"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 $\dfrac{750}{2}=\$375$

Evaluate each expression for s=4 and t=8 1) (25)^2t 2) 2st^2-5^2 3) 2s^2-t^3/16

stepladder [879]

Answer:

1. 2.328× $10^{22}$

2. 487

3. 30.52 OR 0 (see explanation↓)

Step-by-step explanation:

1. $(25)^{2t}$

(sub for t=8)

= $25^{2*8}$

= $25^{16}$

=2.328× $10^{22}$

2. $2st^{2} -5^{2}$

(sub for s=4 and t=8)

=2×4× $8^{2}$ - $5^{2}$

=512-25

=487

3. $2s^{2} -t^{3/16}$ (the equation is not clear so I will do $2s^{2} -\frac{t^{3} }{16}$ as well)

FOR $2s^{2} -t^{3/16}$

(sub s=4 and t=8)

=2× $4^{2}$ - $8^{3/16}$

=32-1.476826146

=30.52 (to the nearest 2 decimal place)

FOR $2s^{2} -\frac{t^{3} }{16}$

(sub s=4 and t=8)

=2× $4^{2}$ - $\frac{8^{3} }{16}$

=32-32
