Solve for x A) 42 B) 40 C) 45 D) 38

Mathematics
1 answer:
alexgriva [62]3 years ago
3 0

Answer:

x = 40

Step-by-step explanation:

Using similarity theorem, we have the following:

\frac{24}{24 - 15} = \frac{x}{x - 25}

Solve for x

\frac{24}{9} = \frac{x}{x - 25}

Cross multiply

24(x - 25) = x(9)

24x - 600 = 9x

Subtract 24x from each side

- 600 = 9x - 24x

- 600 = -15x

Divide both sides by -15

40 = x

x = 40

<h3>Answer:  60</h3>

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

Explanation:

Multiply the two values to get 4*15 = 60

Then divide by the GCF 1 to get 60/1 = 60. The GCF being 1 means the result hasn't changed.

------

Another example would be: "Find the LCM of 6 and 8". We would first do 6*8 = 48, then divide by the GCF 2 to get 48/2 = 24. The LCM of 6 and 8 is 24.

Lisa and Bill made 60 magnets for a craft fair. They sold about 55% of the magnets. Lisa says they sold about 30 magnets. Bill s
koban [17]

Answer:

Step-by-step explanation:

The total number of magnets that Lisa and Bill made for the craft fair is 60.

They sold about 55% of the magnets. The number of magnets that they sold would be about

55/100 × 60 = 0.55 × 60 = 33

If Lisa says that they sold about 30 magnets, she is correct because if we round off 33 to the nearest ten, it would be 30 magnets.

If Bill says that they sold about 36 magnets, he is wrong because if we round off 36 to the nearest ten, it would be 40 magnets.

Explain why the graphing calculator cannot be used to solve or approximate solutions to all polynomial equations.
Lelu [443]
Let's put it this way:  If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>

Step-by-step explanation:

1. Turn problem into 20 + 0.10x = 50

2. Subtract 20 from both sides to get 0.10x = 30

3. Divide both sides by 0.10 to get x = 300
