To get the answer we have to use proportion
36% ------------------72
100% ----------------x
Crossmultiply now
100*72=36*x
7200=36x /:36 divide both sides by 36
7200:36=x
200=x - its the answer
8C3=8*7*6/3*2*1=8*7=56
5C2=5*4/2*1=10

Step-by-step explanation:
You will divide 16 into 6,832 then you will do 16 times 4 and it will give you 64 and you subtract that and you will get 43 and then do 16 times 2 and you will get 32 and you subtract 43 and 32 then you will multiply 16 times seven and you will get 112 and subtract that by 112 and you will get zero.
Answer:
1. 3x-7y and -7y+3x
Step-by-step explanation:
1. 3x -7y and -7y +3x
This is correct because the terms remain unchanged. The -7y stays a -7y and the positive 3x stays a positive 3x.
2. 3x -7y and 7y -3x
This is not correct because the signs of the 3x and 7y switch. For the expressions to be equivalent, the signs must remain unchanged.
3. 3x -7y and 3y -7x
This is not correct because the variables of the 3 and 7 switched. The variables need to stay the same, for the expressions to be equivalent.
4. 3x-7 and -3y+7x
This is not correct because both the variables and the signs of the expressions changed. Both the signs and variables would need to stay the same in order to be equivalent.
