Answer:
the mass of the empty box is 4/3 kg.
Step-by-step explanation:
The total mass (box plus 4 books and 2 files) is 2 kg
When half of the load is removed (2 books and 2 files) the mass is 1 3/20.
We have the following equation:
2 kg - (x/2)= 1 3/20 kg
Where x is the total mass of the load (4 books and 2 files)
This steps where followed to solve the equation:
2 -x/2 = (20-3)/20
40-10x=17
23=10x
x=2/3 kg
That is the total mass of the load
Hence
2kg -2/3 kg= 4/3 kg, the mass of the box
Answer:
Step-by-step explanation:
Since they are consecutive angles
You would subtract 180 from 135 to get 45 Measure 2 is 45
Hello!
So, the slope is 2, which means "up 2 over 1" because of rise over run and 2 is 2/1.
You have to find the graph that as a line passing through (-2, -3), so the answer is going to be Graph D.
Hope this helps :))
Answer:
y= -21x/19 x≠0
Step-by-step explanation:
(I just reviewed this!) Combined like terms and used Pemdas for Order of Operations. Canceled out -21x with -21 and we know that x is not equal to 0. If you need more help there are some sites like Khan Academy.
