Answer:
36 teachers
Step-by-step explanation:
total students=128+121+135=384
groups of 32=384/8=12
teachers=12x3=36
The answer should be Step 1; 3(1+2x)-2(x+1)+5
D. 1mm/10cm is the correct answer choice.
The answer is n=28;
1. Subtract 14 from both sides (-n/2 = -14)
2. Multiply by 2 on both sides to get rid of the fraction (-n = -28)
3. Divide by -1 to get n by itself (n = 28)
You could also eliminate step three by multiplying by -2 instead of just 2.
