Answer:
108 people
Step-by-step explanation:
4 : 5
To go from 4 to 48 we times by 12. So we do the same to 5.
5 times 12 = 60
48 + 60 = 108
:)
Well this is a hard question to answer, but this is how i would put it.
You would take a number (lets use 15) and the second number (lets use 5) would determine how many times it would go into 15. In other words, 5 time x would equal 15 (5x=15). 5, being a factor of 15, would evenly fit into 15 three times.
Answer:
The answer is 17.

Answer:
E = 427 votes
Step-by-step explanation:
- Let Elaine's vote be E
- Let Dean's vote be D
- Let Clara's vote be C.
Translating the word problem into an algebraic expression, we have;
E = D + 95
E = C + 186
Equating the two equations, we have;
D + 95 = C + 186
D = C + 186 - 95
D = C + 91
Also, the sum of all the votes is equal to 1000.
E + D + C = 1000
Substituting the value of "D" we have;
E + (C + 91) + C = 1000
E + C + 91 + C = 1000
E + 2C + 91 = 1000
E + 2C = 1000 - 91
E + 2C = 909
But, E = C + 186
Substituting the value of "E" we have;
(C + 186) + 2C = 909
C + 186 + 2C = 909
3C + 186 = 909
3C = 909 - 186
3C = 723
C = 723/3
<em>C = 241 votes</em>
Next, we would find Elaine's vote;
E = C + 186
E = 241 + 186
<em>E = 427 votes</em>
Lastly, we would find Dean's vote;
E = D + 95
427 = D + 95
D = 427 - 95
<em>D = 332 votes</em>
<u>Check:</u>
E + D + C = 1000
427 + 332 + 241 = 1000
1000 = 1000
