Not sure what 'open' means but

-42-10=-52
imagine that you are doing this
(-42)+(-10)=-52
neagtive moves backwards
so 
42 units back+10 units back=-52 units back
seems right

true

laila [671]
Splashtown: 25 + 1x
Schlitterbahn: 40
25 + 1x = 40
-25 -25

x = 15

Add. 4.29 + 97.2 + 0.687 =<br> 102.177<br> 140.787<br> 1,407.87<br> 1,021.77
nordsb [41]
4.29 + 97.2 + 0.687 = 102.177

In adding decimal numbers, make sure that the decimal points are aligned. Since each number has different counts of numbers after the decimal point, use 0 to pad the missing places.
    
      4.290
    97.200
   <u>   0.687
</u>  102.177

The count of numbers after the decimal point is the same count of number of the decimal who has the greatest count of number after the decimal point.

4.29 only has 2 counts of places after the decimal point
97.2 only has 1 count of place after the decimal point
0.687 has 3 counts of places after the decimal point. 

The sum of the decimals must also have 3 counts of places after the decimal point.

Write the fraction 1/8 as a percent rounded to the nearest hundredth of a percent where necessary
Irina-Kira [14]
<span>To determine the answer to this you would divide the numerator by the denominator in an equation. The answer to that equation is 0.125. When converting a decimal to a percentage, you shift the decimal point over two places. Thus the percentage is 12.5% and it is unnecessary to round the result to the nearest hundredth of a percent. The answer is 12.5%.</span>
