Answer:

Step-by-step explanation:

The length can be found by setting up a proportion. If the width is reduced by some ratio, then the length will share the same ratio.

3 / 8 = x / 10 Multiply both sides by 10.

3 * 10 / 8 = x Multiply first

30/8 = x Divide next. You don't need to do it in this order.

3 6/8 Simplify

3 3/4 Give another choice

3.75

The length = 3.75 inches

If none of these are correct, please leave a note with your choices.

Anton [14]

Answer:

$y=450+70x$

Step-by-step explanation:

Let the number of months = x

It is given that,

Carson deposits $70 each month and has $450 in his bank account.

So, the initial deposit is $450 and monthly deposit is 40x.

Let Carson's bank balance = y (in dollars).

Thus, the linear function representing the bank balance is,

$y=450+70x$
