1. \frac{n}{4}

2. -2+5n or 5n-2

3. (12s)+150 where s=number of students

4. 3(32)+1(53)=96+53=159 per hour, so 159h

9. √105 is irrational, -4 is an integer, 4/3 is a rational number, order is -4,3/4, √105

10. 3²=9, 4²=16, so between 3 and 4, but closer to 4, so √14≈4

11. that is the associative property, it deals with moving parentahees around

12. 2(6.25)+1(5.50)+2(2.75)=2(6.25+2.75)+1(5.50)=2(9)+5.5=18+5.5=23.5

13. yes, because they are both 2 less than 3 times of a number

14. maybe 18 times 3, so (4²+2) times 3=54

If a certain number is added to the numerator of 29/62 and twice the number is subtracted from the denominator, the result is eq
Rasek [7]

Answer:

Correct option: (d) 7.

Step-by-step explanation:

Let the number be denoted by <em>x</em>.

The original fraction is: \frac{29}{62}

Add <em>x</em> to the numerator, i.e. 29 and subtract 2<em>x</em> from the denominator, i.e. 62.

The new fraction is: \frac{29+x}{62-2x}

Now equate the new fraction to \frac{3}{4} and solve for <em>x</em> as follows:

     \frac{29+x}{62-2x}=\frac{3}{4}

4(29+x)=3(62-2x)\\116+4x=186-6x\\4x+6x=186-116\\10x=70\\x=7

The value of <em>x</em> is 7.

Thus, the correct option is (d).
