Can anyone explain the method for algebraic fraction? We have to do it for maths, and i'm really struggling with it. Here is an

riadik2000 [5.3K]

Answer:

x=3

Step-by-step explanation:

The approach is not very different from regular fractions.

You have to get to a common denominator to be able to add them.

10 is a good denominator (multiply the denominators).

multiply the first term by 5, and the second one by 2:

$\frac{5 \cdot (x+1)}{5 \cdot 2} + \frac{2 \cdot (x+2)}{2 \cdot 5} = 3$

$\frac{5x+5 + 2x+4}{10} = 3$

$\frac{7x+9}{10} = 3$

7x + 9 = 30

7x = 30 - 9

x = 3

let me know if you need more details on one of the steps

A lunch bill is $12 before tax. If the tax on the bill is 7.5% what is the total cost of the lunch including tax?

nikitadnepr [17]

Answer:

$\boxed{ \bold{ \huge{\boxed{ \sf{ \: 12.9 \: \: dollars}}}}}$

Step-by-step explanation:

Given,

Cost without tax = $ 12

Tax percent = 7.5 %

Cost including tax = ?

First, finding the tax amount :

$\sf{tax \: amount \: = \: 7.5 \: \% \: of \: 12}$

⇒ $\sf{tax \: amount = \frac{7.5}{100} \times 12}$

⇒ $\sf{tax \: amount = 0.9}$ dollars

Finding the total cost of the lunch including tax :

⇒ $\sf{total \: cost \: = \: 12 + 0.9}$

⇒ $\sf{total \: cost \: = \: 12.9}$ dollars

Hope I helped!

Best regards ! :D
