How to combine fractions 5b/4a+b/3a-3b/a
Step2247 [10]
Most importantly, while including divisions with various denominators, the initial step says that we should change these portions so they have "a similar denominator" .Here are the means for including divisions with various denominators .Construct each portion with the goal that the two denominators are equivalent. Keep in mind, while including divisions with various denominators, the denominators must be the same. So we should finish this progression first. <span>a.         Re-compose every proportionate division utilizing this new denominator </span> <span>b.         Now you can include the numerators, and keep the denominator of the proportionate divisions. </span> <span>c.         Re-compose your answer as a streamlined or decreased division, if necessary. </span> We know this sound like a great deal of work, and it is, yet once you see completely how to locate the Common Denominator or the LCD, and manufacture proportional parts, everything else will begin to become all-good. Thus, how about we set aside our opportunity to do it.   Solution: 5b/4a + b/3a -3b/a =15b/12a + 4b/12a – 36b/12a = -17b/12 a Or <span>= - 1   5b/12a  in lowest  term.

Long rationalise surds questions <br>pls help​
Katena32 [7]

Answer:

Noah mistakenly added 25 and 7 in denominator instead of subtracting in the third step.

Step-by-step explanation:

Noah had to rationalize the denominator of \frac{32}{5-\sqrt{7}}

According to him,

\frac{32}{5-\sqrt{7} = \frac{32(5+\sqrt{7}{(5-\sqrt{7})(5+\sqrt{7}

Solving the nominator and denominator

= \frac{160-32\sqrt{7}}{25+5\sqrt{7}-5\sqrt{7}-7}

Noah did correctly till this point.

In the next step he add 25 and 7 in the denominator, whereas, it should be subtracted.

Hence,

Noah mistakenly added 25 and 7 in denominator instead of subtracting in the third step.

This week laptops are 25% off. If a laptop costs $340, what is its sale price?
Alexandra [31]

____________________________________________________

Answer:

Your answer would be $255

____________________________________________________

Step-by-step explanation:

To solve these kind of problems, what we have to do is find how much of 340 is 25%, and then subtract that number to the original price.

Let's give you some important information in the text:

  • 25% off
  • $340

With the information above, we can solve our problem.

First, we would need to find how much of 340 is 25%, and to do that, we would multiply 340 by 0.25:

340*0.25 = 85

When you solve, you should get 85. But, you're not done yet, we need to find out how much the sales price is, not how much of it is discounted.

In order to find the sales price, we would get our original number (the number it originally cost), and subtract it with the amount of money it's removing (85).

In this case, we would subtract 340 by 85.

340-85=255

Your FINAL answer should be 255

The sales price of the laptop would be $255.
