The sum of two numbers is 27. The larger number is 6 more than twice the smaller number. Which system of equations can be used to find the two numbers

a. xy=27
y=6+x

b. x+y=27
y=6=2x

c. xy=27
y = 6+2x

d. x=y=27
y=6=x

Step-by-step explanation:

x + y =27

x is the smaller number

y = 2x + 6

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
