Lydia received her salary on friday. she spent one-half of her salary on rent and then spent $168 on her electric and water bill. next she spent one-half of what was left on her phone bill. after spending $57.00 on gas for her car, lydia had $92.00 left. how much did lydia spend on rent?

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
