2 : x
17 : 102
Cross multiply.
17x = 204
Solve for x; how many batches for 102 people.
17x=204
X = 12
She needs to make 12 batches
y/5 = x
multiply by 5 on each sides
y = 5x
There you go! I really hope this helped, if there's anything just let me know! :)
Find slope
slope betwen 2 points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so
first make denoms same
denom is 10
(4/5,1/5) turns to (8/10,2/10)
(1/2,3/2) turns to (5/10,15/10)
slope=(15/10-2/10)/(5/10-8/10)=(13/10)/(-3/10)=13/-3=-13/3
use point slope
use (4/5,1/5)
y-y1=m(x-x1)
a point is (x1,y1) and slope is m
y-1/5=-13/3(x-4/5)
expand
wait, we don't need to do that, the only one with slope -13/3 is D
answer is D
Answer:
X=5 Y=-4
Step-by-step explanation:
Adding or subtracting to make the original number the closest 10, 100, etc.
