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:
0.153
Step-by-step explanation:
It has been a long time since I've done this, so I hope it is correct:
cos = adjacent side / hypotenuse
cos x = 13 / 85 = 0.153
Answer:
y=4
Step-by-step explanation:
3(9) +4y= 43
27+4y=43
4y=16
y=4
Answer:
y = (3/4)x - 6
Step-by-step explanation:
if line is parallel to -3x + 4y = 4, that means that they both have the same slope
Slope of that second line is 3/4.
now time to find the y-intercept
0 = 3/4*8 + b
therefore, b = -(3/4)*8 = -3*2 = -6
Therefore, equation of line is y = (3/4)x - 6
Substitute the values given.
-2-3(2) then solve
Your answer should be -8
