Answer:

x=\frac{(a^2+ab)}{a-b}

Step-by-step explanation:

So we want to make x the subject of the formula:

a(x-b)=a^2+bx

First, distribute the left side:

a(x)-a(b)=a^2+bx\\ax-ab=a^2+bx

Combine all the terms with x with it on one side. To do this, first subtract bx from both sides. The right side cancels:

(ax-ab)-bx=(a^2+bx)-bx\\ax-ab-bx=a^2

Remove the -ab from the left. Add ab to both sides. The left side cancels:

(ax-ab-bx)+ab=a^2+ab\\ax-bx=a^2+ab

Now, distribute out the x from the left side:

ax-bx=a^2+ab\\x(a-b)=a^2+ab

Divide both sides by (a-b). The left side cancels:

\frac{(x(a-b))}{a-b}=\frac{(a^2+ab)}{a-b}  \\x=\frac{(a^2+ab)}{a-b}

Therefore:

x=\frac{(a^2+ab)}{a-b}

Answer:

Step-by-step explanation:

ax -ab = + bx

collect like terms

ax-bx= +ab

factorise

x(a-b)=a(a+b)

x=\frac{a(a+b)}{a-b} or \frac{a^{2} + ab}{a -b}

Answer:

44%

Write 12 1/3 as an improper fraction.
Julli [10]

Answer:

\frac{37}{3}

Step-by-step explanation:

12\frac{1}{3}

When converting mixed numbers (such as the one above), to improper fractions, we must first multiply the whole number by the denominator:

12*3=36

Then, add the numerator the the product:

36+1=37

Now, put the sum over the denominator to get your solution:

\frac{37}{3}

-

To check your work, you can convert the improper fraction to a mixed number to make sure you will end up with 12\frac{1}{3}.

Divide 37 into 3:

12 with a remainder of 1

Put the remainder over the denominator:

12\frac{1}{3}

Therefore, our solution is correct!
