Simplify each expression
-3m + 16 - (-13m)
15y - 20y + 15

10m + 16

-5y + 15

Step-by-step explanation:

-3m + 16 - (-13m) =

= -3m + 16 + 13m

= 10m + 16

15y - 20y + 15 =

= -5y + 15

72 fudge and 75 toffee

step-by-step explanation:

i hope this : )

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
