Answer:
IT HAS TO BE B
Step-by-step explanation:
X+y=41
2x-3y=12
27+14=41
2•27-3•14=12
x=27
y=14
Answer:
d + c = 12
d = 2c - 3
Step-by-step explanation:
Given that :
Total number of dogs and cats = 12
Let :
Dogs = d ; Cats = c
d + c = 12
Number of dogs = 2 times the number of cats less than 3 ;
Mathematically,
d = 2c - 3
The answer is y= 3/4x - 4.
There are 720 ways.
That's because there are 10 ways for someone to be first, 9 ways for someone to be second after him, and 8 for someone to be third after them, so 10 x 9 x 8 = 720.
