The second equation is not complete and there is not sufficient information for a solution. It would make no sense for me to guess what a + b equals since, in that case, I may as well start posting my own questions and answering them!
70000000y=35t
N = 3. That really is all there is to it.
y = 5
Now originially, there would not be a solution for this answer.. but! If you were to use a decimal to find your answer and round it to the nearest tenths, then there would be many solutionsEX:51.25 x 2 = 102.5102.5 rounded to the nearest tenths would be 103
You have two unknown variables, x and y. You therefore need at least two independent equations to find a solution.
There is one solution. To find it, divide both sides of the equation by 2. This leaves you with x=5, where 5 is your solution.
(Since 5 times 20 does equal 100, the solution is correct.
x-3x = -8 -2x = -8 x = 4
Just try cubing some small numbers. You should find the solution quickly.
The pOH is 6,4.
The idea is to find a number which, when square, equals the given number. For example, asking for the square root of 100 means solving the equation x2 = 100. The solution, in this case, is 10. (Minus 10 is also a solution, but the term "square root" refers to the positive solution in this case.)The idea is to find a number which, when square, equals the given number.
