Answer:
x = -1 ; y=4
Step-by-step explanation:
1. Use the substitution method and replace the <em>y</em> on the second equation with the first equation,
2. Solve for <em>x</em> (x=-1)
3. Plug <em>x</em> into the first equation to get <em>y</em>
<em />
<u><em>ANS: y=4</em></u>
Answer:
1020–1029 kg/m3
Step-by-step explanation:
The density of seawater at the surface of the ocean varies from 1,020 to 1,029 kilograms per cubic meter.
The density of seawater is a function of temperature, salinity, and pressure.
To measure the density of ocean water a sample of sea water is collected and brought into the laboratory to be measured. Salinity, temperature and pressure are measured to find density. The formula for measuring density is p(density) = m(mass) / V(volume).
