Let
x---------> <span>quantity (ton) of vegetables sold the first day
</span>y---------> quantity (ton) of vegetables sold the second day
z---------> quantity (ton) of vegetables sold the third day
we know that
x=y-3---------> equation 1
z=(5/9)*(x+y)------> equation 2
x+y+z=98-----> equation 3
substitute equation 2 in equation 3
x+y+[(5/9)*(x+y)]=98----> multiply by 9----> 9x+9y+5x+5y=882
14x+14y=882-----> equation 4
to resolve the equations system formed by
x=y-3
14x+14y=882
using a graph tool
see the attached figure
the solution is
x=30
y=33
x+y+z=98----> z=98-(x+y)----> z=98-63---> 35
the answer is
vegetables sold the first day----> 30 tonvegetables sold the second day----> 33 tonvegetables sold the third day------> 35 ton
Do you think it could be 'rho' (density)? Like the thing you use for calculating pressure in fluids?
...or maybe it's just a fancy P.
Answer:
D
Step-by-step explanation:
Here, we want to know which of the options would be true if we replace the term in the box ( D) by the value 1,537.
The correct option here is thus D
What we have here would be
1537 > 1,357
This can be read as 1537 is greater than 1,357 which is correct
Common denominator = 40
36/40 + 20/40 = 56/40
Reduce and simplify=
7/5, which is 1 and 2/5
Hope that helps
