Ilya [14]

Answer:

  37.5% decrease

Step-by-step explanation:

  pct change = ((new price) -(original price))/(original price) × 100%

  = (50 -80)/80 × 100%

  = -3/8 × 100% = -37.5%

The negative sign indicates a decrease.

The decrease in price is 37.5%.

Find the value of x if 9^1/2 • 9^1/2 = x^√81
mario62 [17]

Answer:

(√9)^2x-1/2 = 1/81

3^2x-1/2 = 1/(3)⁴. (as √9 = 3)

3^2x-1/2 = 3^-⁴. (as 1/a^m = a^-m)

as base are equal exponents are equal

so 3 gets cancelled out

2x-1/2 = -4

(4x-1)/2 = -4

4x-1 = -8

x = -7/4

hope this helps
