Answer:
x= 44 ounces y = 66 ounces
Step-by-step explanation:
Distribution would be an increase to find 80% salt.
Where we use 4/5 = 80 but use here 4/5.
We find 19/20 but just say 95 for solution B =
Let x = the number of ounces of Solution A
Let y = the number of ounces of Solution B
x + y = 110 y = 110 - x
(70x + 95y) = 4/5 x 110
70x + 95y = 88
70x + 95 y = 88
70x + 95 (88 - x) = 8800 make units equal or for start convert decimalization = same units as 2nd multiplied value.
70x + 8360 - 88x = 8800
-10x - 8360 - 8800 = y
-10x = 440
x = 44 ounces
y = 110- 44
y = 66 ounces
2(x+4)=18
2•x + 2•4 = 18
2x + 8 = 18
2x + 8 = 18
- 8 -8
_________
2x = 10
2x = 10

÷2 ÷2
x = 5

Let us assume the width of the rectangle = x cm
Then
The length of the rectangle = (x + 4) cm
It is already given that
Perimeter of the rectangle = 80 cm
Now we also know the formula for perimeter of a rectangle
Perimeter = 2 ( length + width)
80 = 2 (x + 4 + x)
80 = 2 (2x + 4)
80/2 = 2x + 4
40 = 2x + 4
Dividing both sides by 2 we get
20 = x + 2
20 -2 = x
x = 18
Then
Width of the rectangle = 18 cm
Length of the rectangle = (18 + 4) cm
= 22 cm
So the rectangle has a length of 22 cm and a width of 18 cm.
