3/4=15
let,
total mass is x
x=4×15/3
=20 kg
so, total mass = 20 kg
=2×20/5
=2×4
=8 kg
Hope this helps!
7 - 8 = -1
the rate of change is -1
Hope this is right,

Answer: 3
Step-by-step explanation: y=-2, also y=-2x+4. Therefore, we got a equation: -2=-2x+4. You then minus 4 from both sides of the equation and you will get -6=-2x. You then solve for x by dividing -6 by -2, you get x=3
Answer:
5 inches out of a foot would be a fraction 5/12.
Step-by-step explanation:
Because a foot is 12 inches, your bottom number of the fraction (the one on the right) would be 12 inches and the 5 inches would go on the top of the fraction (or, on the left; depends on how you write it).
Answer:During 10years ago the number of people living in Sherbury increased by 965 while the number of people living in Yaston increased by 942
Step-by-step explanation:
During the 10 year period,
Let x= increase in the number of
people living in Sherbury
y=number of people living in Sherbury before the increase
Therefore,
5/100 * y = x
0.05y=x
And
x + y = 20265
But y=20x
x + 20x =20265
21x=20265
x=965
During 10years ago the number of people living in Sherbury increased by 965.
Likewise
Let
a=increase in the number of
people living in Yaston
b=number of people living in Yaston before the increase
7.5/100 * b = a
0.075b = a
b=13.33a
a + b = 13502
a + 13.33a=13502
14.33a=13502
a=942
During 10years ago the number of people living in Yaston increased by 942.
Conclusion
During 10years ago the number of people living in Sherbury increased by 965 while the number of people living in Yaston increased by 942.
