brainly.com/question/10629871How do you calculate it? You start by expressing the density in the units you have. Then you multiply by appropriate conversion factors to get to the units you want. Treat units as though they were any other variable. A value cancels that appears in both the numerator and denominator of a fraction.

Answer:
Step-by-step explanation:
4b - 6d = 4*7 - 6*3
= 28 - 18
= 10
Answer:
no solution.
Step-by-step explanation:
1) in order to explain, the given system should be resolved:

2) the both equations have the same slope (it is 3), it means the given lines are parallel, then no solution.
Solve the equation:
– 3b – (– 2) = 4b <span>– 12
</span>– 3b + 2 = 4b – 12
– 3b = 4b – 12 – 2
– 3b = 4b – 14
– 3b – 4b = – 14
– 7b = – 14
– 14
b = ———
– 7
b = 2 <——— solution.
I hope this helps. =)
