s = 7, t = -3
3t - 15 = -9 3t - 15 (+15) = -9 (+15) 3t = 6 3t (/3) = 6 (/3) t = 2
It is an equation. Taking it step by step: 17 = 3t - 4 17 + 4 = 3t 21 = 3t 7 = t So the value of t is 7.
3t + 7 = 2t - 5 3t = 2t - 12 t = -12
5t + 2 = 3t - 2t + 5 Collect like terms 5t - 3t + 2t = 5 - 2 4t = 3 t = ¾ Check: 5 x 3/4 = 3¾ + 2 = 5¾; 3x¾- 2x¾ + 5 = 5¾ QED
3t+11 = 29 3t = 29-11 3t = 18 t = 6
s = 7, t = -3
3t - 15 = -9 3t - 15 (+15) = -9 (+15) 3t = 6 3t (/3) = 6 (/3) t = 2
5-3t = 0.77 -3t = 0.77-5 -3t = -4.23 t = 1.41
6,000 pounds.
Yes.
4+3t = 22 3t = 22-4 t = (22-4)/3 t = 6
S = 3 st + 3t = 6 st = 6 - 3t s = (6 - 3t)/t = 6/t - 3
It is an equation. Taking it step by step: 17 = 3t - 4 17 + 4 = 3t 21 = 3t 7 = t So the value of t is 7.
3t + 7 = 2t - 5 3t = 2t - 12 t = -12
17
We're not at all sure what you mean by "variable number". If 0.6 = 3t, then t = 0.2 .
