What is 2 1/10 + 1 2/7 + 4 9/10?

8 2/7

Step-by-step explanation:

Turn 2 1/10 into an improper fraction:

21/10 + 1 2/7 + 4 9/10

Turn 1 2/7 into an improper fraction:

21/10 + 9/7 + 4 9/10

Multiply 21/10 and 9/7 and combine the fractions into an improper fraction:

21/10 * 9/7 = 237/70

Turn 4 9/10 into an improper fraction then add:

237/70 + 49/10 = 58/7

Turn 58/7 into a mixed number (final step):

58/7 = 8 2/7

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

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
