Thank you so much!c:

In other words,  the answer is A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,1,2,3,4,5,6,7,8,9 or any other number that stretches out to infinity 

This can't be determined.....the plane could have been at any height.....we would have to know the descent angle to calculate the answer to this question.......{although 15,000 seems most reasonable }

try using the metric system

Go to "how do i type in fractions?"  at the bottom of the page,  in the right-hand corner

So-so.          

Write as x^2(a-2)+3x-a-1, then it will solve for x.. I don't know if there is better way.

Good day to you all  

Today our questions were enthusiastically answered by sasini, CPhill, Alan, gliul, geno3141 and jillybean.  

A big thankyou to each of you

It is you turn to do some work.

If you are not sure that type in your working and we can discuss it.   

4G-3=3G+7

subtract 3G from both sides

then add 4 to both sides

so how much will the job in part cost

y has to be 0

If numbers multiply together to give 0 then at least one of them HAS to be 0.

Alright let's have a look

A house-painting company charges a $376 base rate plus $12 per hour. Another painting company charges a base rate of $280 plus $15 per hour.

Just say a job took 2 hours today.

the first company would charge    $376+  12*2 = 376+24  =  $400  

the second company would charge  280+   15*2 = 280+30 = $310      (this one is cheaper)

Do you understand so far?

We need to know how many hours would the painters work if the price ended up being the same

I don't know how many hours so I called that H

company one         376+12H     dollars

company two         280+15H      dollars

We need to know when these will be the same.

       376+12H   =280+15H 

subtract 12H from both sides

376 +12H-12H  = 280 +15H-12H

376   = 280 +3H

Take 280 of both sides

376-280=280+3H-280

96 = 3H

3H=96

H= 96/3 = 32 hours

now the first company will charge

376+12H = 376 +12*32 = 376 + 384 = $760

the second company will charge

280+15H = 280+15*32 = 280 + 480 = $760

GOOD they are the same - that proves that the answer is correct  

pls help me

what 2 do next

what is the answer

you do not understand what I have already done? 

or you do not understand what do do next?

i don't understand

1x+z=6

x+z=6

z=6-x

a ferry sets sail from an island located at (4,12) on a map. its destination is ferry landing b at (6,2).how far will the ferry travel if each unit on the grid is 0.5 mile?

Using the distance fromula, we have

D =√[(4 - 6)^2 + (12 - 2)^2] =

√[4 + 100]=

√104=

2√26 units

And since each unit is.5 miles we just need to divide this by 2 to get

√26 miles ≈ 5.099 miles

Can you work out what I have done here?

a) I have plotted the points,

b) drawn in a right angled triangle,

c) found the distance on the short sides using subtraction

d) Found the hypotenuse using Pythagorean theorem

How many units on the graph is it?

Remember each unit represents only half a mile so how many miles will it be?
