Answer:
9g/mL
Step-by-step explanation:
The density of something is mass/volume and the density of something never changes, no matter how much or how little there is of it.
We know that the mass of Cu (copper) is 45g and its volume is 5.0mL.
density = 45g/5.0mL
Plug that into a calculator and you'll get your answer.

Answer:
22) 119
24) 15
Step-by-step explanation:
22) 61 + b = 180 <-- supplementary because on the same line
b = 119 <-- subtracted 61 from both sides
24) 87 + (6x + 3) = 180 <-- supplementary because on the same line
87 + 6x + 3 = 180 <-- take out parantheses
90 + 6x = 180 <-- add like terms
6x = 90 <-- subtracted 90 from both sides
x = 15 <-- solve for x by dividing 6 from both sides
