Melinda will take 15 quizzes this semester. she would like to score a b or better on at least 90% of them. so far, she has gotten a b or better on 6 quizzes. which inequality can be used to determine how many more quizzes she must score a b or better on.

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

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
