Answer:

x = 4

Step-by-step explanation:

You have to remember the "Quotient Rule" for exponent having same base.

The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents.

Here,

base = 3

exponents = 2x + 1 , x + 5

   

3^(2x + 1) = 3^( x + 5)

3^(2x + 1) / 3^(x + 5) = 1

3^((2x + 1) - (x + 5) )= 1

3^(2x + 1 - x - 5) = 1

3^(2x - x +1 - 5) = 1

3^(x - 4) = 1

log 3^(x - 4) = log(1)

(x - 4) (log (3)) = 0

log(3) = 0 rejected

x - 4 = 0 accepted

x = 0 + 4

x = 4

Answer:

Choice C is the answer.

Step-by-step explanation:

We have given a equation.

3^{2x+1}  = 3^{x+5}

We have to find the value of x.

Since, we know that same bases have equal powers.

2x+1 = x+5

Adding -x-5 to both sides of above equation, we have

2x+1-x-5 = x+5-x-5

x-4 = 0

x = 4 which is the answer.

Joe wants to rent an apartment with an initial monthly rent of $1,400. He has been told that the landlord raises the rent 1.25%
nadya68 [22]

Answer: his pay for the 4th year is $1453.16

Step-by-step explanation:

The landlord raises the rent 1.25% each year. It means that the rent is increasing in geometric progression.

The formula for determining the nth term of a geometric progression is expressed as

Tn = ar^(n - 1)

Where

a represents the first term of the sequence.

r represents the common ratio.

n represents the number of terms.

From the information given,

a = $1,400

r = 1 + 1.25/100 = 1.0125

n = 4 years

The 4th term(year), T4 is

T4 = 1400 × 1.0125^(4 - 1)

T4 = 1400 × 1.0125^3

T4 = $1453.16

A total of 708 tickets were sold for the school play they were either adult tickets or student tickets there were 58 more studen
zhenek [66]
X = adult tickets and x+58 = student tickets

Create the equation from the problem.
x + x + 58 = 708

Combine like terms.
2x +58 = 708

Subtract 58.
2x = 650

Divide by 2.
x = 325

Therefore, your answer is:
there were 325 adult tickets sold.

(Adding 58 to that number will get you the student tickets sold which is 383 if they ask.)
