Answer:
-1.25 =x
Step-by-step explanation:
-5x + 10 = -13x
Add 5x to each side
-5x + 10+5x = -13x+5x
10 = -8x
Divide by -8
10/ -8 = -8x/-8
-5/4 =x
-1.25 =x
Answer:
50 total penguins
Step-by-step explanation:
In the following example x = the total number of penguins.
Set it up as follows.
15 over x = 30 over 100
Cross multiply the numbers. (30 times x) and (15 times 100)
This results in 30x = 1500.
Divide both sides by 30 which results in x = 50.
This means that there is a total of 50 penguins.
In the following example x = the number of Emperor penguins.
If you would like to double check this, set up as follows.
x over 50 = 30 over 100
Cross multiply the numbers. (30 times 50) (100 times x)
This results in 100x = 1500.
Divide both sides by 100 which results in x =1 5.
This means that there are 15 Emperor penguins.
I believe it's 23 as your answer
