Answer:

$163.8

Step-by-step explanation:

We need to first make the 30% into a decimal. So it will be 0.30.

Then you need to multiply the 0.30 into 126  {  126 x 0.30 }

Which gives you 37.8

Then to fin the original you will need to add the $37.8 to $126

Which is $163.8

Since the discount price was $37.8 and they deducted that from the original price which gave you $126 the question said.

Check : <em>$126 + $37.8 = $163.8</em>

Answer:

$180

Step-by-step explanation:

Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:

\frac{126}{x}=\frac{70}{100}

Solve for the original price by cross multiplying numerator with denominator.

x(70) = 126(100)

70x = 12600

x= $180

46: 24a+40

First we are going to take a look at a) 8(3a+5)

a) We then simplify it by multiplying the numbers inside the parenthesis by 8.

a) 24a+40

Now we ask ourselves, is this equivalent to 24a+40? YES! 

So your answer for #46 is a)   8(3a+5)

What is the difference? x+5/x+2-x+1/x2+2x
Mrac [35]

Question

x+5/x+2 - x+1/x²+2x

Answer:

= (x² - 4x - 1)/[x (x+2)]

= (x² - 4x - 1)/[x² + 2x]

Step-by-step explanation:

x + 5/x + 2 - x + 1/x² + 2x

We factorise the second denominator to give us :

x + 5/x + 2 - x + 1/x(x + 2)

We find the L.C.M of both denominators which is x(x+2).

[x(x + 5)-(x + 1)] / (x (x + 2))

Expand the bracket

=[x² +5x - x -1] / [x (x + 2)]

=(x² - 4x - 1) / [x (x + 2)]

= (x² - 4x - 1)/ [x (x + 2)]

= (x² - 4x - 1) / [x² + 2x]

$132.55-($15*12)=$132.55-$180=$-47.45
So then he would have owed 47.45 dollars!
