If you divide 4.16 by 5.20 you get .8 which would be .80 cents a pound
Mean = (1+1+2+3+3+3+4+5)/8 = 22/8 = 2.75
answer
mean = 2.75
The way your problem is set it should be simplified to this....4x + 55
V=B+15
V+2B=180
Therefore:
3B+15=180
B=55
V=70
Check:
V+2B=180
70+2(55)=180
70+110=180
180=180. Checks.
Answer:
3(x-2)(x+5)
Step-by-step explanation:
1. Factor out common term 3
