seventeen over fifteen because the common denominator of 5 and 3 is 15 think about it like this: 4/5x3, 4x3=12, 5x3=15 1/3x5, 1x5=5, 3x5=15 so you get 12/15+5/15 see how they simplify back? then add the numerators and keep the denominator and you get 17/15 or 1 and 2/15
n(n+2)
r = 3 s = 5 t = 6 rs = 3x5 = 15 rt = 3x6 = 18 st = 5x6 = 30
True
Same mathematical signs equal plus Different mathematical signs equal minus Plus Plus = Plus (+)(+) = + Minus Minus = Plus (-)(-) = + Plus Minus = Minus (+)(-) = - Minus Plus = Minus (-)(+) = - So the direct answer to your question would be: plus minus equals minus
(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156
2+3*5 = 2 + 15 = 17
3x5+4=19
3x5 + 4x8 does not have a solution because it is not an equation. Are you looking for it's derivative? That would be: 15x4 + 32x7 Did you want it's indefinite integral? ∫(3x5 + 4x8) dx = x6/2 + 4x9/9 + C Or did you actually mean "three times five plus four times eight"? If so, the answer is 47.
(p+3)5 or p(3x5) depending on what way you say it.
Multiplication is done before addition, so it will be done before the plus. The result is:35 + 3 x 5 = 50
3a + a = 4a Example: a = 5 (3x5) + 5 = 15 + 5 = 20 = 4 x 5
17 = (3x5) + 2 = 5 + 5 + 5 + 2 = 10 + 7
1080 = 2^3x3^3x5 200= 2^3x5^2 LCM (1080,200) = 2^3x3^3x5^2 = 1800
prime factorization of each: 2x3 , 3x5, 2x2x5 so LCM = 2x2x3x5 = 60
This doesn't make any math sense:2⁴ - 1 + 21 = 14 = 7 +3 x 5
There are 15 cells in a 3x5 table, calculated by multiplying the number of rows (3) by the number of columns (5).
