For this case we have the following solution.
 x = gallons of water to be added
 For the 10% solution we have:
 0.1 * 8 = 0.8
 Then, for 5% we have:
 (0.8 / x + 8) = 0.05
 Rewriting:
 (0.8 / x + 8) = (5/100)
 Answer:
 An equation can be used to find x, the humber of gallons of water he should add is:
 (0.8 / x + 8) = (5/100)

Use estimation to help you choose the correct answer.<br><br> 0.945 x 7.6 =
hoa [83]

Remark

The thing you must not do is write 7.182 as your answer. That is the exact answer found using a calculator.


What to do.

What you should do is multiply two rounded numbers together.

7.6 rounded is 8 roughly


0.945 is almost 1.


Your answer is 8*1 = 8 roughly. This skill is very handy when you are writing a test and you want to see if you've done the question correctly. It is easy to misplace a decimal or put in incorrect digits and this is a quick check on things like that.
