Answer:
(3).
women having 3 or more than cups of coffee per day in comparison to those having 1 or fewer than one has 33% lower odd of memory loss and 18 % lower odd of visual and spatial memory decline.Age is also the factor that determines the extent of Benefit as women over 80 repeaing has more benefits than women 10 to 15 year younger.
(5).
Reading the above article I came to acknowledge that the are women only benefited because they don't metabolizes coffee in a same way as men do. so men should take more care of their coffee consumption than women.
(6).
lifestyle choices may protect one with mild form of age related memory loss from future decline. Essentially what is healthy for body is healthy for brain.

I used a site called tiger algebra to solve this so I don't know how, but I hope this helped you anyway. :)
Answer:
7 people purchase the items and they used 53 coins
Step-by-step explanation:
Let x represent the number of people.
Let y be the number of coins needed to purchase the items.
If each person pays 8 coins, the surplus is 3 coins. This is illustrated below:
8x = y + 3 (1)
if each person gives 7 coins, the deficiency is 4 coins. This is illustrated below:
7x = y — 4 (2)
Solving by elimination method: subtract equation(2) from equation (1). This is illustrated below:
8x = y + 3 (1)
— (7x = y — 4) (2)
x = 7.
Next, Substituting the value of x into any of the equation to obtain y. In this case I will be using equation 1 as illustrated below:
8x = y + 3 (1)
8(7) = y + 3
56 = y + 3
Collect like terms
y = 56 — 3
y = 53
Therefore, 7 people purchase the items and they used 53 coins
(w - 7)(w + 4)
w^2 - 7w + 4w - 28
w^2 - 3w - 28
Answer:(first term)
a=27(4th term)
T4= a x r^3 = 64
substituting a as 27 in T4
27 x r^3 = 64
r^3 = 64/27
r=4/3
so; a=27, r=4/3
using the general formula of geometric progression,
a x r^n-1
substitute:.
27 x 4/3^n-1
= 27(4/3)^n-1
