Anestetic [448]

Answer:

11

Step-by-step explanation:

First, write an equation to represent the situation.

34 = 2a + 12

This equation works because your combined age is half of 68, so 34. If your age is a, then yours sister's age is a + 12. if you add your age to your sister's, you get 2a + 12.

Now just solve for a.

34 = 2a + 12

First, subtract 12 from both sides.

22 = 2a

Then divide both sides by 2.

11 = a

So you are 11 years old. If you need to check your work, your age (11) plus your sister's age (11 + 12, which is 23) is 34, which is half of your grandfather's age.

Flura [38]

Answer:

696\frac{39}{100} meters fence

Step-by-step explanation:

Ben needs to replace two sides of his fence.

The length of one side of fence =  367\frac{9}{100} meters

The length of other side of fence = 329\frac{3}{10} meters

to calculate the length of fence that Ben need to buy we will add the length of both sides.

367\frac{9}{100} + 329\frac{3}{10}

= \frac{36709}{100} + \frac{3293}{10}

= \frac{36709+32930}{100}

= \frac{69639}{100}

= 696\frac{39}{100} meters

Ben need to buy  696\frac{39}{100} meters fence.
