3x=78+x-2 is the answer. Good luck on your homework!
You can figure out what four times eight is by adding eight and eight(16) and doubling it (32)
Since there are no numbers, i will assume that the length of recess is 1 minute, or x. if social studies is 4 more than 2 times the length of recess, we can use the equation x*2+4 to solve the problem. the end result will be 6 minutes. Social studies is 6 minutes longer than recess
This is just a basic proportion. 5/8 = x/12. So the 5 foot tall women would have a 7.5 foot shadow.
The transformation negates the y-coordinate, so reflects a point across they x-axis.
