Answer:
2286
Step-by-step explanation:
If p represents the towns population, you have ...
14% × p = 320 . . . . . 14% of the population is 320 people
p = 320/0.14 ≈ 2286 . . . . divide by the coefficient of p
The town's population is approximately 2286 people.
X= smaller number
y= larger number
We will have two equations to work with so we can solve for the variables.
EQUATION 1:
3 * y= 4 * x
3y= 4x
subtract both sides by 3y
0= 4x - 3y
EQUATION 2:
21= x + y
SOLVE:
solve for one variable in equation 2
21= x + y
subtract both sides by y
21-y= x
Substitute x= 21-y in equation 1:
0= 4x - 3y
0= 4(21-y) - 3y
0= (4*21) + (4*-y) - 3y
0= 84 - 4y - 3y
0= 84 - 7y
add 7y to both sides
7y= 84
divide both sides by 7
y= 12
Substitute y=12 in either equation to solve for x:
21= x + y
21= x + 12
subtract both sides by 12
9= x
CHECK:
0= 4x - 3y
0= 4(9) - 3(12)
0= 36 - 36
0= 0
ANSWER: x=9 and y=12
Hope this helps! :)
