The grid lines will help you find an exact solution (assuming the two lines actually cross at a grid intersection point). However, the two lines may intersect somewhere off the grid lines which is when an estimation will be the next best thing.
If your trying to find the original amount all you have to do is add the 12 to the 52 to find out, that is 64!
Here is the website for the answer... I hope this helps...
P.S. I think that if you click on the link, it won't work. So, just copy and paste...
23=5-2y
Get y alone,
23-5= 18
18= -2y
Divide to find y
18/-2=-9
Y= -9
Or since you asked for x, X=no solutions.
Hope it helps ❤️
Answer:
The first piece is 5 inches long, while the second is 15 inches and the third one is 20 inches.
Step-by-step explanation:
To determine the length of the 3 pieces, knowing that the total of the board is 40 inches, and that the second measures 3 times more than the first and the third measures 4 times more than the first, the following equation must be performed:
X + 3X + 4X = 40
8X = 40
X = 40/8
X = 5
Therefore, the first piece is 5 inches long, while the second is 15 inches and the third 20 inches.
