52•(-5)=52•5=260 since a positive number times a negative number equals a negative, the answere is -260
n X .15 = 9 9 / .15 = n 9 / .15 = 60
15 - 12 = 3 B = 15
3a + 15 = 4a Subtract 3a from both sides 15 = a So a is 15.
Simple! 15, as a decimal is 15: that's it. No change!
-15
15 to the 2nd power or 15 squared equals 15 * 15 which equals 225.
Yes. Good work!
Good work ! Did you have a question you wanted to ask ?
The equation is 2a-15=-1 It is possible to work out what a is (as I am going to show below), but as there is no y in this equation, you cannot work out what y is. We have to firstly try and get rid of the -15, so we add 15 to each side, leaving us with 2a=14. To get a on its own, we divide each side by 2, leaving us with a=14.
15 percent 0 equals 0; 0 percent 15 equals 0. Both the above are true
1
9 out of 15 equals 60%
