Answer:
x=-1
Step-by-step explanation:
2x - 3 = -4x - 9
Add 3 and 4x on both sides.
2x + 4x = -9+3
Add or subtract like terms.
6x = -6
Divide 6 into both sides.
6x/6=-6/6
x=-1
The solution to this equation is x=-1.

Answer:
12
Step-by-step explanation:
If there are 3 classrooms that each have 25 desks and there are a total of 87 students, how many more desks need to be added to a 4th classroom, that was originally empty, so that each of the students has a desk to sit in?
25 * 3 = 75
87 - 75 = 12
I think the only way to properly create a back to back stem plot here is to convert meters to feet or feet to meters. The conversion is 1 ft = 12 in = 30.48 cm = .3048 meters. Since this is a guesstimate, you could also say that a foot is about 1/3 of a meter, and divide all feet values by 3. Then create a back to back with the new values, rounded to nearest whole number. Hope this helps
