This one's a little bit harder but i'm sure i can solve it. I usually pick the smaller number to solve first and then substitute the larger one. -2x+y=-16 -8x-7y=-20
So you'll solve
-2x+y=-16 +2x/ +2x y=2x-16------- this is what y means so you substitute y in the other equation for this answer.
-8x-7y=-20 -8x-7(2x-16)=-16------------------------Use distributive property to simplify. -8x-14x+112=-16 -22x+112=-16 -112 -112 -22x=-128---------------Divide -22 on both sides x=5.82
(a) Question: There are 8 horses in a race at Retama Park. You could win a BIG jackpot if you can pick the finishing order for ALL 8 of the horses. Find the number of possible orders in which the hors v
According to the picture, angles 1 and 2 have the same measure because they are corresponding angles. Make equal both expressions for 1 and 2 and find x.
x is 3/2. Replace this value in both expression to find the measure of each angle.
