Please double check to ensure that y ou have copied the original problem correctly. x^2-x-12 x 2 − x − 12. What do you mean by -12 x 2? Perhaps you meant -12x^2?

Just suppose that you meant -12x^2. Then your expression becomes

x^2-x-12x^2 − x − 12 and this simplifies to -11x^2-2x -12. Not easy to factor!

So, once again, please ensure that you have copied down this problem exactly as it was given in your assignment.

What is the ratio for consonants to vowels,Vowels to total letters,and all letters to consonants

Studentka2010 [4]

Answers:

Ratio of consonants to vowels = 21:5
Ratio of vowels to total letters = 5:26
Ratio of all letters to consonants = 26:21

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

Explanation:

vowels = {a, e, i, o, u}

consonants = anything but a vowel (eg: the letter R)

There are 26 letters in the English alphabet. Five of which are vowels, so there are 26-5 = 21 consonants.

The ratio of consonants to vowels is 21:5

The order is important because the number of consonants must be listed first, simply because "consonants" is mentioned first in the phrasing "ratio of consonants to vowels". In other words, writing 5:21 would mean the ratio of vowels to consonants.

The ratio 21:5 cannot be reduced further since 21 and 5 have no factors in common (other than 1).

------------------------------

The other ratios will follow a similar idea as mentioned in the previous section.

To get the ratio of vowels to total letters, we list the number of vowels first (5) follow by the number of letters (26). A colon separates the two numbers to form the ratio 5:26

This ratio cannot be reduced further.

-------------------------------

Like in the previous sections, we'll glue together two numbers to form a ratio. In this case, we have 26 letters glued with 21 consonants to form the ratio 26:21 and this represents the ratio of total letters to consonants.

This ratio cannot be reduced further.

Solve for x. 2/3x−5=21 x = 39 x=52/3 x = 24 x=32/3

Finger [1]

2x/3 - 5 = 21

2x/3 = 26

2x = 78

x = 39
