Din cantitatea de 30l de lapte 1 pe 5 este folosita pentru budinca,1 pe 3 pentru cacao cu lapte, iar restul pentru desertul de la ora 17: 00. cati litri de lapte s-au folosit la desert?

This is the concept of algebra, we are required to find the amount of milk used for dessert given that we initially had 30 l of milk, given that 1/3 was used for pudding, 1/5 was used for cocoa and the rest for dessert. 
The initial amount of milk is represented by fraction 1/1. The remaining amount of milk will be given by:
[initial fraction of milk]-[total fraction of milk used]
fraction of milk used was:
1/5+1/3=8/15
Therefore the remaining fraction was:
1/1-8/15
=7/15
Thus the amount that was used for dessert was:
7/15of 30
=14 l.
The answer is 14 l

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
