10 x 42x - 18 = 2082
musickatia [10]
Hey, I am able to help you today :)

Step 1 - Simplify:
420x^2 - 18 = 2082

Step 2 - Add 18 to both sides:
420x^2 = 2082 + 18

Step 3 - Simplify 2082 + 18 to 2100:
420x^2 = 2100

Step 4 - Divide both sides by 420:
x^2 = 2100/420

Step 5 - Simplify 2100/420 to 5
x^2 = 5

Step 6 - Simplify:
x = 5

Step 7 - Check your answer:
10 x 42 x 5 - 18 =2082

Hope this helps you today :)

ratelena [41]

Answer:

D. 24

Explanation:  

First you would need to find how many you need for one coat.

400 times 12 = 4,800

(That will give you a little extra paint)

Then just double 12 to get two coats and you would get D.

Have a nice day!

Hope this helped.

Cross multiply to get answer<br> x + 5/10 = 2x-3/15
Andreyy89

Once cross multiplied you end up with this:

15x+75=20x−30

Next subtract 20x from both sides.

15x+75−20x=20x−30−20x

−5x+75=−30 -----------> Answer

Now subtract 75 from both sides

−5x+75−75=−30−75

−5x=−105

Now divide by -5 on both sides.

-5/-5x = -105/-5

10 The collection of distinct vowel letters from the words PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS​
irina1246 [14]

The collection of distinct vowel letters from the words PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS​

The words' vowel letters are [A,,E,I,O,U].

A, E, I, O, U, Y, and, as we'll see, W are vowels, but let's go more precise now. They are symbols (letters) that represent a certain kind of spoken sound called a vowel. According to phoneticians, a vowel is a spoken sound that is made without severely limiting the airflow from the lungs.

The alphabet consists of 26 letters, five of which are vowels (a, e, I, o, and u). The other letters are consonants. A vowel is a sound made by opening the mouth and allowing air to escape without closing it or clearing the throat.
