4/5n – 1/5 = 2/5n
Add 1/5 to both sides
4/5n = 2/5n + 1/5
Subtract 2/5n from both sides
2/5n = 1/5
Divide both sides by 2/5
n = 1/2
Answer:
200% increase.
Step-by-step explanation:
The original value was tripled.
Answer:
Option D. The circumference
Step-by-step explanation:
A). Area 'y' of square with side 'x' will be represented by
y = (Side)²
y = x²
Since the degree of this polynomial function is 2, It's a quadratic equation.
B). Area of the circle = πr²
y = π(x)²
Since the degree of this polynomial function is 2, It's a quadratic equation.
C). Volume of a cube = (Side)³
y = x³
Since the degree of this polynomial function is 3, It's not a linear function.
D). Circumference of the circle = 2πr
y = 2π(x)
Since the degree of this polynomial function is 1, it's a linear function.
The answer is B. Once you combine the two amounts consumed (which you’d put them in like terms and reduce) you’d subtract the sum from 3
There for
1 1/4 = 1 2/8
1 2/8+7/8 = 1 9/8
1 9/8 = 2 1/8
2 1/8 is the sum of the amount consumed there for,
3- 2 1/8 = 7/8
If you solved with A you would essentially be adding a initial quart of 3 and 1 1 1/4 which assumes you added milk then drank 7/8 of a quart, C assumes you don’t consume any and you have 1 1/4 and 7/8 quarts of milk above the 3 quarts and D would leave you with 1.125 or 1 1/8 there for it is also incorrect.
Pretty sure its 18cm. Not exactly sure.
