If l parallel to m find y

y = 144

because l//m

=> y + x = 180°

but y = 4x (2 vertical angles) => x = y/4

with x = y/4

=> y + y/4 = 180°

⇔ 5y/4 = 180°

⇔ 5y = 180.4 = 720

⇔ y = 720/5 = 144

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
