The width of Jeff's rectangular garden is 6 feet shorter than its length, and its area is equal to 667 square feet. Which equation can be used to find the possible values for the length of Jeff's garden, x?

So you use the point slope stuff.

y-y=m(x-x)

To find the slope, subtract two y values over two x values that are also sibtracted in the same order.

IN this case, you could do (-4 - 23)/-5 - 10

Which is 9/5

So now you plug in the x and y values (doesnt matter which point)

y+4=9/5(x+5)

Make it slope intercept form

y=9/5x-13

 x = 2

22x = 44

22x/ 22 = 44 / 22         -Divide both sides by 22

x = 2

Hope this helps! If so, please mark brainliest!

the square root of 9 would be 3. as 3 x 3 =9

the square root of any number is asking what number times itself will give you the given number you are trying to square root. for example, the square root of 36 would be 6, as 6 x 6 = 36. I hope this helped

Doing a square root of one digit numbers is just multiplying by 2 so 18 is your answer.

Answer:

The length is 5.7 feet.

Step-by-step explanation:

A rectangle has a width of 7.9 feet and a perimeter of 27.2 feet.

Let the length be = x

Perimeter is given by :

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

We get;

[tex]27.2=2(x+7.9)[/tex]

=> [tex]27.2=2x+15.8[/tex]

=> [tex]2x=11.4[/tex]

Dividing both sides by 2 to get x;

x = 5.7 feet

Hence, length is 5.7 feet.

Julie's age based on the scenario given cab be obtained by using the equation ; j + 2j - 6 = 36

Let :

Julie's age = j ________(1)

Helga's age = 2j - 6 ____(2)

Sum of their ages = 36

Hence, to find Julie's age, j we can use the equation :

(1) + (2) = 36

j + (2j - 6) = 36

j + 2j - 6 = 36

To find Julie's age, we can use the equation ;

j + 2j - 6 = 36

3j - 6 = 36

3j = 36 + 6

3j = 42

j = 42 / 3

j = 14

Hence, Julie's age is 14 years.

No, what Joe said isn't necessarily true. Though it is common that the product will be a 4 digit number, because you can use any number, like a large 4 digit number like 9999 or a large 1 digit number like 9, that isn't true. For instance: "9999 x 9" is 89991 which is 5 digits instead of 4 because "9999" is the biggest 4 digit number and "9" is the biggest "1" digit number.

Answer:

Z=3

Step-by-step explanation:

divide both sides of the equation by 4

subtract 5 from both sides of the equation

4*(z + 5) = 32

4z + 20 = 32

4z = 32 - 20

4z = 12

z = 12 : 4

z = 3

2. Tom's brother saw Muscle Fitness, which offers $20 off of the $80 fee. Membership is $15 a month plus another $5 a month.

First, solve the one time fee

$80 - 20 = $60

Next, solve the monthly fee

15 + 5 = 20

(a) The expression: Let x = month

20x + 60

(b) Remember the previous question.

Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month.

(a) Write a expression to represent the membership cost of Platinum Gym for x months.

Let x = months

20x + 60 is your expression

No. In fact, it will be the same. Waiving the $20 off the one-time fee would give the same amount of one-time payment, 60. Membership and Mandatory equipment maintenance would also add up to $20 a month.

Solve. Note the equal sign. What you do to one side, you do to the other. Remember to follow PEMDAS.

First, distribute 5 to all terms within the parenthesis

5(w - 1) = (5)(w) + (5)(-1) = 5w - 5

Next, simplify. Combine like terms

5w - 5 - 2 = 5w + 7

5w - 7 = 5w + 7

Next, isolate the variable. Add 7 to both sides, and subtract 5w from both sides

5w (-5w) - 7 (+7) = 5w (-5w) + 7 (+7)

5w - 5w = 7 + 7

600t = 480(18 – t) should be it

Answer:

Option D. 600t = 480( 18-t )

Step-by-step explanation:

An airplane flew at an average rate of 600 miles per hour fro Tokyo to Seattle.

Let the airplane travels for t hours so distance covered by the airplane will be = speed × time

    = 600t miles

Similarly, average speed in return trip was 480 mile/hour. So distance covered in return trip = speed × time

= 480 ( 18-t ) [ since time taken by plane in round trip was 18. So time taken in return trip will be ( 18-t) ]

Therefore, distance traveled in one trip = distance covered in return trip

600t = 480( 18-t )

Option D is the answer.

Answer:

16 meter per second.

Step-by-step explanation:

A race horse that wins three 3200 meter cup in a time of 200 seconds.

Since in 200 seconds horse can run = 3200 meter

Therefore, in 1 second horse can run = [tex]\frac{3200}{200}[/tex]

                                                              = 16 meter/second

1 hour = 3600 seconds

Therefore in 1 hour horse can run = 3600 × 16

                                                        = 57,600 meter/hour

The average speed of the horse would be 16 meter per second or 57,600 meter per hour.

answer is 2720

solution below

First, converting R percent to r a decimal

r = R/100 = 4.5%/100 = 0.045 per year.

solving our equation:

A = 2000(1 + (0.045 × 8)) = 2720  

A = $2,720.00

the total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 4.5% per year for 8 years is $2,720.00

17,000 is the answer

6 is the thousand digit and we always want to round when we do thousands to the nearest hundred and since she rounded it to the nearest hundred first it should look like this 16,500 then rounded to the nearest thousand is 17,000 we always round up when we have a number more then 5 and round down less than 5.

positive = greater than 0.

Therefore we have the inequality:

[tex]x-7 > 0[/tex]       |add 7 to both sides

[tex]x > 7[/tex]

Answer:

  The interest rate = 6 %

Explanation:

We have  I = prt, where I represents simple interest, p represents principal, r represents interest rate, and t represents time in years.

 Here principal, p = 200 $

          Number of years , t = 3

        Interest received, I = 36$

       We need to find rate of interest.

Substituting

       36 = 200 x r x 3

      r = [tex]\frac{36}{200*3}[/tex]= 0.06 = 6%

  The interest rate = 6 %

Answer:20%

Step-by-step explanation:

Let r represent rate of interest.

We have been given that Mika invested $200 into a certificate of deposit. After 6 months, the balance was $220.

We will use simple interest formula to solve our given problem.

I = Amount of interest,

P = Principal amount,

r = Rate of interest in decimal form,

t = Time in years.

First of all, we will find amount of interest by subtracting $200 from $220 as:

6 month = 1/2 year = 0.5 year

Upon substituting our given values in simple interest formula, we will get:

Upon dividing both sides by $100, we will get:

Since interest rate is given in decimal, so we will multiply 0.2 by 100 to convert our answer in percentage.

Therefore, the interest rate on the deposit was 20% and option B is the correct choice.

The point (-4,15) is found in the second quadrant, where x-values are negative (here, -4) and y-values are positive (here, 15) in the Cartesian coordinate system.

The point (-4,15) lies in the second quadrant of the Cartesian coordinate system. In the second quadrant, the x-coordinate is negative and the y-coordinate is positive. This is because the Cartesian coordinate system is divided into four quadrants based on the signs of the x (horizontal) and y (vertical) values: Quadrant I (positive x, positive y), Quadrant II (negative x, positive y), Quadrant III (negative x, negative y), and Quadrant IV (positive x, negative y).

Let Angle A = X

Since Angle B is the same, angle B is also X

Then angle C = X +45

Add the 3 angles together: X +X +X +45 = 3x+45

That equals 180 degrees:

3x+45 = 180

Subtract 45 from both sides:

3x = 135

Divide both sides by 3:

X = 135/3

X = 45

Angle A = 45

Angle B = 45

Angle C = 45+45 = 90
