Given:

Package A

Birthday cards = 3

Thank you notes = 2

Costs = $18

 

Package B

Birthday cards = 8

Thank you notes = 6

Costs = $50

 

Required:

x = birthday card cost

y = thank you notes cost

 

Solution:

Package A:

18 = 3x + 2y

Package B:

50 = 8x + 6y

 

Second, add the two equations using elimination method.

 

To find y eliminate x;

[8 (18 = 3x + 2y)] + [-3 (50 = 8x + 6y)]

(144 = 24x + 16y) + [-150 = -24x + (-18y)]

-6 = -2y

Divide both sides with -2.

y = 3 thank you notes cost

Next, let us find x by substituting the value of y.

(18 = 3x + 2y) + (50 = 8x + 6y)

[18 = 3x + 2(3)] + [50 = 8x + 6(3)]

(18 = 3x + 6) + (50 = 8x + 18)

68 = 11x + 24

68 – 24 = 11x

44 = 11x

Divide both sides with 11.

X = 4 birthday card cost

Is slang considered a type of English?
zhuklara [117]
Well, most slang words that have been used for a long period of time have been added to the dictionary, but then again, some other slang words have not. So, it really depends on the word.
But, for a straightforward answer i would say yes, just because some slang words are in the dictionary.

<h3>What do prepositions mean ?</h3>

When used before a noun, pronoun, or noun phrase, a preposition expresses direction, time, place, location, spatial relationships, or the introduction of an object. Prepositions include the words such as "in," "at," "on," "of," and "to." English prepositions are frequently idiomatic.

Simple prepositions are short words we employ before nouns or pronouns to show how they relate to the noun in question. The two categories of simple prepositions are time and place. Simple, double, compound, participle, and phrase prepositions are the five different types of prepositions.
