Answer:

LCM(9, -1, -1, +2, +2, +2) = 2×3^2 = 18

Step-by-step explanation:

9 = 32

-1 = -1

+2 = 2

LCM = 2×3^2 = 18

18 / 9 = 2

18 / -1 = -18

18 / +2 = 9

"Bert has half as much money as Ernie. If Ernie loses $225 and Bert earns $675, Bert will have twice as much money as Ernie. How

Rzqust [24]

Answer: Ernie has $750 and Bert has $\dfrac{750}{2}=\$375$

Step-by-step explanation:

Let the amount that Ernie has be 'x'.

Let the amount that Bert has be $\dfrac{x}{2}$

Amount lost by Ernie = $225

Amount gained by Bert = $675

According to question, we get that

$2(x-225)=\dfrac{x}{2}+675\\\\2x-450=\dfrac{x}{2}+675\\\\2x-\dfrac{x}{2}=675+450\\\\\dfrac{4x-x}{2}=1125\\\\\dfrac{3x}{2}=1125\\\\x=\dfrac{1125\times 2}{3}\\\\x=\$750$

Hence, Ernie has $750 and Bert has $\dfrac{750}{2}=\$375$
