Answer:

x=0

Step-by-step explanation:

2(x-3)+9=3(x+1)+x

2x-6+9=3x+1+x    You first distribute on both sides

2x+3=4x+1           Then you add

2=2x                     Subtract

X=0                      Then you're done!

The amount of oil used by a ship traveling at a uniform speed varies jointly with the distance and the square of the speed. The
frosja888 [35]

Answer:

Step-by-step explanation:

Joint variation has the equation

y = kxz

k is the constant of variation and needs to be solved for using the initial conditions, then filled in later to another equation related to the given info to solve for something else.  We are given y = amount of oil used, x = distance traveled, z-squared is the speed.  Our equation looks like this, to be exact:

y=kxz^2

Filling in with the initial conditions:

34=k(60)(20)^2 which gives us the

k = .0014166667

Now we need to find the amount of oil used, y, under other circumstances, but this time we have our k.

y=(.0014166667)(32)(23)^2

which gives us that the amount of oil used, when rounded to the tenths,

y = 24.0 barrels

Answer:

Step-by-step explanation:

-2x + 3 = 0

-2x = -3

x = 3/2

-x^2 + 2x + 3 = (-3/2)^2 + 2 × 3/2 + 3

= 9/4 + 3 + 3

= 9/4 + 6

= 33/4

The temperature in the late afternoon
Fantom [35]

Answer:

-7.5 - (8.5 + 5)

Step-by-step explanation:

We just add together the values of how much it dropped at different parts of the day, and subtract them from what we started with. The parenthesis are important cause we want to know what the total temperature drop for the day was before we subtract it to get the actual temperature we end up with.
