Select the equation that has the same solution as the equation below.<br> 5^(2x-5)= 125
Ahat [919]

The equation that has the same solution as 5^{(2x-5)} = 125 is: C.64 = 2^{(3x - 6)}

<h3>How to Solve Equations having Exponents</h3>
  • To solve such, simplify the bases so that the base on the right equals the base on the left.
  • Then solve the equation for the variable.

Given:

5^{(2x-5)} = 125\\\\5^{(2x-5)} = 5^3\\

  • The bases will cancel out

2x - 5 = 3

  • Solve for x

2x = 3 + 5

2x = 8

x = 4

The solution of 5^{(2x-5)} = 125 is 4.

Thus:

64 = 2^{(3x - 6)}\\\\2^6 = 2^{(3x - 6)}\\\\6 = 3x - 6\\6 + 6 = 3x\\12 = 3x\\4 = x\\x = 4

Therefore the equation that has the same solution as 5^{(2x-5)} = 125 is: C.64 = 2^{(3x - 6)}

Answer:

  24 miles

Step-by-step explanation:

The total fare is the sum of the pickup fee and the mileage charge. For xx miles, the mileage charge will be 1.75xx, so the total is ...

  1.75xx +2.90 = 44.90 . . .  equation for xx

  1.75xx = 42.00 . . . . . subtract 2.90

  xx = 24 . . . . . . . . . divide by 1.75

The number of miles in Nicole's taxi ride was 24.
