The solution for the equation a(b - c) = d is:

$c = b - \frac{d}{a}$

None of the options is correct

The given equation is:

a(b - c) = d

Expand the left hand side of the equation using distributive rule

ab - ac = d

Subtract ab from both sides

ab - ab - ac = d - ab

-ac = d - ab

Multiply both sides by -1

-1(-ac) = -1(d - ab)

ac = ab - d

Divide both sides by a

$c = \frac{ab}{a} - \frac{d}{a} \\c = b - \frac{d}{a}$

If p varies directly with q, and p = 10 when q = 2, what is the value of p when q = 20?. . Is the answer 40?

meriva

NO, THE ANSWER IS NOT 40.

The solution to the problem is as follows:

If they vary directly, their ratio is always equal to the same number.
Since 10/2 = 5, any p/q has to = 5.
So p/20 = 5

p = 5 x 20 = 100

What is the coefficient of x in the expression x-2

stepladder [879]

Answer:In expression x-2 coefficient of x is equal to one.

Let a be "a" x's coefficient.

If we put "a" to Your equation, it should be looks like:

ax-2

We know that there is only one x, so expression ax have to be equal x

Now we get

From this equation we know that coefficient x "a" is equal to 1.
