Answer:there were 23 birds and 4 cats
Step-by-step explanation:
Let x represent the number of birds at the shelter on Thursday.
Let y represent the number of cats at the shelter on Thursday.
Maya found a record showing that there were a total of 27 birds and cats on Thursday. This means that
x + y = 27
An animal shelter spends $2.00 per day to care for each bird and $6.00 per day to care for each cat. Maya noticed that the shelter spent $70.00 caring for birds and cats on Thursday. This means that
2x + 6y = 70 - - - - - - - - - - - - - - 1
Substituting x = 27 - y into equation 1, it becomes
2(27 - y) + 6y = 70
54 - 2y + 6y = 70
- 2y + 6y = 70 - 54
4y = 16
y = 16/4
y = 4
x = 27 - y = 27 - 4
x = 23
Answer:
-4
Step-by-step explanation:
3(5-n)=27
solve
15-3n=27
subtract 15 from 2 sides
-3n=12
n=-4
