Question 2 ONLY

Butoxors [25]

In triangle ABC angle c = 180-78-40 = 62 degrees

For the triangles to be congruent angle z must equal angle C

Solve for x:

2x + 8 = 62

Subtract 8 from both sides:

2x = 54

Divide both sides by 2:

X = 27

Now we k ow x has to equal 27 to be concurrent so we can answer the 3 questions.

A museum has a 1/2 ounce piece of a precious metal. When the museum first received the piece, it had a value of $90. Its value h

Alex777 [14]

The current value of the precious metal is $144/oz

-First, you'd want to determine the original value per ounce since that's what the final unit being asked for is.

- Since the original value of the half ounce piece is given, this first step is fairly simple. You just double ninety.

- We now know that the metal was worth $180/oz when the museum first received it.

- We need to determine the current price of the metal now that is has had a twenty percent loss of value.

- My favorite way to factor in 20% is simply to divide by five since it's a lot more simple than finding the ratio of x$/1%

- $180/5=$36

- Thirty-six dollars is the price drop over the course of the museum possessing the precious metal.

- You now take $180-$36=$144

Alexandra has $2.10 worth of nickels and dimes. She has a total of 27 nickels and dimes all together. Determine the number of ni

OlgaM077 [116]

Answer:the number of nickels is 12

the the number of dimes is 15

Step-by-step explanation:

Let x represent the the number of nickels.

Let y represent the the number of dimes.

A nickel is worth 5 cents = 5/100 = $0.05

A dime is worth 10 cents = 10/100 = $0.1

Alexandra has $2.10 worth of nickels and dimes. This means that

0.05x + 0.1y = 2.10 - - - - - - - - - -1

She has a total of 27 nickels and dimes all together. This means that

x + y = 27

Substituting x = 27 - y into equation 1, it becomes

0.05(27 - y) + 0.1y = 2.10

1.35 - 0.05y + 0.1y = 2.1

- 0.05y + 0.1y = 2.1 - 1.35

0.05y = 0.75

y = 0.75/0.05 = 15

Substituting y = 15 into x = 27 - y, it becomes

x = 27 - 15 = 12
