is it zero???!?!!!!!!!!!!!
9y - 5x = 20
or, (9y - 5x) / 20 = 1
or, 9/20 y - 1/4 x = 1
compare with x/a + y/b = 1
you'll get
x intercept (a) = -4
y intercept (b) = 20/9

ratio of 9:2
means for every 9 cows there are 2 horses
72/9 = 8
8 x 2 = 16
there are 16 horses
Answer: 16%
Step-by-step explanation:
The total number of species of shark evaluated = 465
Number of sharks currently endangered or threatened = 74
Percent of sharks endangered = (Number of sharks / Total number of sharks evaluated) x 100%
= (74/465) x 100%
= 0.1591 x 100%
= 15.91%
Round 15.91% to the nearest whole percent = 16%
Thus, 16% of the total sharks evaluated are currently endangered or threatened.
