Answer:

H = 58, I = 71, J = 51

Step-by-step explanation:

Set all angles equal to 180

3x - 2 + 4x - 9 + 3x - 9 = 180

Then combine like terms

10x - 20 = 180

      + 20  + 20

10x = 200

/10     /10

x = 20

Then plug in for each angle

3 (20) - 2 = 58

4 (20) - 9 = 71

3 (20) - 9 = 51

The ratio of lions to elephants in the southern region of africa is 5 to 12. The total number of lions and elephants in the sout
Talja [164]

Answer:

lions=105  elephants=252

Step-by-step explanation:

We know that there is a total of 375 lions and elephants. We also know the ratio of those. With these two we can build an equation that gives us the exact number of each of the two species.

We can multiply the ratio by x:

(5/12)*(x/x)

now we have:

5x/12x

we input these new data into the total number of both animals:

5x+12x=357

17x=357

x=357/17

x=21

remember x is not the number of any of the animals

number of lions is 5x=5*21=105

number of elephants is 12x=12*21=252
