Answer:
ok
Step-by-step explanation:
26 to nearest year
We require the total of the sums of ages for both groups before calculating the mean for all 16
using mean = 
Women
27 = 
( cross- multiply )
sum = 9 × 27 = 243
Men
25 = 
( cross- multiply )
sum = 7 × 25 = 175
Total sum of all 16 = 243 + 175 = 418
mean = 
= 26 ( to nearest year )
This is not the answer but i love ur pfp
I will explain step by step how to solve for x
Remove the parenthesis using distributive property
1.5(x + 4) - 3 = 4.5(x - 2)
1.5(x) + 1.5(4) = 4.5(x) - 4.5(2)
1.5x + 6 = 4.5x - 9
Combining like-terms. Move the terms whose variable x to the left side, and move constants to the right side. Plus sign will become substract sign after being moved.
1.5x + 6 = 4.5x - 9
1.5x - 4.5x = -9 - 6
-3x = -12
Move -3 to the right side to solve for x. Multiplication becomes division after being moved to the other side
-3x = -12
x = -12/-3
x = 4
The value of x is 4
P = 2L + 2W, keep that in mind (W=width, L=length)
Just fill it in. 82=2(5+2w) + 2w. First solve for w.
82 = 10+ 10w + 2w,
82 = 10 + 12w. Now subtract the 10 from both sides, and get:
72 = 12w, now divide both sides by 12, and get:
6 = w.
W is 6.
Now to solve for L, go back to the problem we had, L = 5 + 2w. Fill in w,
L = 5 + 2(6), and then it is L = 5 + 12.
It is a simple addition equation now.
L = 17, W = 6
