Nancy and Margie are both reading the same book for school. Nancy has read 84 pages of the book and plans to read 12 pages a day until she finishes it. Margie has read 92 pages of the book and plans to read 8 pages a day until she
finishes it. Which of the following could be used to find how many more days Nancy must read before she has read
more pages of the book than Margie?
O 84 + 12x = 92 + 82
O 84 + 12x > 92 + 8x
O 92 +82 > 84 + 12
O 120 + 80 > 92 - 84

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

the answer is 40.

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
