2/3y=27<br> how do i figure out what 2/3y=27 is?
saveliy_v [14]

Answer:

y=40.5

Step-by-step explanation:

you need to get y out of a fraction, to do so multiply by the denominator on both sides

3(2/3y) = 3(27)

then divide to solve for y

2y = 81

y=40.5

a class with 30 students had an average score of 80 on a test. A class with 20 students had an average score of 90 on the same t
snow_tiger [21]

The average score of all the students in both classes is 84.

<h3>How to calculate the average?</h3>

The class with 30 students had an average score of 80 on a test. The total score will be:

= 30 × 80

= 2400

A class with 20 students had an average score of 90 on the same test. The total score will be:

= 20 × 90

= 1800

Total scores = 2400 + 1800 = 4200

Number of students = 20 + 30 = 50

The average score will be:

= Total score / Total students

= 4200 / 50

= 84
