Answer:
n=2
Step-by-step explanation:
4(5n-7)=10+2
1) First, distribute (multiply out 4)
20n-28=10+2
2) Combine like terms (add 10 and 2)
20n-28=12
3) Isolate the variable (Add 28 to 12)
20n=40
4) Isolate the variable (Divide by 20)
n=2
Answer:
The median is 2 
Step-by-step explanation:
All you had to do was line them up from lowest to highest.
I think it would be y=(-9/5)x -1/9
V=(pi)(2r^2)(h)
V=4(pi)(r^2)(h)
V=4(100 aka the old volume)
V=400cm^3
Answer:
DB = 13 cm
Step-by-step explanation:
ΔCAB ≅ ΔDBA by ASA, so CA ≅ DB by CPCTC.
CA = 13 cm, so DB = 13 cm.
