Question

Выразите каждую из букв, входящих в формулу через остальные: а) a•b=s b) a•m=f в) f•s=a

Answer 1

А) а × b = s
a = s / b.
b = s / a.

b) a × m = f
a = f / m.
m = f / a.

в) f × s = a
f = a / s.
s = a / f.

Answer 2

а)  a = s/b,  b = s/a

b)  a = f/m,  m = f/a

f) f = a/s, s = a/f

Answer 3

a) a•b = s+b

To express each letter in terms of the others in the equation a•b = s+b, we can rearrange the equation to solve for each variable.

Let's start with a:

a•b = s+b

Subtracting b from both sides:

a•b - b = s

Factoring out b:

b(a - 1) = s

Dividing both sides by (a - 1):

b = s / (a - 1)

So, we have expressed b in terms of a and s.

Next, let's solve for s:

a•b = s+b

Subtracting b from both sides:

a•b - b = s

Factoring out b:

b(a - 1) = s

Adding b to both sides:

b(a - 1) + b = s+b

Simplifying:

b(a - 1 + 1) = s+b

b(a) = s+b

Dividing both sides by b:

a = (s+b) / b

Now, we have expressed a in terms of b and s.

b) a•m = f

To express each letter in terms of the others in the equation a•m = f, we can rearrange the equation to solve for each variable.

Let's start with a:

a•m = f

Dividing both sides by m:

a = f / m

So, we have expressed a in terms of m and f.

Next, let's solve for m:

a•m = f

Dividing both sides by a:

m = f / a

Now, we have expressed m in terms of a and f.

c) f•s = a

To express each letter in terms of the others in the equation f•s = a, we can rearrange the equation to solve for each variable.

Let's start with f:

f•s = a

Dividing both sides by s:

f = a / s

So, we have expressed f in terms of s and a.

Next, let's solve for s:

f•s = a

Dividing both sides by f:

s = a / f

Now, we have expressed s in terms of f and a.

In summary:

- For the equation a•b = s+b: - b = s / (a - 1) - a = (s+b) / b

- For the equation a•m = f: - a = f / m - m = f / a

- For the equation f•s = a: - f = a / s - s = a / f

These expressions allow us to express each letter in terms of the others in the given equations.
