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

Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .<span>X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 30/5 = 6.Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 30/-3 = -10.Slope is -5/-3 = 1.66666666666667.<span> Equation in slope-intercept form: y=1.66666666666667*x+-10.</span></span>
I think you can solve it by doing this:
10(10,000+0.06)= Final Balance
6 months + 6 months = 1 year
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
She has to pay twice a year
Now that we know that just multiply 2 by 5 and you get 10. 10(10,000+0.06)= Final Balance
So it should be 100000.6
Not sure if that's right so ask someone to check
She could have taken the price and number of pounds and divided the price by two until she had the price for one of oranges. that is all i know, i hope it helps.
