Answer:

3.9

Step-by-step explanation:

cost = 24.40

subtract the cost of beads from the total cost.

24.40-8.8=15.6

divide that by four because there are 4 necklaces

15.6/4=3.9

What is the converse of the linear pairs theorem
marysya [2.9K]
The converse of a logicalstatement is a s tatement formed by reversing the parts of the statement.

For example, the logical statement "A implies B" has a converse of "B implies A"

The linear pairs theorem states that "<span>if two angles form a linear pair, then they are supplementary".</span>

The converse of the linear pairs theorem is therefore, "if two angles are suplementary, then they form a linear pair".

Helpppppppppp please
eduard

You know b=-6 and since you know this, you can plug -6 in for b.

This would become 4(-6) + 6 divided by 6.

You can then multiply 4 and -6 together,

-24 + 6 / 6

You can then add -24 and 6 together,

-18/6

You can then divide -18 by 6,

-18/6=-3

-3 is your final answer

a2 = -2(4) - 1
a2 = -9

a3 = -2(a2) - 1
a3 = -2(9) - 1
a3 = -19

Example:
Aleonysh [2.5K]

Answer:

AB // CD and AD // BC, then ABCD is a parallelogram

Step-by-step explanation:

Step 2: Show AD // BC

A = (-3 , 3) and D = (0 , 0)

Find the slope of AD

m_{AD}=\frac{0-3}{0--3}=\frac{-3}{3}=-1

B = (2 , 5) and C = (5 , 2)

m_{BC}=\frac{2-5}{5-2}=\frac{-3}{3}=-1

The slope of AD = the slope of BC

So AD // BC because they have the same slope

Step 3:

Each two opposite sides are parallel in quadrilateral ABCD

So the quadrilateral is a parallelogram
