a language arts test is worth 100 points there is a total of 26 questions . there are spelling word questions that ae worth 2 po
natka813 [3]

10 question of spelling words and 16 questions of vocabulary are present

<em><u>Solution:</u></em>

Let "x" be the number of spelling word questions

Let "y" be the number of vocabulary word question

<em><u>There is a total of 26 questions. Therefore, we get</u></em>

number of spelling word questions + number of vocabulary word question = 26

x + y = 26 --------- eqn 1

<em><u>There are spelling word questions that worth 2 points each and vocabulary word question worth 5 points each</u></em>

The language arts test is worth 100 points

Therefore, we frame a equation as:

number of spelling word questions x 2 + number of vocabulary word question x 5 = 100

x \times 2 + y \times 5 = 100

2x + 5y = 100 --------- eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

From eqn 1,

x = 26 - y ------- eqn 3

<em><u>Substitute eqn 3 in eqn 2</u></em>

2(26 - y) + 5y = 100

52 - 2y + 5y = 100

3y = 100 - 52

3y = 48

<h3>y = 16</h3>

<em><u>Substitute y = 16 in eqn 3</u></em>

x = 26 - 16

<h3>x = 10</h3>

Thus 10 question of spelling words and 16 questions of vocabulary are present

In 1975 1000 tons of coal was manufactured. It is 10% greater in 1976 and 5% less in 77. What is the final about of coal in 1977
Digiron [165]
In 1975 it was 1000tons, ok, well, in 1976 it went up by 10%, how much is a 10% increase?

\bf \begin{array}{ccllll}&#10;coal&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;1000&100\\&#10;x&100+10&#10;\end{array}\implies \cfrac{1000}{x}=\cfrac{100}{100+10}\implies \cfrac{1000\cdot 110}{100}=x&#10;\\\\\\&#10;1100=x

well, in 1976 it was 1100 tons then, and in 1977 it went down by 5% of 1100, well, if we take 1100 to be the 100%, then what is a 5% decrease?

\bf \begin{array}{ccllll}&#10;coal&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;1100&100\\&#10;x&100-5&#10;\end{array}\implies \cfrac{1100}{x}=\cfrac{100}{100-5}\implies \cfrac{1100\cdot 95}{100}=x
