Step-by-step explanation:
Scale Factor of UVW to XYZ
= XY/UV = YZ/VW = XZ/UW
= 21/3 = 28/4 = 14/2
= 7. (B)
If o<span>n a coordinate grid, Ming's house is located 2 blocks to the right and (I suppose also 2) blocks up from (0. 0), then the ordered pair that describes the location of Ming's house is (2,2) (moving right 2 units from some point you have to add 2 units to the x-coordinate of the point from which you are moving and moving up 2 units from this point you have to add 2 units to y-coordinate of the point from which you are moving up).

If Joe's house is located 3 blocks to the right and 2 blocks down from Ming's house, then the ordered pair that describes the location of Ming's house is (2+3,2-2), that is (5,0) <span><span>(moving right 3 units from some point you have to add 3 units to
the x-coordinate of the point from which you are moving and moving down 2 units
from the point you have to substract 2 units from y-coordinate of the point from which you are moving down)</span>.</span>
69, 70, 71, and 72
69 and 71 are the first and third digits. 69+71=140
First we have to distribute the parentheses on the left side, 2*x is 2x and 2*-3 is -6, so now the equation is 4x+2x-6 = 8x+12
Then, we can add together the two x's on the left side,
so now we have 6x-6 = 8x+12 Subtract 12 from both sides and
you get 6x -18 = 8x Then you can subtract 6x from both the sides and get
-18 = 2x Now we can divide both sides by 2, and the final answer is -9 = x
Since they are not the same and the two sides aren't unequal, there is one solution(:
Hope this is helping you(:
