During one year, seven coyotes in a population die. Eight immigrate into the population, but none emigrate. If the overall population growth is 13 coyotes, what was the birth rate of coyotes during the year? Use this formula: population growth = (birth rate + immigration) – (death rate + emigration) 7 11 12 15

Death rate= 7 coyotes

Immigration= 8

Emigration= 0

Population growth= 13

Let’s suppose that the birth rate for the given population is x.

Population growth = (birth rate+immigration) - (death rate+emigration)

13=(x+8)-(7+0)

13=x+1

Move the variable to the left side and change its sign.

-x+13=1

Move the constant to the right side and change its sign

-x=1-13

-x=-12

x=12

x=12

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
