Solve. 3^x+1 = 9^ 5x a. x=3 b. x = 1/3 c. x=9 d. x= 1/9

jasenka [17]

Answer:

x = 1/9

Step-by-step explanation:

3^ (x+1) = 9 ^ (5x)

Replace 9 with 3^2

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

We know that a^b^c = a ^(b*c)

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

3^ (x+1) = 3^(10x)

The bases are the same so the exponents are the same

x+1 = 10x

Subtract x from each side

x+1-x = 10x-x

1 = 9x

Divide each side by 9

1/9 = 9x/9

1/9 =x

Debora [2.8K]

Answer:

The Number sentence 36 ÷ 3 will be used to find number of guest invited in Ryan dinner.

There were 12 guests invited to Ryan's dinner.

Step-by-step explanation:

Given:

Total Number of pieces = 36 pieces.

Also Given:

Ryan set a table with a fork, knife, and spoon for each dinner guest.

From above we can conclude that;

Number of Piece for each Dinner guest = 3 piece.

We need to find the number of guest invited in Ryan dinner.

number of guest invited in Ryan dinner will be equal to Total Number of pieces used for guest divided by Number of Piece for each Dinner guest.

framing in equation form we get;

number of guest invited in Ryan dinner = $\frac{36}{3}=12 \ guest$

Hence The Number sentence 36 ÷ 3 will be used to find number of guest invited in Ryan dinner.

Also There were 12 guests invited to Ryan's dinner.
