If tb=5x and tu=4x-1 and ub=2x-1 what does x equal

Sunny_sXe [5.5K]

If C is a point between AB then we can write AC + CB = AB

Same way we can write tu + ub = tb
tu = 4x - 1 , ub = 2x - 1 and tb = 5x
So we can write it as

$4x - 1+ 2x - 1 = 5x$

$6x - 2 = 5x$

$6x - 5x = 2$

$x = 2$

So x is = 2.

Can u order 4/9 444/1000 .4 from least to greatest

quester [9]

.4 is the smallest since 4/10 is smaller than 4/9 and is only worth 400/1000.

4/9 is a repeater .444.... with the fours continuing forever. If we just go out 3 places from the decimal we get .444 which is 444/1000 and is the second number. Because the 4's continue to go on forever this makes it larger than 444/1000

So the correct order least to greatest is .4 < 444/1000< 4/9

Triangle XYZ with vertices X(0, 0), Y(0, –2), and Z(–2, –2) is rotated to create the image triangle X'(0, 0), Y'(2, 0), and Z'(2

vodka [1.7K]

Answer:

Step-by-step explanation:

Given that there is a triangle XYZ with vertices (0, 0), Y(0, –2), and Z(–2, –2)

This triangle is rotated to form image triangle X'(0, 0), Y'(2, 0), and Z'(2, –2).

We find that origin remains the same.

Hence point of rotation is about the origin

Now (0,-2) is transformed to (2,0)

This is possible if point is rotated about origin anticlockwise a degree of 90

Let us check new coordinate of Z by anticlockwise rotation of 90

We get Z'(2,-2)

Hence the transformation is rotation about origin anticlockwise by degree 90
