Juan has taken four skill checks for the third grading period and earned a 60, a 75, an 85 and a 95. If the Unit Test counts as TWO skill check grades, what is the range of scores that Juan can earn on the Unit Exam so that he will earn a B? (Between 79 and 90) Write the inequality that can be used to solve for the range of values Juan must earn on his unit exam to meet his goal?

Please note that I am using the < and > symbol, because he wants to earn a B which is BETWEEN 79 and 90 and does NOT include them.

I also completed the first step of multiplying all parts of the inequality by the denominator (6) to "elliminate" it from my average formula.

savings account is an account only used for saving money. this acts as an emergency source of funding for an individual. answer a would result in the money in his account to grow as it specifically states that interest is compounded daily at the rate of 2%

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

whaere is the picture
