What value of x is in the solution set of 2(3x – 1) = 4x - 6?
Andrei [34K]

Answer:

x=-2

Step-by-step explanation:

2(3x – 1) = 4x - 6

Distribute

6x-2=4x-6

Moving like terms (4x)

2x-2=-6

Moving like terms (-2)

2x=-4

Divide both sides by 2 to isolate x

x=-2

Answer:

8450 = P

Step-by-step explanation:

I = Prt

Where I is the interest , p is the principle, r is the rate and t is the time in years

2078.70 = P *8.2% * 3

Changing to decimal form

2078.70 = P *.082 * 3

2078.70 = P *.246

Divide each side by .246

2078.70/.246 = P *.246/.246

8450 = P

Solve each exponential equation by using properties of common logarithms. When necessary, round answers to the nearest hundredth
lisabon 2012 [21]

Answer:

0.08

Step-by-step explanation:

Please use parentheses to indicate which operations must be done first.  I 'm choosing to believe that you meant 7^(3x-1) and 5^(x-1).

Taking the common log of both sides, we get:

(3x-1)log 7 = (x-1)log 5

Then 3x·log 7 - log 7 = x log 5 - log 5

Grouping the x terms:

x(3·log 7 - log 5) = log 7 - log 5.  We combine log 7 and log 5, obtaining log (7/5).

Then x(3·log 7 - log 5) = log (7/5).

Solving for x:

      log (7/5)

x = ---------------------

      3·log 7 - log 5

        0.1461

x   = ------------- = 0.08

         1.0363

This agrees with the 3rd answer choice.
