The perimeter of a rectangle is 20 feet. The width is 4 feet less than the length. Find the dimensions of the rectangle. Then find its area.

Answers

Answer:

length = 7 ft

width = 3 ft

area = 21 sq ft

Step-by-step explanation:

let l = length

let l - 4 = width

2l + 2(l - 4) = 20

2l + 2l - 8 = 20

4l = 28

l = 7

w = 3

Area: 7 x 3 = 21

Answers

Answer:

23

Step-by-step explanation:

Use the part/whole = %/100.

You have that whole = 115 and % = 20, so that would be:

[tex]part/115=20/100[/tex]

simplify & solve:

[tex]part/115=1/5[/tex]

multiply both sides by 115

[tex]part=115/5\\part = 23[/tex]

-12(5/6a-7/8)+1/14(3 1/2a-1 2/5)

Answers

-12(5/6 a -7/8) + 1/14(3 1/2 a- 1 2/5)

First change mixed fractions to be full fractions

-12(5/6 a -7/8) + 1/14 (7/2 a - 7/5)

Now multiply out

-12(5)/6 a -12(-7)/8) + 7/14(2) a -7/14(5)
-60/6 a + 84/8 + 7/28 a -7/70
-10a + 10.5 + 1/4a - 1/10
-10a + 0.25a +10.5 -0.1
-9.75a + 10.4

*if this =0 and you need to solve for a then
9.75a=10.4
a= 10.4/9.75
a=16/15

You can buy 12 cookies for $4. What is the unit rate for the cost of each cookie?​

Answers

Answer:

$0.33 per cookie

Step-by-step explanation:

The unit rate (cost per cookie) is

     $4

---------------- = $0.33 per cookie

12 cookies

Answer:

Roughly $0.34

Step-by-step explanation:

Set up an equation:

Variable x = cost of one cookie

12cookies/$4 = 1cookie/x

12/4 = 1/x

Cross multiply

12 × x = 4 × 1

12x = 4

Divide both sides by 12

12x ÷ 12 = 4 ÷ 12

1x = 4/12

x = 0.333333

x = is about $0.34

Hi there! :)

[tex]\large\boxed{A = 12.5 \text{ units}^{2}}[/tex]

Find the area of the shape using the formula for the area of a trapezoid:

A = 1/2(b1 + b2) · h

Where:

b1 = base 1

b2 = base 2

h = height

A = area

Plug in the given bases and height:

A = 1/2(7.5 + 2.5) · 2.5

Simplify:

A = 1/2(10) · 2.5

A = 5 · 2.5

A = 12.5 units²

Answer:

  x ∈ {2.07014981016}

Step-by-step explanation:

The equation can be rewritten as ...

  √x = 18-8x

  x = 324 -288x +64x²

  64x² -289x +324 = 0

  x = (289 ±√577)/128 ≈ {2.07015, 2.44548}

Since √x must be positive, we know that ...

  18 -8x ≥ 0

  x ≤ 18/8 = 2.25

The larger of the above solutions is extraneous, so the solution set is ...

  x ∈ {(289 -√577)/128} ≈ {2.07015}

I think x is 15 because you set each side equal to each other to find x

Answer:

x=15

Step-by-step explanation:

Hello there!

The shown angles are vertical angles

if you didn't know vertical angles are congruent

That being said we can create equation

5x + 40 = 115

now we solve for x

step 1 subtract 40 from each side

40 - 40 cancels out

115 - 45 = 75

now we have 75 = 5x

step 2 divide each side by 5

5x/5=x

75/5=15

we're left with x = 15
