Three rectangular tables are placed end to end to form one long table 7.8 meters long. the lengths of two of the tables are 3.5 meters and 1.6 meters. what is the length of the third small table? what type of problem is this, and why? a part-whole problem, because 3.5 is a part of 1.6 a part-whole problem, because the length of the third table is part of the total length of the long table a comparison problem, because 7.8 is being compared to 3.5 a comparison problem, because the question asks how much longer one smaller table is than the other

It's a 3rd grade problem in addition and subtraction, or number lines. As a college-level problem, it might be described as ...

... a part-whole problem, because the length of the third table is part of the total length of the long table

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
