In a primary school the ratio of boys to girls is 6:7 For each statement write down whether it is:
D Definitely true
C Could be true
F False
(i) The number of boys in the school is 48
(ii) The fraction of boys in the school is Ą
(iii) The fraction of girls in the school is 13

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
