Answer:
21
Step-by-step explanation:
Chickens - 2x
cows - 4x
goats = 4x
2x+4x+4x+210
10x=210
x=21
CHECK:
21 chickens = 42 legs
21 cows = 84 legs
21 goats = 84 legs
42+84+84=210 legs
Answer:
x=66
Step-by-step explanation:
Every triangle is equal to 180 degree angles so if you do 83+31, then that is equal to 114, which is when you do 180-114 and that would be 66. So your answer would be x=66
Answer: X = -5
Step-by-step explanation:
3(x-5)=2(x-10)
3x - 15 = 2x -20
3x = 2x -5
x = -5
Log₄(y+2) = 3, transform it into exponent form:
(y+2) = 4³
y+2 = 64
y= 62
