The associative property of addition is being demonstrated here. The parenthesis are moved around to "associate" or "group" the values into two different pairs.

Note: the associative property of multiplication is very similar and it is
a*(b*c) = (a*b)*c<span />

Please explain urgent! Brainly to anyone who can answer!
Wittaler [7]

Answer:

  • JK ≈ 6.86 units

Step-by-step explanation:

According to the diagram MK is the angle bisector of  ∠LMJ in the triangle LMJ.

Use angle bisector theorem, which states:

  • <em>an angle bisector of an angle of a triangle divides the opposite side into two parts that are proportional to the other two sides of the triangle.</em>

<em />

Applied to the given triangle, the ratios are:

  • LK/JK = LM/JM

Use segment addition postulate and substitute known values to get:

  • (LJ - JK)/JK = LM/JM
  • (14 - JK)/JK = 50/48
  • 50JK = 48(14 - JK)
  • 50JK = 672 - 48JK
  • 50JK + 48JK = 672
  • 98JK = 672
  • JK = 672/98
  • JK = 6.86 (rounded)

Annual fixed costs for a product are $75,000. The product itself sells for $6 and it costs $2 in variable costs to make each pro
rusak2 [61]

Given

Annual fixed costs for a product are $75,000.

The product i sells for $6

it costs $2 in variable costs to make each product.

the variable cost per unit goes up to $2.50

find out how many units will the annual break-even point for the product change .

To proof

FORMULA

Break even = Fixed cost ÷  Contribution margin per unit

where

Contribution margin per unit = sale price - variable price

Take two cases

Case first

fixed costs for a product =  $75,000

product itself sells =  $6

variable costs  = $2

put all the value in the above equation

we get

Contribution margin per unit = 6 - 2

                                               = 4

Break even (say B1 ) = \frac{75000}{4}

                                        = 18750 units

CASE SECOND

 the variable cost per unit goes up to $2.50

put value inthe formula

Contribution margin per unit = 6 - 2.50

                                               = 3.5

Break even (say B2 ) = \frac{75000}{3.5}

we get

Breakeven (sayB2) = 21428.6 unit

change in the break even product = B2- B1

                                                         = 21428.6 - 18750

                                                        =  2678.6 unit

Hence proved

Elvate 5-3(X-1) when X=7
USPshnik [31]

If x = 7 we just substitute all the x's by seven, so our equation stays like this:

5 - 3(7 - 1)


Now we solve it:

5 - 3(7 - 1) =

5 - 3(6) =

5 - 18 =

-13


Hope it helped,
