Answer: there were 19 birds at the shelter on Wednesday
Step-by-step explanation:
Let x represent number of beds at the shelter on Wednesday.
Let y represent the number of cats 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
x = 40 - 21 = 19
The answer would be 4(x+1).
Well you need to convert the percentage into a decimal . E.g: if the tax was 7% it would be 0.7 in decimal form. Then , you need to multiply your decimal by the priced the product. Whatever that number is, is your tax. Add your tax to the price of the product and you have successfully found your whole price.
The next three terms are 2, 1/2, 1/4
You take 1/2 of each previous term to get the next term, which means this sequence is geometric (first term is 4, common ratio is 1/2)
So for the first one you would replace Y with what it = which in this case is -x+7So it would look something like this
-x+7=-x+7
