Answer:
x = 16
Step-by-step explanation:
12(x - 20) = -48
Use distributive property
12*x - 12*20 = -48
12x - 240 = -48
Add 240 to both sides
12x = -48 + 240
12x = 192
Divide both sides by 12
x = 192/12
x = 16
The answer is the first one or -10
18. -4, 4
19. -38, 38
20. -260, 260
21. -4092, 4092.
I might be wrong but...
Hello!
To start, first consider your given information. The elephants are fed 2 1/10 barrels of corn every day. The buffalo are fed 1 1/5 times that amount.
Now, the question then asks to find the amount the buffalo are fed. The amount they are fed can be represented by this expression:
2 1/10*1 1/5
Because the fractions are mixed, turn then into improper fractions (multiply the whole number to the denominator and add that to the numerator; the denominator remains the same).
When you convert both fractions to an improper fraction you should get this:
21/10*6/5
Now, multiply straight across the numerator and denominator:
21*6/10*5
This would result in 126/50
However, you must first simplify this fraction by dividing the numerator and denominator by their greatest common factor. This would be 2.
When you divide both sides by 2, you should get 63/25. Now convert this back to an improper fraction and you get
2 13/25 as your answer.
Hope this helps!
