Answer:

Step-by-step explanation:
We have to simplify the given exponential exponents.
Exponential Properties:
Simplification takes place in the following manner:
a)

b)

c)

d)

200,000 = 158,000(1.06)^x
Divide both sides by 158,000
1.2658 = 1.06^x
Take the log of both sides and use the power rule to bring down the exponent (x) to the front.
log 1.2658 = x log 1.06
Divide both sides by log 1.06
log (1.2658)/log(1.06) = x
x = 4 years
CHECK
y = 158,000(1.06)^4
y = 199,471.36
I believe the answer is 7
1kg = 1000g
4 apples = 1000g
1 apple = 1000/4
1 apple = 250g
Answer:
X=9
Step-by-step explanation:
2x-7=11
Add 7 each side
2x - 7 +7 =11 + 7
2x=18
Divide by 2 each side
2x/2=18/2
x=9
