Solve B=1/4m(s+z) for s

ElenaW [278]

Answer:

$s = \frac{-mz+4B}{m}$

Step-by-step explanation:

Step 1: Distribute.

$B = \frac{1}{4}m * s + \frac{1}{4}m * z$
$B = \frac{1}{4}ms + \frac{1}{4}mz$
$\frac{1}{4}ms + \frac{1}{4}mz = B$

Step 2: Subtract 1/4(mz) from both sides.

$\frac{1}{4}ms + \frac{1}{4}mz - \frac{1}{4}mz = B - \frac{1}{4}mz$
$\frac{1}{4}ms = -\frac{1}{4}mz + B$

Step 3: Divide both sides by m/4.

$\frac{1}{4}ms/\frac{m}{4}=(\frac{-1}{4}mz + B)/\frac{m}{4}$
$s = \frac{-mz+4B}{m}$

11 less than 3 times a number is the same as 75 less than the product of minus 1 and the number what is the value of the number

DaniilM [7]

Answer:

(-16)

Step-by-step explanation:

Let the number = x

11 less than 3 times a number: 3x -11

75 less than the product of minus 1 and the number: (-1)*x - 75 = -x -75

3x - 11 = -x -75

3x -11 +x = -75

4x - 11 = -75

4x = -75 +11

4x = -64

x = -64/4

x = -16
