Answer:
M = n - 1
Step-by-step explanation:
7m + 2 = 7n - 5
Group like terms
7m = 7n - 5 - 2
7m = 7n - 7
7m/7 = 7n /7 - 7/7
M = n - 1
180+x=7x because the father plus the daughter is equal to 7 times her weight which is x?
Answer:
6 ft above ground.
Step-by-step explanation:
The roller coaster starts from an elevation of +20 feet from the ground.
Now, it first corns 78 ft, then drops 85 ft.
So, the final elevation will be (20 + 78 - 85) = 13 feet above the ground on the second hill.
Again, it climbs 103 ft. and drops 110 ft. and finally his elevation will be = 13 + 103 - 110 = 6 ft above ground. (Answer)

Answer:
45
Step-by-step explanation:
The n th term of a GP is
= a
where a is the first term and r the common ratio
Given a₂ = 6 and a₅ = 48, then
ar = 6 → (1)
a
= 48 → (2)
Divide (2) by (1)
= 
, that is
r³ = 8 ( take the cube root of both sides )
r = ![\sqrt[3]{8}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D)
= 2
Substitute r = 2 into (1)
2a = 6 ( divide both sides by 2 )
a = 3
Thus
3, 6, 12, 24 ← are the first 4 terms
3 + 6 + 12 + 24 = 45 ← sum of first 4 terms
