A cyclist took 3 h to cycle from Town X to Town Y. His average speed was 12 km/h. If his average speed was increased by 3 km/h, he would then take hours minutes for the journey.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

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
