Answer:

Expressions are not meant to be solved, they are more so to be evaluated and explained.. a visual differenceis that there is no equal sign or answer written, an equation is solved and has an equal answer. EXPR: (2 x 13) + 9 EQU: (19 x 12) + 3= 231

Tema [17]
The answer is A. 14h + 11d

because if you 3d and 8d it will give you 11d

the take 24h and subtract to 10h it will give you 14h

so when you write it you answer is 14h + 11d

Hope this helps! :)

Which of the following is the solution set of 18 - 3n + 2 = n + 20 - 4n?
exis [7]

The solution set of the equation is all reals ⇒ 3rd answer

Step-by-step explanation:

The solution set of an function is the set of all vales make the equation true. The equation has:

  • Solution if the left hand side is equal to the right hand side
  • No solution if the left hand side doesn't equal the right hand side

∵ The equation is 18 - 3n + 2 = n + 20 - 4n

- Add the like terms in each side

∴ (18 + 2) - 3n = (n - 4n) + 20

∴ 20 - 3n = -3n + 20

- Add 3n to both sides

∴ 20 = 20

In the equation of one variable, when we solve it if the variable is disappeared from the two sides, and the two sides of the equations are equal, then the variable can be any real numbers, if the two sides are not equal, then the variable couldn't be any value

∵ The the variable n is disappeared

∵ The left hand side = the right hand side

∴ n can be any real number

∴ The solution set of the equation is all real numbers

The solution set of the equation is all reals

The price of a stock had a change of –3 dollars. explain how you would use a number line to find the absolute value of –3.
Naya [18.7K]
Draw out a horizontal line. Place 0 at the center. Then place evenly spaced tick marks on either side of 0. Label the right side of tick marks as 1, 2, 3, ... moving from 0 and going to the right

Label the left side of tick marks -1, -2, -3, ... starting at 0 and moving left

The location -3 on the number line is exactly 3 units away from 0. We start at 0 and move to -3 by moving 3 spots to the left; or we start at -3 and move 3 units to the right to get to 0.

Therefore, the absolute value of -3 is 3
Absolute value on a number line is the distance a number is from 0
The distance is never negative
