24=3/4R.<br> Please reply step by step!
beks73 [17]

Answer:

r = 32

Step-by-step explanation:

R is the variable that we are trying to find.

24 = 3/4r

Since r is being multiplied by 3/4, we need to divide 3/4 on both sides to "undo" the multiplication.

24 / 3/4 = 3/4r / 3/4

32 = r

Therefore, r = 32.

To check, we can plug 32 into the equation.

24 = 3/4 x 32

3/4 x 32 = 24

NikAS [45]

Answer:

A college student took 4 courses last semester. His final grades, along with the credits each class is worth, are as follow: A (3), B (4), C (2), and D (3). The grading system assigns quality points as follows: A: 4; B: 3; C: 2; D: 1; and F: 0. Find the student’s GPA for this semester. Round your answer to the nearest thousandth.

another way is

This is a weighted average question. You are going to "weight" each course by the number of credits it is worth and then divide by the total number of credits. In other words, you are going to multiply each grade (A=4, B=3) by the number of credits attached to that grade. This will ensure that the courses that have more credits count more in the overall average. Then you are going to divide by the total number of credits to get the overall GPA.

So,

(3*4 + 4*3 + 2 *2 + 3*1)/(3+4+2+3) = GPA
