You begin with $25 in a savings account and $50 in your checking account. Each week you deposit $5 into savings and $10 into che
Phantasy [73]

Answer:

The amount in checking will always be twice in any week.

Step-by-step explanation:

Let's say, w represents the week, s represents the saving account and c represents the checking account.

Balance in saving account in any week =s=5w+25

Balance in checking account in any week  =c=10w+50

Translate the statement into mathematical equation. Remember to use " = " for word "is" in the given statement.

We have to find w for 2s = c.

Putting the values, we have:

2(5w+25)=10w+50

\Rightarrow \mathrm{True\:for\:all}\:w

Which means in each week the amount in checking is twice the amount in savings.

Best Regards!

erik drove 439.92 miles on 15.6 gallons of gas. To the nearest hundredth, how many miles could he drive on 39.7 gallons of gas?
Thepotemich [5.8K]
In the question it is already given that Eric drove for 439.92 miles on 15.6 gallons. It is required to find the distance traveled on 39.7 gallons of gas. Also we have to find the answer to the nearest hundredth.
Then,
In 15.6 gallons Eric can drive for a distance = 439.92 miles
In 39.7 gallons Eric can drive for a distance = [(439.92/15.6) * 39.7] miles
                                                                       = 1119.54 miles
So the total distance traveled by Eric is 1120 miles with 39.7 gallons of gas. The answer has been calculated to the nearest hundredth.
