Answer:
t = 350
Step-by-step explanation:
subtract 250 from each side, and then you'll have t = 350
Step-by-step explanation:
15t + 30 = 20t | -15t
30 = 5t
t = 30/5 = 6
20 + 5t = -6t + 86 | + 6t
20 + 11t = 86 | -20
11t = 66
t = 6
18t + 20 = 24t + 50 | -18t
20 = 6t + 50 | -50
-30 = 6t
t = -30/6 = -5
18t - 2 = 10t + 54 | -10t
8t - 2 = 54 | +2
8t = 56
t = 56/8 = 7
7t - 5 = 15t + 91 | -7t
-5 = 8t + 91 | -91
-96 = 8t
t = -96/8 = -12

Answer:
Step-by-step explanation:
A. In this case, they can be arranged at any order. Since there are 7 people all in all, therefore the number of arrangements is:
number of arrangements = 7P7 = 5040 ways
B. In this case, only the 5 people can be arranged in any order therefore 5P5. However the groom and bride can be interchanged on 2 places, therefore:
number of arrangements = 5P5 * 2 = 240 ways
C. In this case, only the 5 people can be arranged in any order while the groom and bride can no longer be interchanged, therefore:
number of arrangements = 5P5 = 120 ways
