40
n = (65 - 25)/8 ie 5
360 - 80 - 65 - 35 - 25 =280 - 65 - 35 - 25 =215 - 35 - 25 =180 - 25 =155
70
No, it is -5/13
X=65
Well, isn't that a happy little math problem we have here! To find the original number, we can simply divide 65 by 1.25 (which represents the 25% increase as a decimal). So, 65 divided by 1.25 equals 52. So, the original number was 52.
Well, honey, if you want to solve for C in that little equation, you just need to multiply 10 by 4 to get 40, then add 25 to it. So, C equals 65. Math can be a piece of cake when you break it down like that!
No, 65 degrees and 25 degrees are not complementary angles. Complementary angles are defined as two angles whose measures add up to 90 degrees. In this case, 65 + 25 equals 90 degrees, so they are indeed complementary angles.
R = 65*e-5k = 65/(0.006738)k
To solve the equation (25 + 8x = 65), first subtract 25 from both sides to isolate the term with (x): (8x = 65 - 25), which simplifies to (8x = 40). Next, divide both sides by 8 to solve for (x): (x = \frac{40}{8}). This gives you (x = 5).
65/65=1+65=66
If you have 25 + __ = 90, the first step is to rearrange this problem into something you can answer. This would make the new problem 90 - 25 = ____. Once you solve this (It equals 65 by the way) you can then do 25 + 65 = 90. This makes it a true statement. 5 (from 25) + 5 (from 65) = 10 and 20 + 60 = 80, and finally 80 + 10 = 90.
