Remember you can do ANYTHING to an equation as long as you do it to both sides

isolate the y and then divide by the coefient
the basic way to simplify it is if you did
ax+by=c
y=\frac{-a}{b}x+ \frac{c}{b}

but memorization is no fun so



4y+2x=18
minus 2x both sides
4y=-2x+18
divide both sides by 4
y= \frac{-1}{2}x+ \frac{9}{2}

Okay. So first you subtract 2x from each side. That will give you 4y= -2x+18 (you want to get y by itself). Then you divide both sides by 4. It should equal> y= 1/2x +9/2

Answer:

133/152

Step-by-step explanation:

The probability of 2 independent events is the product of the individual events.  Independent means the first event has no effect on the probability of the second event.  Since we are replacing the first marble, the first even has no effect on the probability of the second event.  

There are 48 total marbles

Let A = pulling a blue marble

Let B = pulling a red marble

So

P(A) = 14/48

P(B) = 19/48

and

P(A then B) = (14/48)(19/48) = 266/2,304 = 133/1,152

The length of a rectangle is 11 in. longer than its width. the perimeter of the rectangle is 86 in.write and solve an equation t
Tcecarenko [31]
I hope this helps you


width w


length w+11



perimeter =2 (width +length )


86=2 (w+w+11)


43=2w+11


32=2w


w=16

length = w+11=16+11=27

Explain how the number line can
DochEvi [55]

9514 1404 393

Answer:

  points closest to zero will give the least change; those farthest away will give the greatest change. Listing the points in order by distance from 0 will put them in order by amount of change.

Step-by-step explanation:

The amount of change is the absolute value of the number on the number line. That value is the (positive) distance from 0. The numbers will most easily be compared if they are all put on one side of zero. For example, -1.75 and 1.75 are the same distance from zero, as are -3.25 and 3.25.

Listing the points in order by distance from 0 will put them in order by amount of change. In order, least change to greatest change, the numbers are ...

  -1.75, 2.50, -3.25, -3.50, 4.75
