the width of a rectangle is half of the length of the rectangle. if the perimeter is 84 inches what is the length of the rectangle?

Answers

Answer 1

Answer:

The length of the rectangle is 28 inches.

Step-by-step explanation:

We have that the width (W) of a rectangle is half of the length (L) of the rectangle:

[tex] W = \frac{1}{2}L [/tex]  (1)

Also, the perimeter is 84 inches:

[tex] P = 2W + 2L = 84 in [/tex]   (2)

By entering equation (1) into equation (2) we have:

[tex]2(\frac{1}{2}L) + 2L = 84 in[/tex]

[tex] L = \frac{84}{3} = 28 in [/tex]

Therefore, the length of the rectangle is 28 inches.

I hope it helps you!

Answers

15 and a half (15.5) quarts

Get each in common units

Orange 2 gallons X 4 quart per gallon = 8 quarts
Pineapple 4 quarts no change

\begin{aligned} &-x+4y=-9 \\\\ &y=-2x +6 \end{aligned} ​ −x+4y=−9 y=−2x+6 ​ Is (2,3)(2,3)left parenthesis, 2, comma, 3, right parenthesis a solution of the system?

Answers

Answer:

NO

Step-by-step explanation:

Given the system of equation

-x+4y = -9,... 1

y = -2x+6.... 2

To find the solution to the equation

Substitute equation 2 into 1

-x+4(-2x+6) = -9

-x-8x+24 = -9

-9x= -9-24

-9x = -33

x = 33/9

Find y

y = -2x+6

y = -2(33/9)+6

y = -66/9 + 6

y = -66+54/9

y = -12/9

y = -4/3

Hence (2,3) is not the solution to the system of equation

Them sum of two numbers is 17. One number is 3 less than 2/3 of the numbers. What is the lesser number?

Answers

Answer:

The smaller number is 5

Step-by-step explanation:

Let the smaller number be x

the other number is (17 -x) (we know they add up to 17)

2/3 of the bigger number is written as 2/3 (17 - x)

The smaller number is 3 less than that. (so subtract 3 to get x)

x= 2/3 (17 -x) - 3 <-- We have an equation, solve for x

Check 2/3 x 12 - 3 = 8 - 3 = 5

The vegetable garden has 95 ripe plants. The number of tomatoes is 16 fewer than twice the number of squashes. How many of each vegetable are ripe?​

Answers

Answer:

Tomatoes = 39.5

Squash = 55.5

Step-by-step explanation:

T (tomatoes) = S - 16

S + T = 95

we plug it in now

S + (S - 16) = 95

2s = 95 + 16

2s = 111

s = 55.5??

hm. Let's go with it

T = 55.5 - 16

T = 39.5

39.5 + 55.5 = 95

Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?

Answers

Answer:

We can make the paint amount equal by making sure the parameters have the same unit

Step-by-step explanation:

Billy had 5 gallons of paint. Bob had 4 kilograms of paint. How do you make the paint amount equal?

To solve the above question, we have the conversion rate:

We can make the paint amount equal by making sure the parameters have the same unit

Hence:

1 gallon (gal) = 3.785411784 kilogram (kg).

Billy had 5 gallons of paint.

1 gallon (gal) = 3.785411784 kilogram (kg).

5 gallons of paint = x

Cross Multiply

x = 5 × 3.785411784 kg

18.92705892 kilograms of paint

Approximately 18.93 Kilograms of paint

Therefore, Billy had 18.93 kg of paint and Bob had 4 kg of paint

Answers

Answer:

x= 2 or x= -3

Step-by-step explanation:

Bring the equations together using a common denominator (x-5) (x+7)

x-29/(x-5) (x+7)= 1

Multiply both sides by (x-5) (x+7)

x- 29= (x-5) (x+7)

x- 29= (x-5) (x+7)= x^2 + 2x - 35

-x^2 - x + 6 = 0

-(x-2)(x+3)= 0

Multiply both sides by -1

(x-2)(x+3)= 0

Split it into two equations

x-2= 0 or x+3= 0

x= 2 or x= -3

Find the height of a triangle whose base is 5 inches and area is 12 square inches.

Answers

12 divided by 5. = 2.4 inches

Answer:

Therefore, Height = 4.8 inches.

Step-by-step explanation:

Given : A triangle whose base is 5 inches and area is 12 square inches.

To find : Find the height of a triangle.

Solution : we have given

Triangle base = 5 inches.

Area = 12 square in.

We need to find height of the triangle.

Area =  * base * height .

Plugging the values .

12 =   * 5 * height .

On multiplying both sides by 2

24 = 5 * height .

On dividing both sides by 5.

Height = 4.8 inches.

Therefore, Height = 4.8 inches.
