(Scroll to the bottom to see my answer) The order of operations is PEMDAS aka Parentheses. Exponents. Multiplication or Division (Which ever come first). Addition or Subtraction (again whichever comes first). Start with (12-9)=3 then multiply 3 by 3, three times=9 then multiply 2 and 7 together=14 then do 9-14=-5

So my final answer is -5! I might be wrong but I did my best! I hope I’m not too late!

grandpa has some cows and ducks in his farm. all in all there are 8 heads and 26 legs, how many cows and ducks are in there? sol
butalik [34]

Answer:

5 cows  and 3 ducks

okay well there are 8 heads and each animal has a head meaning that there are a total of 8 organisms in total. Cows have 4 legs and ducks have 2. Lets say that c is cows and d is ducks. You would have the equations ...

c+d=8

4c+2d=26  

well d techniacally = 8-c, so plug in (8-c) for the value of d

4c+2(8-c)=26.      Distribute to get

4c+16-2c

and then add like terms. Soy ou would get

2c+16=26.

then just isolate the variable but subtracting 16 from both sides and dividing 2 on both sides. The answer you would get is that c=5 so there are 5 cows. Plug in 5 for c so you get 5+d=8 and tadaaaa you subtract 5 from both sides to get that there are 3 ducks.

hope this helps :)

There were 20 dogs and 30 cats at an animal shelter last month. Since then, the number of dogs in the shelter
Softa [21]

Answer:

There is a 4% decrease

Step-by-Step:

if the previous total was 50, then each animal represents 2%. 50*2=100. if you are increasing the dogs by 20% of 20, then you are increasing them by 4 equaling out to 24 dogs. If your decreasing the cats by 20% of 30, then you are decreasing them by 6 equaling out to 24 cats. The new total of animals is now 48. Seeing how each animal still represent 2%, the new percentage is 96%. Subtracting the previous percentage from the new percentage gives a 4% difference.

50 * 2 = 100%

20 * 1.2 = 24

20 * .8 = 24

24 + 24 = 48

48 * 2 = 96%

100% - 96% = 4%
