12 divided by 2 x the absolute value of 1.3 minus 2.16
yaroslaw [1]

The value of the expression (12/2)×| 1.3 - 2.16 | is  5.16  .

The Absolute Value of a number means writing the number without the negative sign .

For Example : the absolute value of -2 is |-2| = 2

In the question ,

an expression in words is given as "12 divided by 2 x the absolute value of 1.3 minus 2.16 "

the above expression in numbers can be represented by

= (12/2)×| 1.3 - 2.16 |

= 6 × | 1.3 - 2.16 |

= 6 × |-0.86|

= 6 × 0.86           .... because |-0.86| = 0.86

= 5.16

Therefore , The value of the expression (12/2)×| 1.3 - 2.16 | is  5.16  .

The given question is incomplete , the complete question is

Find the value of the expression " 12 divided by 2 x the absolute value of 1.3 minus 2.16 "  ?

I don’t understand this assignment!!
Rashid [163]

Answer:

Equation of the Line: y = 1.25x + 5

Equation in Standard Form: 5x - 4y = -20

Step-by-step explanation:

y = mx + b

\frac{17.5 - 22.5}{10 - 14} = \frac{-5}{-4} = \frac{5}{4} or 1.25

y = 1.25x + 5

Ax + By = C  (A must be positive, and no fractions or decimals)

y = 1.25x + 5

-1.25x + y = 5

times -4

5x - 4y = -20
