Answer:
2. zeros
4. difference
22. 79,158.5
42. 0.0099
50. 4.37
Step-by-step explanation:
2. Only adding 0s after a decimal point does not change the value.
4. Since you are subtracting then you estimate difference.
22. Add each number using place value.

42. 0.01 is really 0.0100. If you subtract 0.0001 then it is like subtracting 100-1 = 99 but in the decimal place. So it becomes 0.0099.
50. Subtract by lining up decimal places. Then move place values to subtract.

Answer:
x = 7
Step-by-step explanation:
1*2*3*4*5*6*7 = 5040
x*8*9*10 = 720x
720x = 5040
720 / 5040 = 7
x = 7.
Because they have a number that divides into them easily
Each "x" on the number line seems to represent a tree that sap has been collected from. That's 15 trees. Furthermore, you know that the total amount of sap is 8 gallons, because it's stated in the question.
To get the amount of sap that would be collected from each tree if it had been distributed equally (also known as the <em>average</em> amount of sap collected from each tree), just do exactly that.
Mathematically, this means you would divide the 8 gallons by 15 trees, or 8 ÷ 15. The total amount of sap collected is equivalent to an average of eight fifteenths of a gallon per tree.
