A giant tortoise can walk about 1/10 meters per second on land. A cooter turtle can walk about 1/2 meter per second on land. How

timurjin [86]

(1/10) / 1 = 3 / x.....1/10 m to 1 second = 3 m to x seconds
cross multiply
(1/10)(x) = (3)(1)
1/10x = 3
x = 3 / (1/10)
x = 3 * 10/1
x = 30 seconds <====

A 7000.00 principal is invested in 2 accounts, 1 earning 3%interest the other 7% interest with the total interest for the year 2

MakcuM [25]

Answer:

The amount in the first account is $5,700

The amount in the second account is $1,300

Step-by-step explanation:

Let the mount invested in the first account be $x$ and the one invested in the second account be $y$ .

Then the total principal is $x+y=7000$ ---->(1)

The interest in the first account is $.03*x$

The interest in the first account is $.07*y$

The total interest for the year is 262.00.

This implies that:

$0.03x+0.07y=262$ ---->(2)

We solve the two equations simultaneously to get:

$x=5,700$ and $y=1,300$
