It is not possible to answer this question because people find different things easy or difficult. What you find easy I might find difficult, and conversely.

30 ml is equal to 30 ml. You have not given us any other unit to convert, so that's the answer.

f(x) = 1/3x3

f'(x) = ∫ 1/3x3 dx

f'(x) = 1/3∫ x3 dx

f'(x) = 1/3 * 3 * x2

f'(x) = x2

When finding an antiderivative, substitution can be very helpful. In your integral expression, look for a term that, if you took the derivative and perhaps manipulated it a bit, would give you another term in the same equation. For example, if your integral is ∫tanxdx or ∫((sinx)/(cosx))dx , you can choose cosx as your arbitrary variable (often u or w). If u=cosx, du=-sinxdx. Therefore, your expression using u becomes -∫du/u. We know that the antiderivative of 1/u is ln (absolute value x) +C. So, our answer with u is -ln (abs. val. u) +C. But BE CAREFUL, this is not your final answer. You must plug in the value you originally designated as u. Therefore, the final answer is -ln (abs. val. cosx) +C, with C as an arbitrary constant.

12 x 5 = 60

That's because 12 x 100 = 600

12/2 = 6

No, it has an infinite number of solutions. The coordinates of each and every point on the line 3x + 2y + 4 = 0 is a solution.

It is equal to exactly one million: not more nor less.

Any pair of numbers where the 'y' is 5 more than the 'x'. There are an infinite number of suitable pairs.

2y-2x=10

2y-2x+2x=10+2x

2y=2x+10

divide both side by 2.

y=x+5

x2 - 3x - 4 = 0 so (x+1)(x-4) = 0, so x+1 = 0 and x-4 = 0, so x = -1 or 4

365 divided 2 is:

365/2 = 182.5

If by fraction, then 182 1/2.

By words: one hundred two and one half.

2x + 4 = 10

2x = 10 - 4 = 6

2x = 6

x = 6/2 = 3

6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1

(3x+1)(2x+4) = 6x2+4+2x+12x = 6x2+14x+4

If it's tan(x3), the the thingy is 3x2/(cos2(x3)) i think

Else, if it's tan(3x), then it's 3/(cos2x)

If you need more help with this, search "chain rule" and "derivative" on wikipedia.

x + 3y = 2

2x - 3y = 22

Add the two equations: 3x = 24

Divide both sides by 3 to give x= 8.

Substitue this value of x in the first equation to give 8 + 3y = 2

Subtract 8 from both sides: 3y = -6

Divide both sides by 3: y = -2

Solution: (X, y) = (8, -2)

its really easy say you wanted to find the percentage correct if you got 20/30 for an exam you simply divide 20 by 30 and then times the answer by 100 eg 20/30 = 0.6666 0.6666 x 100 = 66.66 so your percentage is 66.66% !!!

X-y=1

As of October 11, 2011, the record for the computerized listing of the numbers of Pi is some 10 Trillion. See the link below for more on the subject.

It might be easier to calculate using numeric values directly if the equation is really simple.
