Answer: $135
Step-by-step explanation: x(40/100)=54. x represents the original price and 40/100 is the discount while 54 is the money saved from the discount. This ultimately shows us 40% of something is 54 and that something is represented by x and x equals 135.
Answer:
c is the answer
Step-by-step explanation:
Let's explain this by using an example. Let's take the square root of 4.
sqrt(4)
You'd think the answer is 2, and you are correct, but the answer is also -2.
Remember that a square root means that the two numbers must be the same, and multiply back up to 4. In this case, the number is 2.
2•2=4
BUT
-2•-2 ALSO =4
therefore there are two square roots...
2 is a square root
AND
-2 is a square root.
This goes with all positive numbers!
I hope this helps! Best wishes :)
<u>Answer: </u>14x - 11y
<u>Step by Step Explanation: </u>
- Ignoring that first half, your first step is to distribute the subtraction sign
-(-5+9y-8x) —-> 5-9y+8x
- Next, combine like terms
- Your x terms, y terms, and regular numbers
6x-2y-5+5-9y+8x
6x+8x-2y-9y-5+5 (reorganizing terms so that they’re together can be helpful for some people, but it’s not necessary)
6x+8x = 14x, -2y-9y = -11y, -5+5 = 0/Cancel each other out
This leaves you with 14x-11y
sure
first convert 33ft to inches
33 x 12 = 396 inches
then do 396-9.75 = 386.25in
to convert to ft, simply divide this answer by 12
32.1875 ft
