It is already in standard form.
First, you combine like terms (7 and 1) so that is 8. then you are done with the answer of 8-5x
Are there choices to the answer or must you draw the graph?
If you can please attach images so I can help :)
Answer:
a) The mass of a box of bolts is greater.
b) 3/20 kg
Step-by-step explanation:
a) Firstly, you have to make the denominators of the two fractions the same (by finding the LCM of the denominators).
The LCM of 4 and 5 is 20.
Converting 3/4 into denominator 20:

= 15/20
Converting 3/5 into denominator 20:

= 12/20
Now comparing the numerators:
15 > 12
Hence,
3/4 > 3/5
b) Difference of the boxes can be done by subtracting the numbers with the same denominator:
15/20 - 12/20
= 3/20 kg
