Whates 2 divided by 3 z= -6

Mathematics

z = 20/3 = 6.667

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2/3-(z-6)=0

Step by step solution :

Step 1 :

2

Simplify —

3

Equation at the end of step 1 :

2

— - (z - 6) = 0

3

Step 2 :

Rewriting the whole as an Equivalent Fraction :

2.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 3 as the denominator :

z - 6 (z - 6) • 3

z - 6 = ————— = ———————————

1 3

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2 - ((z-6) • 3) 20 - 3z

——————————————— = ———————

3 3

Equation at the end of step 2 :

20 - 3z

——————— = 0

3

Step 3 :

When a fraction equals zero :

3.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

20-3z

————— • 3 = 0 • 3

3

Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

20-3z = 0

Please help me out !!! <br><br> *please answer asap*
mariarad [96]

Answer:

h(-3) = -5

Step-by-step explanation:

h(-3) = -I 2-(-3) I

Two negatives makes a positive: -(-3) = +3 or 3

h(-3) = -I 2+3 I

h(-3) = -I 5 I

*There is a negative that lies outside of the absolute value lines, which makes everything positive.

Making sure the 5 is positive, remove the absolute value lines.

h(-3) = - +5

The negative sign is still there.

A negative and a positive makes a negative.

h(-3) = -5

You purchased a rare painting for $150 that is increasing in value by 3% annually. How many years will it take until it is doubl
Ahat [919]

Answer:

23 years.

Step-by-step explanation:

It is given that the initial price of painting is $150 and its values increasing by 3% annually.

We need to find how many years will it take until it is doubled in value.

The value of painting after t years is given by

y=150(1+0.03)^t

y=150(1.03)^t

The value of painting after double is 300. Substitute y=300.

300=150(1.03)^t

Divide both sides by 150.

2=(1.03)^t

Taking log both sides.

\log 2=\log (1.03)^t

\log 2=t\log (1.03)

t=\dfrac{\log 2}{\log (1.03)}

t=23.44977

t\approx 23

Therefore, the required number of years is 23.
