Answer:
x = 3, x = 6
Step-by-step explanation:
Using the rules of logarithms
log x - log y = log ( )
log ⇔ nlog x
x = n ⇔ x =
Given
2 x - (x - 2) - 2 = 0 ( add 2 to both sides )
x² - (x - 2) = 2
( ) = 2
= 3² = 9 ( multiply both sides by x - 2 )
x² = 9(x - 2) ← distribute
x² = 9x - 18 ( subtract 9x - 18 from both sides )
x² - 9x + 18 = 0 ← in standard form
(x - 3)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 6 = 0 ⇒ x = 6
You have to find the common denominator of the fractions, which is 24. You then have to multiply each fraction so that each fraction's denominator is 24. You multiply 1/8 by 3 to give you 3/24, and multiply 1/3 by 8 to get 8/24. Then, add 8/24 on each side so that you get y by itself. You will get Y>11/24

less than always means to subtract from
1.6 hours
152 km total divided by her speed, 95 km/h =1.6
So 20% of 70 is 14
70-14 is 56
Ans 56
