I believe it is 72 because there is a right angle so thats 90 the known angle is 18 so thats 18-90-18=72
Answer:
-20x / (x-12) = y
Step-by-step explanation:
3/x - 5/y = 1/4
Multiply each side by 4xy to clear the fractions
4xy ( 3/x - 5/y = 1/4)
Distribute
12y - 20x = xy
Subtract 12y from each side
-20x = xy -12y
Factor out y
-20x = y(x-12)
Divide each side by (x-12)
-20x / (x-12) = y
2*_=16
16/2=8
2*8=16
So.. 9*8=72
Therefore Josie got 72 answers correct
Answer:
4/5 is greater
Step-by-step explanation:
Replace the C and D with 6 and 7.
1/4 (6) + 3 (7)
6/4 + 21
6/4 + 84/4 = 90/4
90/4 = 22.5
Hope this helps!
