X pounds of $3
y pounds of $3.25
x+y = 200
300x + 325y = 320*200
300x + 325y = 64000
x+y =200
300x +325y =64000
Solve by eliminating
Multiply top one w/-300
-300y =60000
325y=64000
25y = 4000
y= 160 then
x + 160= 200
x = 40
So the mixture has;
40 pounds of $3 coffee
160 pounds of $3.25 coffee
Answer:
2>y
Step-by-step explanation:
4/9>y/18
Here u cross multiple
4*18 >9*y
72>9y
the you divide both sides by 9
72/9>9y/9
8>y

It's impossible to give exact answer as you've not attached the image. But I think I can help you by giving some rulles about rotation. 180° rotation is (x;y) change to (-x;-y); 90° counterclockwise (x,y) change to (-y, x); then clockwise <span>90° (x,y), cange to (y, -x). Hope it will help.
