Given:

The equation is:

3^x\times 9=3^{2n-1}

To find:

The value of n in terms of x.

Solution:

We have,

3^x\times 9=3^{2n-1}

It can be written as

3^x\times 3^2=3^{2n-1}

3^{x+2}=3^{2n-1}                [\because a^ma^n=a^{m+n}]

On comparing the exponents, we get

x+2=2n-1

Add 1 on both sides.

x+2+1=2n-1+1

x+3=2n

Divide both sides by 2.

\dfrac{x+3}{2}=n

Therefore, the value of n is terms of x is n=\dfrac{x+3}{2}.

During the school year, a bus driver made 7 trips to the museum. The distance from the school to the museum is 36 miles. Write a
bagirrra123 [75]

Given:

Number of trips = 7

Distance from the school to the museum = 36 miles.

To find:

Write and solve equations to find how many miles the bus driver drove for the 7 trips.

Solution:

Let x be the number of trips and y be the total number of miles the bus driver drove.

Distance from the school to the museum = 36 miles.

1 trip means from the school to the museum and then from the museum to the school.

Distance covered in 1 trip = 2×36 = 72 miles.

Distance covered in x trips = 72x miles.

y=72x

Substitute x=7 in the above equation to find the total distance the bus driver drove for the 7 trips.

y=72(7)

y=504

Therefore, the bus driver drove 504 miles for the 7 trips.
