Just add 2/5+2/5+2/5.

Add: 2       2        2  ----- numerators
       ---- + ---- + ----- =?                                                     
        5        5       5   ------- denominators

Add your numerators first: 2+2+2=6 

Leave your denominators alone they are all 5 so that's ok.

Your answer will be 6
                              ------
                                 5

Hope I helped:)

Evaluate the given expression if x = 25, y = 10, w = 11, and z = 18.<br><br> (see the image)
hammer [34]

Answer:

D

Step-by-step explanation:

So we have the expression:

(x-y)^2+10wz

And we want to evaluate it when x=25, y=10, w=11, and z=18.

So, substitute these values for the variables:

=(25-10)^2+10(11)(18)

First, subtract within the parentheses:

=(15)^2+10(11)(18)

Square 15:

=225+10(11)(18)

Now, multiply the terms on the right. 10 times 11 is 110:

=225+110(18)

Multiply:

=225+1980

Finally, add:

=2205

So, our answer is D.

And we're done!

1 year = how many seconds? Last question in my h.w and idk how to do it:/
Novay_Z [31]
This should help
60 sec = 1min
60min = 1 hour
24hour = 1day
7 days = 1 week
around 4.3 weeks = 1month
12 months = 1 year

or you could use 365 days and times that by 24 than times that by 60 to get mins and again by 60 to get seconds.

hope this helps
