What is 5w + 8 - 12w = 16 - 15w

I suppose you are asking what "w" is:
your equation is
5w+8-12w=16-15w
combine like terms to get
-7w+8=16-15w
add 15w on both sides(since you're doing it to both sides the equation is still equal)
8w+8=16
subtract 8 from both sides
8w=8
divide both sides by 8 and you get:
w=1
if you want to check your answer, plug in the value of "w" into the original equation.

What is the nth term of 0 3 8 15 24 35 48
Natasha2012 [34]
So 3+5=8
8+7=15
15+9=24
24+11=35
35+13=48
therefore
0+3=3
so therefore the answer this is a difficult question but the answer is kind of like whatever you added to n in the last term add two to that and add to your number to get that

Your plan was to be on the road by 9 A.M. but you did not leave the garage until 10 A.M. You then drove with the cruise control
Wittaler [7]

Answer:

The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.

Step-by-step explanation:

The average speed is given by the following equation:

v = \frac{d}{t}

From 10A.M. to noon.

You traveled at 50mph during 2 hours. So how long you traveled?

50 = \frac{d}{2}

d = 50*2

d = 100

You traveled 100 miles.

What was your average speed over the time interval from 9 A.M. to noon

From 9 A.M. to 10 A.M, you did not travel.

From 10 P.M. to noon, 100 miles.

So 100 miles during 3 hours.

v = \frac{d}{t} = \frac{100}{3} = 33.33

The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.
