Answer:

The distance traveled by the B737-400 aircraft in 5 hours is 2,000 miles

Step-by-step explanation:

Average speed = 400 miles per hour

Distance = 400t

t= 5

Total distance = 400t at t hours

Total distance when t = 5 hours

Total distance traveled = 400t

= 400 × 5

= 2,000 miles

Total distance travelled = 2,000 miles

The distance traveled by the B737-400 aircraft in 5 hours is 2,000 miles

hope this helps

The pool at "Splash Around" is open for 14 weeks during the summer. You can swim for $6 a session, or you can buy a membership f
iris [78.8K]
Price before membership= price 1 = $6
price after membership = price 2 = $4
Membership price = $100
SO according to price 1 and price 2; price after membership saves up $2 for each session.
Hence to justify the price of membership number of sessions can be calculated as follows:-
$2 saved = 1 session
to make it $100 multiply both sides by 50
2×50 = 1×50
100$ saved = 50 sessions
so 50 sessions ate required to justify buying the membership.


Hope this helped :)

svetoff [14.1K]

Answer:

x=2; y=-1

Step-by-step explanation:

Hello,

(1) 6x+7y=5

(2) 2x-3y=7

We multiply equation (2) by 3, it gives

6x-9y=21 and we subtract from (1)

6x-9y-6x-7y=-16y=21-5=16

So y = -1

we replace in (1) 6x-7=5 <=> 6x=7+5=12 <=> x =12/6=2

thanks
