Question 162222: Our teacher didn't explain much about using Cramer rule with fractions so im at a lost at this equation.
{(2/3)x + (1/5)y = 3
{(3/2)x + (5/3)y = (2/3)
If it makes it any easier, our teacher said we can also use subtitution and elimination method. : Our teacher didn't explain much about using Cramer rule with fractions so im at a lost at this equation.

Question 161857: Calculate the area of the triangle with the following vertices:
(-3, -3), (0, -3), (1, 1)
4 sq units
12 sq units
6 sq units
15 sq units
9 sq units
2 sq units
This is multiply choice, and the possible answers are above as you can see. I have tried everything I can think of to come across the correct answer, but im so confused. I would really apperciate someone explaining how to get the correct answer and what the answer is. Thank you so much!: Calculate the area of the triangle with the following vertices:

Question 160610: [ 8 10 -17]
[-5 -2 11]
[16 9 15]
[-4 20 4]
[-5 5 -15]
[-17 -7 -1]
I need to find the product of the two matrices. I know they look a little funny,im not sure how to get them set up right. The first one is a (3X3) and the second a (3x3), so i know it is defined, and the product is able to be found. I can do addiction,but im completly confused by multiplication. Id love to see the step and the correct answer. I really appericate your help!: [ 8 10 -17]
