Which expression is the result??

1 answer:

To answer this, you will use inverse operations to rewrite the equation in terms of x.

First add b to both sides. This eliminates the b on the let and adds b to the right expression.

Then, divide both sides by a to undo the multiplication by a on the left. You will be left with the x alone and you will have (cy + b)/a as your answer. This is the first choice on the left.

A rectangle's width is twice as long as its length. If the perimeter is 36 in., what is the length?

Bumek [7]

Okay here:

Let L be the length and W the width of the rectangle.

1. w=2•L
2. 2L+2W=36

Substitute eq. 1 into eq. 2,

2L+2•(2•L)=36

2L+4L=36

6L=36

L=9

Not done yet, then from eq. 1,

W=2•L
W=2•9
W=18 <------- Your answer. :)

2x-y=-2 -x-2y=4 estimate the coordinates

ValentinkaMS [17]

You can subtract the 2x to make it -y=-2x-2 and add the x to make it -2y=x+4. for elimination method multiply the equation (-2)-y=-2x-2. Hope this helps. You can also do substitution method
