Answer:D
Step-by-step explanation:
The total number of persons standing in the line waiting for ordering pizza are 5.
Explanation:
There are 5 people in total so the first place can be occupied by any of the 5 persons.
Secondly the second place in the line can be occupied by any of the 4 persons left.
Then the third place will be occupied by any remaining 3 persons as the front two places are already occupied.
Similarly the fourth place will be taken by any of the remaining two people. And lastly the last place will b filled by the last remaining person.
So the total number of ways will be 5*4*3*2*1 = 120 ways that is given in the question.
Answer:
1. 40 members
2. 4 cheerleaders
3. 40 marbles
4. 2 marbles
5. 8
6. 24
Step-by-step explanation:
1. cross multiply 12/x=30/100
2. cross multiply 12/x=10/100
3. 18/x=45/100
4. x/40=5/100
5. we know 5% is 2 marbles. multiply by 4 to get 8 marbles.
6. 20%=8 marbles. 60/20= 3. 3 x 8= 24 marbles.
1) 8x-13
2)19r-19s
3)8m-10n
Solve in the parentheses then label the ones with the same variable and solve those setting up the equation with variable first. Do check this I am not perfect.
Hope this helped! ;)
