Assume the number is x
now, we will translate the written english into equation:
seven minus 2 times the number is 7-2x
the number minus 2 is x-2
we will equate these two equations (the question says that they are equal) ans solve for x as follows:
7-2x=x-2
7+2=x+2x
9=3x
x=3
the required number is 3
Answer:
B. 120 units³
Step-by-step explanation:
The area of the large white rectangle on the right represents the area of one of the larger surfaces of the prism. It appears to be (10 units) × (6 units), so has an area of 60 units². (You can count the squares there, if you like.)
That is adjacent to a gray area on the net that is 2 units wide, indicating that the prism is 2 units deep. Thus the volume is ...
(60 units²) × (2 units) = 120 units³
Which expression is equivalent to 1/2 (2+ 3x – 6)?
3x - 5
3/2x - 5
3x – 4
3/2x - 2
The Answer Is B
