Radical Equation:

1. Isolate the radical expression.

2. Square both sides of the equation: If x = y then x2 = y2.

3. Once the radical is removed, solve for the unknown.

4. Check all answers.

Another way of saying it:

1. Isolate the radical expression involving the variable. ...

2. Raise both sides of the equation to the index of the radical.

3. If there is still a radical equation, repeat steps 1 and 2; otherwise, solve the resulting equation and check the answer in the original equation.

You walk 2 miles in 1/<br> 2 hour. At that rate, how long will it take you to walk 3 miles?
krek1111 [17]
Hello!

1/2 = 0.5 as a decimal

0.5 ÷ 2 = 0.25

That means you walk 1 mile in 0.25 of an hour. Multiply this by three:

0.25 × 3 = 0.75

Answer:

It will take you 0.75 (or 3/4) hour to walk 3 miles.

Solve for z. 20 − (z + 7) = 0.9
zhannawk [14.2K]

Answer:

x = 12.1

Step-by-step explanation:

20 − (z + 7) = 0.9

Distribute the minus sign

20 -x -7 = .9

Combine like terms

13 -x = .9

Subtract 13 from each side

-x = -12.1

x = 12.1

  • 225 = 25 +  {x}^{2}

  • {x}^{2}  = 225 - 25

  • {x}^{2}  = 200

  • x =  \sqrt[]{200}

  • x = 10 \sqrt{2}

The correct choice is ~ B
