Absolute value is defined as the distance of a number from zero on a number line.
Since, the distance can never be negative, hence, absolute value can never be negative.
For example 1 is 1 away from the origin and -1 is also, 1 away from the origin.
Therefore, absolute value of both -1 and 1 is 1. Mathematically, we can write
|-1| =1
|1|=1
Therefore, the number 1 and -1 on the number line have an absolute value of 1.
The answer is 10/3
The explanation 2 1/3 cu of flour/ 3 1/2 dozen of cookies = X unknown cu. of flour/ 5 dozen cookies
Cross multiply
3 1/2 X = 5 (2 1/3) Change the mixed numbers into improper.
7/2 X = 5 ( 7/3) Solve for "X." Multiply both sides of equation by reciprocal of 7/2, which is 2/7
(2/7 (7/2)X = 5 (7/3)(2/7) X= 10/3 =Just divide 10 by 3. You should get a whole number
Answer: y = 3
Step-by-step explanation: You're given x, find y.
- -2(-3) + 3y = 12 (substitute in for x)
- 6 + 3y = 12 (multiply)
- 3y = 9 (divide both sides by 3)
- 3 = y
Answer:
x = - 3
Step-by-step explanation:
Given
12x + 7x = 5x - 42, that is
19x = 5x - 42 ( subtract 5x from both sides )
14x = - 42 ( divide both sides by 14 )
x = - 3
