RJ trips over his shoe laces every 15 steps. Matthew says "gottem" every 6 seconds. If the boys both start walking down the hall at the same time,
how many seconds will pass before RJ trips & Matthew says "gottem" at
the same time? *

69 seconds, or 1 minute and 9 seconds

Step-by-step explanation:

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
