Answer:

=1050 wildebeests

Step-by-step explanation:

We can form an arithmetic series for the wildebeest migration.

Sₙ=n/2(2a+(n-1)d) where  n is the number of terms, d is the common difference and a is the first term.

a=24

n=20

d=3

Sₙ=(20/2)(2(24)+(20-1)3)

Sₙ=10(48+57)

=1050 wildebeests

Solve the following system of equations by using the substitution method.
Hatshy [7]
X = y + 3
2x + y = 9

Solution..
---------------

Substitute for x=y+3 in the second equation...

2x+y = 9

2(y+3)+y=9

2y+6+y=9
3y+6=9
3y=9-6
3y=3
y=3/3
y=1....

Substitute for y=1 in the first equation...

x=y+3

x = 1+3
x=4..

Am sure the answer is quite evident now...
