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

Solve for X<br><br> 4X-(9-3X)=8X-1
Nataliya [291]
4x - (9 - 3x) = 8x - 1

4x - (9) - -(3x) = 8x - 1

4x - 9 + 3x = 8x - 1

7x - 9  = 8x - 1        (-8x from each side)

-x - 9 = -1                (+9 to each)

-x = 8                     (divide -1 from each side)

x = -8

A piece of string is 42 meters long. It is cut into three pieces so that one piece is 15 meters longer than the other two, which
Semmy [17]
To start this problem, we know that one of the three pieces that the string is cut into is 15 meters longer than the others. Subtract 15 from 42 to get 27.
Then, from there, you can cut that number (<em>divide</em>) by three to get the length of the two shorter strings. Simply add the 15 meters you didn't use yet to one of the pieces to find the longer string, and you have your lengths.

Hope this helps!
