The account  A has amount $600 and B has $1600.

<u>Step-by-step explanation:</u>

The given equations are:

a+b=2200 ⇒1

0.03a+0.05b=98  or  \frac{3}{100}a+\frac{5}{100}b⇒2

Change the first equation by isolating a,

a = 2200-b. ⇒3

Apply equation 3 in 2,

\frac{3}{100}(2200-b)+\frac{5}{100}b=98.

66- \frac{3}{100} b+\frac{5}{100}b=98.

66+ \frac{2}{100} b = 98.

6600+2b=9800.

2b=9800-6600.

2b=3200.

b=1600.

Substitute b value in equation 3

a=2200-1600.

a=600.

If possible step by step explanation. thank you!
elixir [45]

Answer:

A

Step-by-step explanation:

\frac{(3x^{2} )^\frac{1}{2} }{3^\frac{1}{2} } =3

(3x^2)^\frac{1}{2} = 3^\frac{1}{2} x

Remember that \frac{x^b}{x^c} =x^(b-c)

Using that \frac{3^\frac{1}{2}x }{3^\frac{1}{2} }=3^(1/2x-1/2)=3^((x-1)/2)

3^\frac{x-1}{2} =3^1

So we can say: \frac{x-1}{2} =1, because the bases are the same

We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.
