Lamar made 6 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 6 necklaces was $43.80If the beads cost $3.80 for each necklace, how much did each pendant cost?

Step-by-step explanation:

5(x-3) = 0

5x-15=0

5x=15

x=15/5

x=3

i think you added the dot after 5 by mistake so yes this is how i could solve

Answer:

The total deposit amount is 225.

Step-by-step explanation:

Answer:

i=3/4

Step-by-step explanation:

Assuming that we are treating "i" as a variable and not the constant "i":

12+2i-i=9i+6

12+i=9i+6

12=8i+6

6=8i

8i=6

i=6/8

i=3/4

Therefore, the equation has only one real solution which is i=3/4

Answer:

6 units

Step-by-step explanation:

JK + KL = JL

3x + 5x-6 = 4x+2

8x-6 = 4x+2

subtract 4x from each side to get:

4x - 6 = 2

add 6 to each side to get:

4x = 8

x = 2

JK = 3x and x=2 so JK = (3)(2) or 6

The numerical length of JK = 6

What is Line Segment?

" A line segment is a line section that can link two points. "

We know that point K is divide line JL

Given that JL = 4x+2

                 KL = 5x-6

                JK = 3x

So,  Equation is JK+KL = JL

                           3x+5x-6 = 4x+2

                           8x-6 = 4x+2

                            8x-4x = 2+6

                            4x = 8

                              x = 8/4

                             x = 2

So , numerical length of JK = 3x

                                        JK = 3×2

                                         JK = 6

Hence , length of JK is 6

Answer:

  d.  AB = 54

Step-by-step explanation:

The triangle is isosceles, so AB = AC.

  (4x +6) = (5x -6)

  12 = x . . . . . . . . . . . . add 6-4x to both sides

Then the length of AB is ...

  AB = 4x +6 = 4(12) +6 = 48 +6

Part (a)

Refer to the diagram below to see the two triangles separated.

================================================

Part (b)

If the 3 meter portion is perpendicular to the horizontal portion, then the triangles are similar. We can prove this using the AA similarity theorem. One pair of angles would be the shared overlapping 25 degree angles. The other pair of congruent angles would be the two 90 degree angles. We only need two pairs of congruent angles to use AA. You could use three pairs (and the aptly named AAA theorem) but that's overkill in my book.

================================================

Part (c)

There are a few ways to approach this, but one way is shown below

y/3 = (8.4+6.6)/(6.6)

y/3 = 15/(6.6)

6.6y = 3*15 .......... cross multiply

6.6y = 45

y = 45/(6.6)

y = 6.81818 approximately

When rounding to one decimal place, we get y = 6.8

Answer:

36

Step-by-step explanation:

f * √g = k

12 * √64 = k

k = ± 96

g = k² / f² = (± 96)² / 16² = 36

Answer:

g = 36

Step-by-step explanation:

Given f is inversely proportional to [tex]\sqrt{g}[/tex] then the equation relating them is

f = [tex]\frac{k}{\sqrt{g} }[/tex] ← k is the constant of proportion

To find k use the condition when f = 12 , g = 64 , then

12 = [tex]\frac{k}{\sqrt{64} }[/tex] = [tex]\frac{k}{8}[/tex] ( multiply both sides by 8 )

96 = k

f = [tex]\frac{96}{\sqrt{g} }[/tex] ← equation of proportion

When f = 16 , then

16 = [tex]\frac{96}{\sqrt{g} }[/tex] ( multiply both sides by [tex]\sqrt{g}[/tex]

16 × [tex]\sqrt{g}[/tex] = 96 ( divide both sides by 16 )

[tex]\sqrt{g}[/tex] = 6 ( square both sides )

g = 6² = 36

Answer:

Answer:

-1, -4

Step-by-step explanation:

x + y = -5

x×y = 4

=>

x = -5 - y

=> (-5 - y) × y = 4

-5y - y² = 4

y² + 5y + 4 = 0

the solution for a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

a = 1

b = 5

c = 4

x = (-5 ± sqrt(25 - 16))/2 = (-5 ± 3)/2

=> x = -2/2 = -1 or x = -8/2 = -4

=> y = 4/-1 = -4 or y = 4/-4 = -1

since the sequence in an addition and multiplication does not make any difference, the two numbers are simply -1 and -4
