Hello,

if the exact equation is

2^{1-x}=3^{2x-3}

==>(1-x)ln 2=(2x-3) ln 3

==>2x ln 3+x ln 2=ln 2 +3 ln 3

==>x=ln (2*3^3) / ln (2*3²)

==> x= ln(54)/ ln (18)

==>x ≈1,3800937....


if the equation is 2^1 -x  =3^2 *x -3 then

2-x=9x-3
==>10x=5
==>x=1/2

Dustin is buying carpet for the living room. How many square feet of carpet will he need to buy?
rusak2 [61]

Complete Question:

Dustin is buying carpet for the living room. If the length of the room is 21 ft and the width

is 11 ft, how many square feet of carpet does he need to buy?

Answer:

231 ft²

Step-by-step explanation:

==>GIVEN:

Length of room (L) = 21 ft

Width of room (W) = 11 ft

==>REQUIRED:

Square feet of carpet to be bought = area of the rectangular room

==>SOLUTION:

The room to be covered with carpet is rectangular in shape. In order to ascertain the square feet of carpet to be bought, we need to calculate the area of the room by using the formula for area of rectangle.

Thus, area of rectangle (A) = Length (L) × Width (W)

A = 21 × 11

A = 231 ft²

Square feet of carpet to be bought = 231 ft²

A house has increased in value by 34% since it was purchased the current value is 469,000 what is the value when it was purchase
Rashid [163]

Answer:

$ 710606.606

Step-by-step explanation:

Let original price be x

x - 34% of x = 469000

=> X - 34x/100 = 469000

=> 100x -34x/100 = 469000

=> 66x/100 = 469000

=> 66x = 46900000

=> X = 46900000/66

=> X = 710606.606
