Hey. Don't insult the people trying to help you. Just because you don't take notes, there's no reason for you to lash out. It's communitive because the order doesn't matter if you put it 4*1 or 1*4, it still produces a product of 4

our describes that it's your team not mine ;) ur right :)

y= -2x-13 x= 5.5 -1/2y

It's -5m not 5m

angle 1= x angle 2=8x so 8x+x=180 9x=180 9x= 180 divided by 9 is 20 so x=20 angle 1=20 angle 2=160 Hope it helps :)

You know complementary angles add up to 90 degrees so let x = one angle let 3x = the other angle x + 3x = 90 4x = 90 x = 22.5 degrees so one angle (x) is 22.5 and the other (3x) is (3 x 22.5) = 67.5

x+y=180 y= x+38 x+(x+38)= 180 2x+38=180 -38 =-38 2x = 142 x= 71 plug it in equation 71+71+38= 180 angle 1 = 71 angle 2 = 109

Hi, what are evidence of the 2 superpowers in the cold war.

Thank you Reiny!

I'm a little confused though.. Where did you get the (1/7) and (1/5) in the second line?

Ohh I see. Thank you!

can you plz explain 693 = 9x7x11 so we would need multipliers of 7 and 11 to yield a perfect square so 693x7x11 = 9x49x121 Thanks

im confused, is the answer 1.77827941x10^-10 or 5623413252????

I don't know the answer

These were the present values I had obtained. 1. PV = 1,180,000 2. PV = 671476 3. PV = 1,087,033 4. PV = 1,204,627 4 is the one I had trusted myself least on.
