6.5 weeks.

55+50=105

35+60=95

It gets too wide when we double again.

55+ 100 =155

35+150=185

Therefore 55+70 =125

35+105= 125 Still too wide.

55+60=115

35+90= 125

The answer is between 6+ 7 weeks.

We then look at days.

Divide 55 weeks into 6.5 weeks less one day. Then apply 6.5

8.5 x 6.5 = 55 but when we plus 8.5+6.5=15

Divide 35 weeks into 6.5 weeks no remainder

5.5 x 6.5 = 35.75 =12

We see the ratio is 4:5

Banks round down and up for .5 answers.

Therefore both decimals round up so the answer is 6.5 weeks.

Answer from: mirzakasumovic8926

it will take 4 months for the amount to be the same and the amount would be $95

Step-by-step explanation:

Let x represent the number if months it will take for the two accounts have the same amount of money.

Christiana opened her account with $55 and plans to deposit $10 every month. This means that the amount that in the account after x months would be

10x + 55

Marlena opened her account with $35 and plans to deposit $15 every month. This means that the amount that in the account after x months would be

15x + 35

For the amount in the accounts to be the same, the number of months would be

15x + 35 = 10x + 55

15x - 10x = 55 - 35

5x = 20

x = 20/5

x = 4

The amount would be

15 × 4 + 35

= 60 + 35

= $95

Answer from: Quest

the simplified form is

$\frac{x^2(2x+3)}{2(4x-3)}$

step-by-step explanation:

we want to simplify the expression,

$\frac{\frac{6x+9}{15x^2} }{\frac{16x-12}{10x^4} }$

let us change the middle bar to a normal division sign to obtain,

$\frac{6x+9}{15x^2}\div\frac{16x-12}{10x^4}$

we multiply the first fraction by the reciprocal of the second fraction to obtain,

$\frac{6x+9}{15x^2}\times \frac{10x^4}{16x-12}$

we factor to obtain,

$\frac{3(2x+3)}{3\times5\times x^2}\times \frac{2\times5\times x^2\times x^2}{4(4x-3)}$

we cancel the common factors to get,

$\frac{(2x+3)}{1}\times \frac{ x^2}{2(4x-3)}$

we simplify to get,

$\frac{x^2(2x+3)}{2(4x-3)}$

the correct answer is b
