Answer:
The smallest integer is -4.
Step-by-step explanation:
Let the smallest integer be x.
Since the integers are all multiples of 4, they are
=> x, x+4, x+8, x+12 and x+16
=> x + x+4 + x+8 + x+12 + x+16 = 20
=> 5x + 40 = 20
Subtract 40 from both sides of the equation
5x +40 - 40 = 20 - 40
5x = -20
Divide both sides by the coefficient of x(which is 5)
x = -4
∴ the smallest integer is -4.

Answer:
The money that Aura has is $17
The money that Brain has is $23
The money that Eric has is $46 .
Step-by-step explanation:
The sum of total money does Aura , Brain , Eric have = $86
The money that Eric has = 2 times money that Brain has
The money that Aura has = $6 less than that Brain has
Let The money that Aura has = $A
Let The money that Brain has = $B
Let The money that Eric has = $E
Now, According to question
∵ Sum of total money does Aura , Brain , Eric have = $86
So, $A + $B + $E = $86
Or, A + B + E = 86 .........1
Again
E = 2 × B ..........2
Again
A = B - 6 ..........3
So, (B - 6) + B + 2 B = 86
Or, (B + B + 2 B) = 86 + 6
Or, 4 B = 92
∴ B =
i.e B = 23
So,The money that Brain has = B = $23
Putting the value of B in eq 2
∵ E = 2 × B
So, E = 2 × 23
Or, E = 46
So,The money that Eric has = E = $46
Putting the value of B in eq 3
∵ A = B - 6
So, A = 23 - 6
Or, A = 17
So,The money that Aura has = A = $17
Hence, The money that Aura has is $17
The money that Brain has is $23
The money that Eric has is $46 . Answer
