To solve both of these expressions, we want to add or subtract from left to right.

For the first one, we can rewrite it as:

8-6-9
=2-9
=-7

The second one we can rewrite as:

5-7+9+8-4
=-2+9+8-4
=7+8-4
=15-4
=11

The annount of time (in minutes) that it takes to put out a fire varies inversely
sveticcg [70]

Given that the amount of time varies inversely with G.

It can be written as,

T G=K

where K is the constant.

We need to determine the time it takes to put out the fire when 200 gallons of water are used.

<u>The value of constant:</u>

When G=8, T=12 , we get;

(12)(8)=K

      96=K

Thus, the value of constant is  96.

<u>Time taken:</u>

Substituting G=2 and K=96 in the formula T G=K, we get;

T(2)=96

    T=48

Thus, the time taken to put out the fire using 200 gallons of water is 48 minutes.

Hence, Option B is the correct answer.

vodka [1.7K]
From information given, we know
208 miles was at rate of 65 mph. so divide total mileage by speed to get time spent.

208 ÷ 65 = 3.2 hours

So the rest of the trip took 6 - 3.2 = 2.8hours to travel another 348 total miles minus the 208 miles driven at 65mph is 140 miles.

140 miles divided by 2.8 hours gives speed

140 ÷ 2.8 = 50 miles per hour
