Answer:

20 inches

Step-by-step explanation:

Step 1: Subtract the total from what was left

$95 - 15 = 80$

Step 2: Divide the result into the 4 pieces

$80 \div 4$

$=\frac{80}{4}$

$= 20$

Each of the four pieces Lily cut was 20 inches.

Each was 10 inches because she had 95 and 95-15=40 divided by 4 = 10

The length of a rectangle is three less than four times the width. The perimeter of the rectangle is 54 feet. Find the width of

kirill115 [55]

Answer:

6 ft

Step-by-step explanation:

Let the width = w

Then the length = 4w - 3

perimeter = 2(length + width)

perimeter = 2(4w - 3 + w)

perimeter = 2(5w - 3)

perimeter = 10w - 6 = 54

10w - 6 = 54

10w = 60

w = 6

Answer: The width is 6 ft

The relationship between the number of pentagons and the perimeter will be

$x=1,y=15,(x,y)=(1,15)\\x=2,y=29,(x,y)=(2,29)\\x=3,y=43,(x,y)=(3,43)$

From the diagram in the question, each side of a pentagon has length $3units$ .

Also, each time another pentagon is attached, a side is removed.

Using these observations, we can create a relationship between the number of pentagons, $x$ , and the perimeter, $y$ , as follows

For $x=\text{number of sides}=1$

$y=\text{perimeter}=3\times 5=15units$

For $x=2$

$y=3\times5+3\times5-1\\=15+15-1\\=29units$

For $x=3$

$y=3\times5+3\times5-1+3\times5-1\\=3\times5+3\times5+3\times5-1-1\\=15+15+15-2=43units$

The relationship will be

$x=1,y=15,(x,y)=(1,15)\\x=2,y=29,(x,y)=(2,29)\\x=3,y=43,(x,y)=(3,43)$

Gunther invested $10,000 in two mutual funds. One of the funds rose 6% in one year and the other rose 9% in one year. If his inv

mote1985 [20]

Answer:

$7200 in the fund rose 6% n $2800 in the fund rose 9%

Step-by-step explanation:

let x be the amount in the fund rose 6%

gain in one year=x*6%=0.06x

total amount is 10000

so amount in the fund rose 9% = 10000-x

gain in one year=(10000-x)*9%=900-0.09x

total gain=0.06x+900-0.09x=900-0.03x

=684

900-684=0.03x

0.03x=216

x=7200

the other fund amount=10000-7200=2800

If DE = 4 x + 10, EF = 2 x -1, and DF = 9 x - 15, what is the length of DF?

maria [59]

Answer:

DF = 57

Step-by-step explanation:

DE + EF = DF

(4x + 10) + (2x - 1) = 9x - 15

Combine like terms on the left side

6x + 9 = 9x - 15

Subtract 6x on both sides

9 = 3x - 15

Add 15 on both sides

24 = 3x

Divide by 3 on both sides

x = 8

DF = 9x - 15 = 9(8) - 15 = 72 - 15 = 57

Checking:

(4(8) + 10) + (2(8) - 1) = 9(8) - 15

(32 + 10) + (16 - 1) = 72 - 15

58 - 1 = 72 - 15

57 = 57
