(2) How many 3-meter pieces of rope can be cut from a rope 20 meters long, and how many meters will remain?
(Show your work.)

(Ans.). pieces, meter(s) remain(s)

6 pieces, 2 meter left

Step-by-step explanation:

20/3=6 pieces and 2 meter left

the fraction is 6 2/3

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has 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
