Answer:
x = 10
Step-by-step explanation:
Adjacent angles add to 180 degrees, so set the angles equal to 180
(7x + 12) + (9x + 8) = 180
- 12 - 12
7x + (9x + 8) = 168
- 8 - 8
7x + 9x = 160
16x = 160
/16 /16
x = 10
I think you may need a picture; nobody can help if we don’t know the size of the different sizes of the packages (:
Answer:

Answer:
x= 34 not 4
Step-by-step explanation:
The error is in the second and third lines: instead of dividing 8 by 4, it's should have been 8×4
And then you will get the following equation:
x-2= 32
x=32+2=34
Answer:
Point D is plotted incorrectly.
Step-by-step explanation:
The points are given to be :
Now, Points on a number line are plotted in the increasing order or ascending order. because the number line moves from left to right.
So, to check the point which is plotted incorrectly, arrange the given points in increasing order :
So, the point D is plotted incorrectly. It would have been plotted after point A in order to plot the points correctly on the number line.
Hence, Point D is plotted incorrectly.
