Solve the equation for k.

Question

k/−2 = −10

Answer 1

To solve the equation \( \frac{k}{-2} = -10 \), we can start by isolating \( k \).

1. Multiply both sides of the equation by \(-2\):

\[ k = -10 \times -2 \]

2. Calculate the right side:

\[ k = 20 \]

So, the solution is:

\[ \boxed{20} \]

Answer 2

Solve the equation for y.

5y−10=−25

Answer 3

To solve the equation \(5y - 10 = -25\), follow these steps:

1. Add 10 to both sides to isolate the term with \(y\):

   \[ 5y - 10 + 10 = -25 + 10 \]

   This simplifies to:

   \[ 5y = -15 \]

2. Divide both sides by 5 to solve for \(y\):

   \[ y = \frac{-15}{5} \]

   This simplifies to:

   \[ y = -3 \]

Thus, the solution is:

\[ \boxed{-3} \]

Answer 4

Solve the equation for x.

−3x+4=−8

Answer 5

To solve the equation \(-3x + 4 = -8\), follow these steps:

1. Subtract 4 from both sides to isolate the term with \(x\):

   \[ -3x + 4 - 4 = -8 - 4 \]

   This simplifies to:

   \[ -3x = -12 \]

2. Divide both sides by -3 to solve for \(x\):

   \[ x = \frac{-12}{-3} \]

   This simplifies to:

   \[ x = 4 \]

Thus, the solution is:

\[ \boxed{4} \]

Answer 6

Solve the equation for w.

−0.1w+23.2=−0.8

Answer 7

To solve the equation \(-0.1w + 23.2 = -0.8\), follow these steps:

1. Subtract \(23.2\) from both sides to isolate the term with \(w\):

   \[ -0.1w + 23.2 - 23.2 = -0.8 - 23.2 \]

   This simplifies to:

   \[ -0.1w = -24 \]

2. Divide both sides by \(-0.1\) to solve for \(w\):

   \[ w = \frac{-24}{-0.1} \]

   This simplifies to:

   \[ w = 240 \]

Thus, the solution is:

\[ \boxed{240} \]

Answer 8

Solve the equation for x.

4−2x=10

Answer 9

To solve the equation \(4 - 2x = 10\), follow these steps:

1. Subtract 4 from both sides to isolate the term with \(x\):

   \[ 4 - 2x - 4 = 10 - 4 \]

   This simplifies to:

   \[ -2x = 6 \]

2. Divide both sides by -2 to solve for \(x\):

   \[ x = \frac{6}{-2} \]

   This simplifies to:

   \[ x = -3 \]

Thus, the solution is:

\[ \boxed{-3} \]

Answer 10

Solve the equation for y.

−1/5y+3=−7

Answer 11

To solve the equation \(-\frac{1}{5}y + 3 = -7\), follow these steps:

1. Subtract 3 from both sides to isolate the term with \(y\):

   \[ -\frac{1}{5}y + 3 - 3 = -7 - 3 \]

   This simplifies to:

   \[ -\frac{1}{5}y = -10 \]

2. Multiply both sides by -5 to solve for \(y\):

   \[ y = -10 \times -5 \]

   This simplifies to:

   \[ y = 50 \]

Thus, the solution is:

\[ \boxed{50} \]
