Answer 1

Answer:

1) $5r + 2 < s$

2) $12t + 6s < 960$

3) $p - q > 30$

Step-by-step explanation:

1) Length of a ruler = r

Height of Shiela = s

According to the question ,

5 times the length of a ruler increased by 2 .

⇒ $5r + 2$

Also , 5r + 2 is less than height of Shiela.

Hence , the linear inequality is ⇒ $5r + 2 < s$

2) Let the cost of each t-shirt be 't' & cost of each short be 's'.

⇒ Cost of dozen of t-shirts = 12t and Cost of half a dozen shorts = 6s

According to the question ,

12t & 6s is not greater than Php 960.

Hence the linear inequality is ⇒ $12t + 6s < 960$

3) Let the number of Php 100-peso tickets be 'p' and let the number of Php  50-peso tickets be 'q'.

According to the question ,

Difference of p & q is not less than 30

Hence the linear inequality is ⇒$p - q > 30$
