I'm going to say 3 1\2. Let me know when you get the answer.
390-35=355
355-10w
355/10=35.5
355-10(35.5)
35 and a 1/2 weeks
36 weeks to have the full amount needed
1.8k kilometers is needed to make 3 boxes
ANSWER
1a)
The given system of equation is:
and
We make x the subject in equation (2) to get;
We put equation (3) into equation (1) to get;
We expand the bracket to get,
This implies that,
This statement is false.
Hence the system has no solution.
1b)
Let us write the two systems in the slope-intercept form;
For the first equation, we have
Thus implies that,
For the second equation, we have:
We can see that, the two equations are parallel since they have the same slope.
Also the two equations will never meet since they have different y-intercepts.
Hence the system has no solution.
Answer:
d=7/2
Step-by-step explanation:
3/4d-1/2=3/8+1/2d
multiply all by 8, to make them into whole numbers (makes it easier)
6d-4=3+4d
move terms
6-d-4d=2d
3+4=7
7=2d
d=7/2
