Mostly collect like terms
use associative property which is
(a+b)+c=a+(b+c)
and remember that:
you just use a general rule
x+x=2x
x^2+x^2=2x^2
3xy4xy=7xy
3x+4x^2=3x+4x^2
you can only add like terms( like terms are terms that are same name like x or y are differnt, and like terms have same power exg x^2 and x^3 and x^1/2 and such


so first one



3b+11c-4c-c
since they are all c except for the first one term, just assign a number for each so it simplifies to c times(11-1)+b(3-4)=c(10-1b=10c-b or

you just use a general rule
x+x=2x
x^2+x^2=2x^2
3xy4xy=7xy
3x+4x^2=3x+4x^2




second one9a-1+8c-8a+c
group like terms
(9a-8a)+(8c+c)-1=(a)+(9c)-1=a+9c-1

12c+5a+7-13c+4a
group like terms(12c-13c)+(5a+4a)+7
add like terms
-c+9a+7
the solution is 9a-c+7


-15-6c+3b-6c+9-2b
group like terms
(-15+9)+(-6c-6c)+(3b-2b)
-6+(-12c)+b=b-6-12c



the answers are:

10c-b

a+9c-1

9a-c+7

b-12c-6

Anna hikes at a constant speed travels 6 miles in two hours find her speed in miles per hour you seen an equation for the distan
harina [27]

Answer:

The speed at which Anna travel with her bike is 3 miles per hour .

Step-by-step explanation:

Given as :

The distance cover by Anna = 6 miles

The time taken by the Anna to cover the distance = 2 hours

Let The speed in miles per hour = s miles per hour

<u>Now, As we know </u>

Speed = \dfrac{\textrm Distance}{\textrm Time}

So, s =  \dfrac{\textrm 6 miles}{\textrm 2 hours}

or, s = 3 miles per hours

So, Speed = 3 mph

Hence The speed at which Anna travel with her bike is 3 miles per hour . Answer

MIDPOINT AND LINE LENGTH<br><br> WILL GIVE 70 MORE IF CORRECT
aleksandrvk [35]

Answer:

so midpoint formula is (x1+x2/2, y1+y2/2)

Step-by-step explanation:

so for 1: (11-11/2, 4+12/2)= (0,8)

then if you have the midpoint and one endpoint, find the distance between them to find the other endpoint.

so, for the third example, start with the x. how fair is -8 from -1? The answer is 7. So, we must ask, what number is 7 more than -1? Answer is 6. Then repeat for the y. 6 is 5 units away from 1, so then we do 1-5=-4. So it should be (6,-4) as point B
