We would plug in x to all of those equations. So, 3(4+4)(4+1)/(4+2)(4-2). This would be 3(8)(5)/(6)(2). Then multiply them. 3(8)(5) would be 120. (6)(2) would be 12. Then divide 120 and 12 to get 10.
Answer:
Real distance between Manchester and London = 263.2 km
Step-by-step explanation:
Given that:
A map has a scale of 1 cm = 14 km
Ratio = 1 : 14
Distance from Manchester to London = 18.8 cm
Let,
x be the real distance between Manchester and London.
Ratio = 18.8 : x
As the relationship is proportional,
1 : 14 :: 18.8 : x
Product of mean = Product of extreme
14*18.8 = x
x = 263.2 kilometers
Hence,
Real distance between Manchester and London = 263.2 km
Answer:
Step-by-step explanation:
now i dont know if you know how to do this or anything but i will tell you a way to that you will always remember how to do it the mean is where you have to add evrything up and divide it by the amount of numbers always said its mean that they make you add up all the numbers and have to divide it and your meanis messed up it is actually 291
Answer:
The 12th term in the sequence is b(12)= -26
Step-by-step explanation:
For the 12th term, that means we need to find what the value of b is when n=12
To find b:
- Substitute all 'n' with 12 (since its the 12th term)
b(n)= -4-2(n-1)
b(12)= -4-2(12-1)
- Solve the equation in order of BEDMAS (aka PEDMAS)
b(12)= -4-2(11)
= -4- (2*11)
= -4-(22)
= -26
The 12th term in the sequence is b(12)= -26
3 1/2 x 1 1/2 x 2 = 2/2 ( in simplest form) not simplified is 7/2, as a decimal is 10.5, and as a mixed number is 10 1/2 hope it helps!
