Answer:
0x2+9x-3x-27 6x-27
Step-by-step explanation:
The answer will be 2/25 times 1/175 which would equal 14/1
Therefore, the answer is: the model car will be 14 inches long.
3/5 is equal to 6/10 - always find a common denominator
So then you can easily add 1/10+6/10 which equals 7/10
I believe x=25 and y=10.
Step-by-step explanation:
Because we know the angles in a parallelogram add up to 360 degrees, we can add up values and divide to find x and y. 8y and 4x-20 are supplementary, they must equal the same value. Same with 10y and the other corner. By this, we can do 10y times 2 and 8y times 2 to get 16y plus 20y, or 36y. Then, we divide 360 degrees by 36. We get y=10 from this. Plug in 10 to 8y and get 80 as the upper left angle measurement. This means that 4x-20 equals 80. Add 20 to 80 on both sides so it cancels out and you get 100=4x. Simply divide and you will get x=25. To make sure this is right, plug all the numbers in and make sure all of the angles add up to 360. Hope this helps :)
Answer:
Step-by-step explanation:
Givens:
- There are 24 inches of ribbon per spool.
- Margaret needs 384 inches of ribbon.
If we think about it, we realize that we need to divide all 384 inches of ribbon by 24 inches, which represents each spool. This division is what is going to give us the number of spools.
Another way to solve this, it's using the rule of three, if one spool is 24 inches, how many spools would get form 384 inches:
So, the number of spools would be 16.
If you want only the expression it would be
