Answer:142
Step-by-step explanation:
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:
4.12
Step-by-step explanation:
its 4.12 mark me brainiless
2(m-10) + 2 = 24
2m - 20 + 2 = 24
2m - 18 = 24
2m - 18 (+18) = 24 (+18)
2m = 42
2m/2 = 42/2
m = 21
hope this helps
