X=weight of the jug
y=witht of liquid when the jug is full
we suggest this system of equations:
x+y/5=250
x+4y/5=550
we solve this system of equations by equalization method.
x=250-y/5
x=550-4y/5
250-y/5=550-4y/5
least common multiple=5
1250-y=2750-4y
-y+4y=2750-1250
3y=1500
y=1500/3
y=500
x=250-y/5
x=250-500/5
x=250-100
x=150
Answer: weight of the jug = 150grams.
Answer:
C
Step-by-step explanation:
The expression is x>55 and 55 isn't included
6 1/3=19/3
8.25=8 1/4=33/4
in multiplying fraction, all you have to do is
multiply the numerators 19x33=627
same with the denominators 3x4=12
627/12 reduce if possible
209/4
Volume of cylinders = pi x r^2 x height Simplifying the ratio: 1.6/3 = 16 / 30 (multiply and divide by 10 to remove the decimal) Volume Ratio = 512:27
