When you need to find the blank and get a explanation you should you solve for x calculator it’s easier that way
A parallelogram has 4 sides.
So, we divide 72, the meters of the parallelogram. = 18
Now, the length is 4 more, so we add. 18+4=22
The length is 22.
Now, both lengths are 22, so double is 44; subtract 44 from 72. 72-44=28
In conclusion, we divided 28 by 2 to get the width of both sides.28/2=14
The width is 14.
Answer:
20
Step-by-step explanation:
The first equation is 50 - 2x (because you start with $50 and subtract 2 for each 30 day period)
The second equation is 40-1.5x
Set them equal to each other: 50 - 2x = 40 - 1.5x
Solve for x:
50 - 2x = 40 - 1.5 x
+2x +2x
-----------------------
50 = 40 + 0.5 x
-40 -40
-------------------
10 = 0.5 x
20 = x
So there will be 20 30-day periods until the cards will be equal in value.
Check: After 20 periods, 50 - 2(20) = $10 left
40 - 1.5(20) = also $10 left
There's two possible ways to find the answer to this. First you can find a common denominator to reduce both to. In this case, they can both reduce to a common denominator of 8. So 6/16 reduces to 3/8 and 30/80 also reduces to 3/8, so they are equal. The other way is to use a calculator and turn them into decimals by dividing the numerator by the denominator. They both come out to be .375. Once again they are equal. You can use whichever method is easier for you.
