Answer:
3 e^t/2 + 4 = 27
e^t/2 = 23 / 3
Taking natural log of both sides
t/2 = ln 23/3 = ln 7.667 = 2.037
t = 4.074
Check:
3 e^4.074/2 + 4 = 27
27 = 27
It is increasing by 3 each time
Answer:
2. 18-x-x-x = 0
x = 6
3. 35-y-y-y-y-y = 0
x = 7
4. 42-z-z-z-z-z-z = 0
z = 7

Answer:
Step-by-step explanation:
65÷b+8×4=20
Put the value of b=5 in equation
65÷5+8×4=20
According to BDMAS rule
13+32=20
45=20
Bring the terms on one side
45-20=25 Answer
