50% of what number of salads is 10   This can be  rewritten as;   50% of x = 10   50/100 * x = 10   1/2 * x = 10   x/2 = 10   cross multiply;   x = 10 * 2   x = 20

Solving for X (answer)

Well if you're using the same kind of keyboard format as my laptop where the equals to (=) and addition (+) signs are toggled by the same key, the equation would then have to be;   (x-5)/(-2) = (x+1)/(-3)   we'd cross multiply   (x-5)(-3) = (x+1)(-2)   (-3x...

What percent of 20 is 5?   This can be rewritten as;   X% of 20 = 5   which would be;   x / 100 * 20 = 5   20x / 100 = 5   cross multiplying   20x = 100 * 5   20x = 500   x = 500...

If this is what you mean;   A + B + C = AB   C = AB - A - B   But if it is as is;   A + B + C + AB   A + B + C + AB = 0   A + B + C = - AB   C = - AB - A - B   which...

-6-2(3x-18)=18 (answer)

- 6 - 2(3x - 18) = 18   Using BODMAS   B - Bracket O - Order of D - Division M - Multiplication A - Addition S - Subtraction   we'll have to solve the brackets first.   - 6 - 2(3x - 18) = 18   - 6 - 6x + 36...

-5n + 6 = 5n - 4   Bring like terms together;   -5n - 5n = -4 - 6   -10n = -10   divide both sides by -10 to find n   -10n / -10 = -10 / -10   n = 1

So you are given; √[(x2+y2)=4]   we'll break them down to various individual components;   √x2 + √y2 = √4   the squares cancel out the square roots and you find the square root of 4   x + y = 2       So...
