How to do number a and d?help please​

Mathematics
1 answer:
suter [353]3 years ago
8 0

Answer:

a. Let's call the first number x which would make the other 2 numbers x + 2 and x + 4. Since they have a sum of 54 we can write:

x + x + 2 + x + 4 = 54

3x + 6 = 54

3x = 48

x = 16 so the numbers are 16, 18, 20.

d. We can write:

30 + x = 4(3 + x)

30 + x = 12 + 4x

18 = 3x

x = 6 years

At basketball practice you made 21 out of 80 shots. Which choice is closest to the percentage of shots you made?
love history [14]
Since this is a percentage, all you have to do is divide 21 from 80 and multiply that by 100
 21/80 = .2625 * 100 is 26.25

The answer closest to this is 25%, so the answer is 25%

Hope this helped! :D

Find the answer to zero point 73 repeating times square root of 147 end square root and select the correct answer below. Also, i
liubo4ka [24]

Answer:

\frac{511\,\,\sqrt{3} }{99}  which is an irrational number

Step-by-step explanation:

Recall that the repeating decimal 0.7373737373... can be written in fraction form as: \frac{73}{99}

Now, let's write the number 147 which is inside the square root in factor form to find if it has some perfect square factors:

147=7^2\,3

Then, 7 will be able to go outside the root when we compute the final product requested:

\frac{73}{99} \,*\,7\,\sqrt{3} =\frac{511\,\,\sqrt{3} }{99}

This is an irrational number due to the fact that it is the product of a rational number (quotient between 511 and 99) times the irrational number \sqrt{3}
