It is when every value in the solution set with satisfy the inequality and no other value will. Example solve 2x+3 is less than or equal to 7.
Answer:
The correct answer is - 625.36.
Step-by-step explanation:
Given:
Fixed mothly plan - 616
free minutes - 150
Used minutes - 170
Free text - 150
Used text - 182
Charging amount over free limit - 18p
Solution:
Number of minutes over the limit - 170 - 150 = 20
Number of text over the limit - 182 - 150 = 32
So the extra amount that will be add to the monthly charge would be -
(20*0.18) +(32*0.18)
and the total charge of the month would be -
= 616+(20*0.18) +(32*0.18)
= 616+3.60+5.76
= 625.36
Thus, the correct answer would be - 625.36
(1,35)(2,60)(3,92)(4,120)(5,175)
Answer:
3/12 is less than 3/4
Step-by-step explanation:
3/12 is the same as 1/4, which is 0.25
3/4 is 0.75
