Answer: 19 birds were at the shelter on Wednesday.
Step-by-step explanation:
Let x represent the number of birds that were at the shelter on Wednesday.
Let y represent the number of birds that were at the shelter on Wednesday.
Nicole found a record showing that there were a total of 40 birds and cats on Wednesday. This means that
x + y = 40
The animal shelter spends $5.50 per day to care for each bird and $8.50 per day to care for each cat. Nicole noticed that the shelter spent $283.00 caring for birds and cats on Wednesday. This means that
5.5x + 8.5y = 283 - - - - - - - - - - - - - -1
Substituting x = 40 - y into equation 1, it becomes
5.5(40 - y) + 8.5y = 283
220 - 5.5y + 8.5y = 283
- 5.5y + 8.5y = 283 - 220
3y = 63
y = 63/3 = 21
x = 40 - y = 40 - 21
x = 19
Answer:
16
Step-by-step explanation:
6+8+10+20=44+16= 60 divided by 5 is 12
<span>The interior angles of any polygon always add up to a constant value, which depends only on the number of sides. We use the equation as follows:
</span>sum = 180 (n−2) degrees
sum = 180 (29 - 2) degrees
sum = 4860 degrees
Hope this answers the question. Have a nice day.
