Answer:
Nephew receive 1500.00
Older niece receive 1000.00
Younger niece receive 500.00
Step-by-step explanation:
Let assume a variable x,y,z for the niece, older niece and the nephew respectively.
Y= 2x (Twice the younger niece)
Z= x + y. (Sum of the two nieces)
Since y = 2x
Z = x+2x
Z= 3x
Therefore:
X = 1x
Y = 2x
Z = 3x
So the will will be shared among them in the ratio
Nephew : older niece : younger niece
3 : 2 : 1
Nephew. 3/6 x 3000 = 1500.00
Older niece 2/6 x 3000 = 1000.00
Younger niece 1/6 x 3000 = 500.00
12q +3r =15
3(4q +r) = 3*5
Divide both sides by 3
4q +r = 5
Time for the second one:
-4q -4r = -44
-4(q +r) = (-4)*11
Divide both sides by -4
q +r = 11
4q +r = 5
q +r = 11
Subtract the second from first equation
3q 0 = -6
3q = -6
q = -6/3 = -2
q = -2
q +r = 11
-2 +r =11
r = 11 +2
r = 13
q = -2
r = 13
Your answer is...
(-2,13)
