4y + 8y)
note that because we added a parenthesis preceded by a - the sign inside changed.
We perform additions inside of the parentheses:
10x + 4x = 14x
4y + 8y = 12y
and we arrive at the final result:
14x - 12y

Fred spent half of his allowance on a game at Target. Then he earned an extra $20 by mowing his grandparents’ lawn. After he did this, he had $30 left. Write an equation to find what Fred's allowance is.
Use X as a variable
The equation to find what Fred's allowance is will be 0.5x + 20 = 30
How to compute the equation?Let the variables be x.
From the information, Fred spent half of his allowance on a game at Target. Then he earned an extra $20 by mowing his grandparents’ lawn. After he did this, he had $30 left.
This will be:
(1/2 × x) + 20 = 30
0.5x + 20 = 30
Therefore, the equation to find what Fred's allowance is will be 0.5x + 20 = 30

Books are on sale for $7. Peter has $30 dollars in his wallet. How many books can he buy?( interpret the remainder)
Answer:
He can buy 4 books with 2 dollars remaining
Step-by-step explanation:
30/7 = 4 R2
Answer: 4 books.
Explanation: First you divide $30 by 7, and you get 4 and 2/7 (2/7 as the remainder) left over. So you can't have 4 and 2/7 books, it has to be a whole number.
Therefore, he can buy 4 books. I hope this helped!

Step-by-step explanation:
-¼ ( x + 2) + 5 = - x
( this is a multi-step equation)
The value of x after simplfication of equation -¼ ( x + 2) + 5 = - x is -6.
Consider the equation,
( - 1 / 4 ) × ( x + 2 ) + 5 = - x
Now,
( - x / 4 ) + ( - 2 / 4 ) + 5 = - x
( - x / 4 ) - ( 1 / 2 ) + 5 = - x
Now, LCM of 2 and 1 is 2.
Therefore,
( - x / 4 ) + [ ( 10 - 1 ) / 2 ] = - x
( - x / 4 ) + ( 9 / 2 ) = - x
Adding x on both sides of the equation.
( - x / 4 ) + x + ( 9 / 2 ) = - x + x
Subtracting ( 9 / 2 ) from each side of the equation,
( - x / 4 ) + x + ( 9 / 2 ) - ( 9 / 2 ) = ( - 9 / 2)
( - x / 4 ) + x = ( - 9 / 2 )
LCM of 4 and 1 is 4
[ ( - x + 4x ) / 4 ] = ( - 9 / 2 )
( 3x / 4 ) = ( - 9 / 2 )
By cross multiplying,
2 × 3x = - 9 × 4
6x = - 36
Dividing each side of the equation by 6.
( 6x / 6 ) = ( - 36 / 6 )
x = - 6

Triangle BCD has the following side lengths: BC = 60, CD = 50
Triangle RST has the following side lengths: RS = 11x-4, ST = 70
What is the value of x? (put just the number in the first box)
What is the length of side RS? (put just the number in the second box)
The value of x is 11 and the length of side RS is 117
How to determine the value of x?The given parameters are
BC = 60 and CD = 50
RS = 11x - 4 and ST = 70
Express as a ratio
BC : CD = RS : ST
So, we have
60 : 50 = 11x - 4 : 70
Express as fraction
So, we have
60/50 = (11x - 4)/70
Cross multiply
So, we have
50 * (11x - 4) = 70 * 60
Divide both sides by 50
So, we have
11x - 4 = 84
This gives
11x = 88
Divide both sides by 11
So, we have
x = 11
Substitute x = 11 in RS = 11x - 4
RS = 11 x 11 - 4
Evaluate the product and the sum
RS = 117
Hence, the value of x is 11 and the length of side RS is 117
