Use elimination to solve this system of equations. 2r + 3s= 9 and 3r + 2s= 12
timama [110]
<span>2r + 3s= 9 <=> -6r -9s = -27;</span>
<span>3r + 2s= 12 <=> 6r + 4s = 24;
                    => 0*r -5*s = -3 => s = 3/5;

2*r + 3*(3/5) = 9<=> 10*r + 9 = 45 <=> 10*r = 36 => r = 18/5;

3/5 + blank over 3 equals 14/15. whats the missing number
vlabodo [156]

Answer:

x = 1/3

Step-by-step explanation:

3/5 + x = 14/15

we need to get a common denominator 15

3/5 * 3/3 = 9/15

9/15 + x = 14/15

subtract 9/15 from each side

9/15 - 9/15 + x = 14/15 - 9/15

x = 5/15

this simplifies  divide the top and bottom by 5

x = 1/3

In your own definition or what it means to you what does it mean to Make A+ your own personal standard
liberstina [14]

Step-by-step explanation:

Grades

1. Letter Grades

A+, A, A- indicates excellent performance.

B+, B, B- indicates good performance.

C+, C, C- indicates satisfactory performance.

D+, D, D- indicates less than satisfactory performance.

F indicates unsatisfactory performance (no credit: always include last date of attendance).

P indicates Pass (A-, B and C will automatically be replaced by "P" when the Pass/No Pass option has been requested. A+ and A will be recorded as "A+" and "A", not "P").

NP indicates No Pass (D+, D, D-, and F will automatically be replaced by "NP" when the Pass/No Pass option has been requested).

NC (No Credit)Note: The NC grade was eliminated as of Winter 2019.

U indicates Audit (class taken for personal enrichment).

“ I” indicates Incomplete: An Incomplete can be provided when a student has satisfactorily completed 75 percent or more of the course work as defined by the instructor, but is unable to finish the remaining required to be scheduled work due to circumstances beyond the student’s control. An Incomplete grade is not used to avoid a failing grade or to address student convenience.

In general, a grade of Incomplete is to be made up within one term from the last day of the original term the course was taken, but, may be extended up to one year at the discretion of the instructor. Assigning an Incomplete requirements mutual agreement between the student and instructor, outlined in a contract (or written agreement) that contains the following: a description of the work to be completed, a deadline for its completion, and a standard grade that will be earned if the deadline is not met. The student is responsible for understanding the terms of the contract. The student cannot be required to register again for the Incomplete course (graded or audit) during the term of the Incomplete. At the end of the contract date, the Incomplete will convert to a standard grade as determined by the terms of the contract.;

2. Grade Points

Grades and grade points that are included in the computation of the Grade Point Average (GPA) are assigned as follows:

A+ = 4.30

A = 4.00

A- = 3.70

B+ = 3.30

B = 3.00

B- = 2.70

C+ = 2.30

C = 2.00

C- = 1.70

D+ = 1.30

D = 1.00

D- = 0.70

F = 0.00

P, NP, NC, I and U are not used to compute GPA - Note: The NC grade was eliminated as of Winter 2019.

It will always be possible for a student to earn a 4.30 GPA for the term. Pass/No-Pass, Incomplete, No Credit and Audit have no effect on the student's earned credit or GPA credit.

To compute GPA, first find the total grade points for each class by multiplying the points for the grade times the credits for the class. Then add up all the credits and all the points. The GPA is then computed by dividing the total points by the total credits (and rounding up to the nearest one-hundredth).
