There are: 100/15 = 6 with a remainder of 10
550 divided by 15 equals 36 with a remainder of 10.
3(3r-5s = -16) 5(5r+3s = 64) Multiply all terms in the first equation by 3 and in the second equation by 5: 9r-15s = -48 25r+15s = 320 Add the equations together in order to eliminate s: 34r = 272 Divide both sides by 34 to find the value of r: r = 8 Substitute the value of r into the original equations to find the value of s: Therefore: r = 8 and s = 8
A regular pentagon has a perimeter of 5s. We set this equal to 15, and solve for s, and convert to yards.5s = 15s = 33 feet converted to yards is 3/3 = 1 yard.
15s-15 = 0
It is: 5s(5s-3)
The coordinates 15S, 75W represent a location in Peru, in or near Poroma on the Panamericana Sur.
Because 12/15 divided by 3/3 = 4/5.
12r - 15s - r + 3s = 11r -12s
15s=58.5 s=58.5/15 s =3.9
The coordinates 15S 15E correspond to Botswana, a country located in southern Africa.
