Answer:%28a-b%29%2Fb=c

a-b=bc

a=bc%2Bb

 

a=b%28c%2B1%29

a%2F%28c%2B1%29=b

b=a%2F%28c%2B1%29

So the answer is b=a%2F%28c%2B1%29

Danny is 603/4 inches tall . His twin sister is 58 1/8 inches tall.How much taller is Danny than his twin sister.
Mazyrski [523]

Answer:

2 5/8 inches

Step-by-step explanation:

This is a subtraction problem.

You must subtract 58 1/8 inches from 60 3/4 inches.

We need a common denominator for the fractions.

The LCD of 4 and 8 is 8.

60 3/4 = 60 6/8

58 1/8 = 58 1/8

60 3/4 - 58 1/8 = 60 6/8 - 58 1/8 = 2 5/8

Answer: 2 5/8 inches

I would like to create a rectangular vegetable patch. The fencing for the east and west sides costs $4 per foot, and the fencing
loris [4]
The answer to this question:
<span>north and south sides 16ft
east and west sides 8ft
</span>
In this question, the east and west fencing cost is $4/ft but the south and north fencing cost is $2/ft. The cost is cheaper for fencing north and south side which cost half of the east and west side. The perimeter is made by adding the south, north, east and west side.
If x = north and south fencing and y= is east and west side, then you can get this equation

cost= (south+north) * $2 + (east+west)*$4  
128=(x+x) * 2 + (y+ y) * 4
128= 4x + 8y
32= x+ 2y
x= 32-2y

The area is count by multiplying the width and length, which was x and y in this question. The formula should be:
area= length * width
area= x * y
area= (32-2y) * y
area= 32y - 2y^2

Then, you need to find the value of y needed for the maximum area.
32y- 2y^2 
32 - 2*2y=0
32= 4y
y= 8

If y=8 then
x= 32-2y
x= 32- 16= 16
