hammer [34]

Answer:

Kimmy balance in December will be $545.21.

Step-by-step explanation:

Given:

Balance in account in June = $76.23

Now Given, by September her balance is 5 time as much as her June

It means that Balance in account till September is 5 times Balance in account in June.

framing in equation form we get;

Balance in account till September = 5\times \$76.23 = \$381.15

Also Given:

Balance Deposited in account between September and December = $87.83

Now We need to find balance till December.

Kimmy balance till December will equal to sum of Balance in account in June and Balance in account till September and Balance Deposited in account between September and December.

framing in equation form we get;

Kimmy balance till December = \$76.23+ \$381.15+\$87.83 = \$545.21

Hence Kimmy balance in December will be $545.21.

aliya0001 [1]

Answer:

x\geq 29,000 and x\leq 41,000

Step-by-step explanation:

Let x be the altitude of a commercial aircraft

=>The expression " A minimum altitude of 29,000 feet" is equal to

x\geq 29,000

All real numbers greater than or equal to 29,000 ft

=>The expression " A maximum altitude of 41,000 feet" is equal to x\leq 41,000

All real numbers less than or equal to 41,000 ft

therefore, The compound inequality is equal to

x\geq 29,000 and x\leq 41,000

All real numbers greater than or equal to 29,000 ft and less than or equal to 41,000 ft

The solution is the interval [29,000,41,000]
