Answer:
5
Step-by-step explanation:
Assuming both players can answer the same question, the minimum number of questions is the smallest number that when multiplied by either 0.60 or 0.80 yields a whole number.
Let x be the number of questions, solving by trial and error:
Therefore, the minimum number of questions in the game is 5.
D, one number is positive and the other is negative. The only way it could equal 0 is to cross the other out. An example is, -5+5=0
Answer:
60:150
Step-by-step explanation:
So first you can divide 210 by 7 since it will be spilt into seven parts.
210/7 = 30
So in order to get them into the ratios:
30 x 2 = 60
30 x 5 = 150
So 210 in the ratio of 2:5 would be 60:150
You can check your work by adding 60 + 150 together.
Answer:
Step-by-step explanation:
Given inequality:
Eliminate the denominator of the fraction by multiplying both sides by -24, remembering to flip the relation (inequality symbol) as the factor is <u>negative</u>.
Therefore, the solution is 
Factor dem groups
find greatest common factor
24=2*2*2*3
40=2*2*2*5
common is 2*2*2=8
answer is 8 groups
