Addition property of equality
x+10>13 it wouldn't be x+10-13 ??
(9/13) / (10/13) =(9/13) x (13/10) =9/10
x + 13
15 x 13 = 195A simpler way of breaking this down is:15 x 13 =(10 + 5) x (10 + 3) =(10 x 10) + (10 x 3) + (10 x 5) + (5 x 3) =100 + 30 + 50 + 15 = 195
x - 10
13 > -10 + x/4 if 23 > x/4 if 92 > x that is, when x < 92
x+10>13 it wouldn't be x+10-13 ??
Just do 3+What ever number here So say 3+10=13 Than you do 13+10=23 Boom there. ============================= Another approach . . . It could be (x + 3) + 10 or it could be (x + 10) + 3 . Either way, it becomes (x + 13) .
so half of x is 10 + 3 ie 13 making x = 26
13 - 10% = 13 x (1 - (10/100)) = 13 x 0.9 = 11.7
If: -3-x = 10 Then: x = -13
x + (13-10)
10 % of 13 = 1.3 20% = 1.3 x 2 20 % = 2.6 answer = 13 + 2.6 = 15.6
(9/13) / (10/13) =(9/13) x (13/10) =9/10
If: -3-x = 10 Then: x = -13
x + 3 + 10 = x + 13
The wavelength of radiation with a frequency of 1.5 x 10^13 Hz can be calculated using the formula λ = c / f, where c is the speed of light (~3.00 x 10^8 m/s). Substituting the values gives λ = 3.00 x 10^8 / 1.5 x 10^13 = 2 x 10^-5 meters. This radiation has a shorter wavelength than red light, which has wavelengths ranging from about 620-750 nm.
