C = 3b
Step-by-step explanation:
If each bottle costs 3 dollars, then the cost of b bottles would be 3b.
Answer:x=90° y=58° z=32°
Step-by-step explanation:
x=90
y=180-(90+32) sum of angles in a triangle is 180
y=58
y+90+z=180 they are supplementary
58+90+z=180
148+z=180
z=180-148
z=32
Answer:
y=(8/9)x + 4 and 2/3
Step-by-step explanation:
the slope of this line:
change in y/change in x
change in y=6-(-2)=8
change in x=-6-3=-9
change in y/change in x= 8/9
8/9 is the slope, so you plug it in for m in the standard form equation. You then use one point's x and y values to substitute for x and y in the equation, and solve for b, which is the y intercept
y=mx+b
y=(8/9)x+b
-2=(8/9)*3+b
-2=8/3+b
-4 and 2/3=b
Answer: (30m-9n)/270
First we start with m/9-n/30.
We multiply the denominators to get 270.
Then we multiply the numerators by the original denominators to get (30m-9n).
To check, we can use m=2, and n=4
2/9-4/30=4/45
(30*2-9*4)/270=24/270=4/45
