Q: What is 135 equals 3s plus 15?

Write your answer...

math

2h2s + so2 ----------> 3s + 2h2o

decomposition

s = 15

2s + s + 12 =132 ie 3s = 132 -12 3s = 120 s = 40

2Al+3S--->Al2S3

2s + s + 12 = 132 3s + 12 = 132 3s = 132 - 12 3s = 120 s = 40

3s + 4t + 2s + 5s + 6tGroup all of the like 's' terms & 't' terms together:(3s+2s+5s) + (4t + 6t)10s + 10t or 10(s+t)

3s + 1

Through a process of elimination and substitution the solutions are s = 8 and x = 5

2h2s + so2 - 2h20 + 3s

r + s = 4 and 2r + 3s = 8 multiply the first equation by 2 giving 2r + 2s = 8 subtract this from the second equation giving s = 0 So r = 4 and s = 0.

15

No.

s = 4

3 + .3 + .33

2t-4s

Simplified its 12r+3s

12r - 15s - r + 3s = 11r -12s

You have to combine equal terms. -5r-9s+9r+3s-6 = -5r+9r-9s+3s-6 = 4r-6s-6

5 + 2s + s = 3s - s + 8 Combining like terms on the same side: 5 + 3s = 2s + 8 Subtracting 2s from both sides: 5 + s = 8 Subtracting 5 from both sides: s = 3

7-2s+4+5s ..... Okay first you combine like terms(add the like terms)..so its going to be 11+3s I did 7+4=11 then -2s+5s=3s So the answer can be 11+3s or 3s+11

-7 = 3s - 1 +1 +1 (add 1 to both sides to get the variable alone) ___ ____ -6 = 3s __ ___ (-6 and 3s both divided by 3) 3 3 -2 = s

3.5111

The answer is 45 135=3x3x3x5 315=3x3x5x7 each number has at least 2 3s and one 5 3x3x5=45 Your welcome
