Answer:
There are 7 Pigs and 6 Chickens
Step-by-step explanation:
Let's assume
Pigs= x
Chicken=y
(eq 1) x+y = 13----------y=13-x
4x + 2y = 40
replace the y
4x+ 2(13-x) = 40
you get x = 7
replace x in y=13 -x
you get y = 6
hence the answer.
Up to 2 integers can have the same absolute value (a number and its opposite).
For example, 2 and -2 have the same absolute value. 5 and -5 also have the same absolute value.
Answer:
Step-by-step explanation:
18x + 9 = -3x + 13
21x + 9 = 13
21x = 4
x = 4/21
The degree is 4, because it has 4 zeros.
