Write the equation in slope intercept form: -6x+4y=20

Answer:

W=x/7+ 8z/7 + 4/7

Step-by-step explanation:

As a result, the total distance traveled by Mary in her round trip is 3/2 mile + 3/2 mile = 6/2 mile = 3 mile

We can calculate the total distance traveled by a body with position function s (t) if it moves along a coordinate line without changing direction from t = a to t = b. If the body changes direction during the journey, we must integrate the body's speed |v (t)| to find the total distance traveled.

Therefore,

We know Mary spent only a third of the time coming from school as she did going because she traveled three times as fast coming from school as she did going to school (6 miles per hour versus 2 miles per hour). If x represents the time it took her to get to school, then x/3 represents the time it took her to return.

Knowing that the total trip took 1 hour, we have:

x + x/3 = 1

3x/3 + 1x/3 = 1

4x/3 = 1

x  = 3/4

So we know it took Mary 3/4 of an hour to get to school (and 1/4 of an hour to get home).

Remembering that distance = rate × time, Mary's commute to school was (2 miles per hour) × (3/4 of an hour) = 3/2 mile. Furthermore, because she returned via the same route, she must have traveled 3/2 of a mile.

As a result, the total distance traveled by Mary in her round trip is 3/2 mile + 3/2 mile = 6/2 mile = 3 mile.

Exact number of steps taken by Anne to cross the road either by striding 80cm or by striding 70cm , then the least width of the road is equal to 5.6meters.

As given in the question,

Anne takes exact number of steps to cross the road either by striding 80cm or by striding 70cm.

Conversion of the units

1 meter = 100 centimeters

1 centimeter = 1/100 meter

80 cm = 80 /100

          = 0.8 meters

70 cm = 70 /100

          =0.7 meters

Least width of the road is calculated by finding least common multiple of 0.8 meters and 0.7 meters

0.8 = 8 × (1/10)

0.7 = 7 × (1/10)

least common multiple = 7 × 8 × (1/10)

                                    = 5.6 meters

Therefore, exact number of steps taken by Anne to cross the road either by striding 80cm or by striding 70cm , then the least width of the road is equal to 5.6meters.

Answer:

1.95 hours or 1 hour and 57 minutes.

Step-by-step explanation:

You can read the problem as 13% of the battery. "Of" is a keyword that means to multiply.

The battery lasts 15 hours, so multiply by 13%. You need to change 13% to a decimal first by dividing it by 100, or moving the decimal left two places.

13% = 0.13

Now solve.

0.13 × 15 = 1.95

If you need to convert the 0.95 to minutes, multiply it by 60 since there are 60 minutes in an hour.

0.95 x 60 = 57 minutes.

The next place value on the right should be used to round a number to the closest tenth (the hundredths). Simply take away all the digits to the right if it's 4 or fewer. Remove all the digits to the right after adding 1 to the digit in the tenths position if the number is five or above.

To what decimal place do you round?

Examine the hundredth number to determine the decimal number's nearest tenth. Add one to the tenth value if the number is more than 5. Remove all the numbers that are present after the tenth place if the value is less than 5, but keep the tenth place value in place otherwise. As an illustration, if you want to round up to the nearest.

Answer:

x = -2

Step-by-step explanation:

7/(2x) - 2/x + 1 = 1/4

7/(2x) - 4/(2x) + 1 = 1/4

(7-4)/(2x) = 1/4 - 1

3/(2x) = 1/4 - 4/4

3/(2x) = - 3/4

3 = (-3/4)(2x)

3 = -6x/4

3*4 = -6x

12 = -6x

12/-6 = x

-2 = x

Check:

7/(2*-2) - 2/-2 + 1 = 1/4

7/-4 + 1 + 1 = 1/4

-7/4 + 2 = 1/4

-7/4 + 8/4 = 1/4

The probability that the score of a randomly selected examinee is less than 370 is 0.113

Mean of the gmat score = 410

Standard deviation of the deviation = 33

The randomly selected examinee be X ,

Thus X = 370

So , we need to find the probability that the score of a randomly selected examinee is less than 370 i.e.

   P(X < 370)

Now , let us the z-score with normal distribution formula

        Z = (X - μ) / σ

        Z = (370 - 410) / 33

        Z = -40 / 33

       Z = -1.21

Thus P(X < 370) = P(Z < -1.21)

From the z - table , we can get that

         P(Z < -1.21) = 0.11314

By rounding off to three decimals ,

          P(Z < -1.21) = 0.113

Therefore , the probability of Z< -1.21 is 0.113

Answer:

To stay within budget, she must use 3.9 gigabytes.

Caroline can use approximately 3.9 gigabytes of data while staying within her budget of $74 per month.

Let's assume the number of gigabytes of data Caroline can use while staying within her budget is represented by the variable "x."

The flat cost per month is $54.50, and Caroline pays an additional $5 per gigabyte.

If she wants to keep her bill at $74 per month, the equation can be set up as follows:

54.50 + 5x = 74

To solve for "x," we can isolate the variable on one side of the equation. First, subtract 54.50 from both sides:

5x = 74 - 54.50

5x = 19.50

Finally, divide both sides by 5:

x = 19.50 / 5

Simplifying the division gives us:

x = 3.9

Therefore, Caroline can use approximately 3.9 gigabytes of data while staying within her budget of $74 per month.

EXPLANATION

You had $30 yesterday and you spent 20% of it today.

Since you spent 20% of it, the percentage you will have left is:

100 - 20 = 80%

So, you have 80% of $30.

That is:

You have $24 left.

The number of pages that Kamala needs to reach each day is p ≥ 30.

Here are inequality signs and what they mean:

The inequality sign that would be used is ≥. This is because the pages Kamala needs to read each day  can be equal to 235 or greater than 235

25 + 7p ≥ 235

Combine similar terms: 7p ≥ 235 - 25

Step-by-step explanation:

You want the value of a^2 +b^2, given that 'a' and 'b' are roots of the polynomial x^2 +7x -2.

If the roots are 'a' and 'b', then the factored form is ...

  (x -a)(x -b) = x^2 -(a+b)x +ab

Comparing this to the given polynomial, we see that ...

  -(a+b) = 7

  ab = -2

The expression a^2 +b^2 can be written as the sum ...

  a^2 +b^2 = a^2 +2ab +b^2 -2ab = (a+b)^2 -2ab

Using the values of (a+b) and ab from above, we see that ...

  a^2 +b^2 = (-7)^2 -2(-2) = 49 +4 = 53

The cost of the jam Elmo uses to make the sandwiches =$1.65

What is the cost of the jam Elmo uses to make the sandwiches?

B globs of Peanut butter at 4 cents = 4B

J blobs of Jam at 5 cents = 5J

The number of sandwiches is given by the linear equation,

N(4B + 5J ) =$ 2.53

N(4B + 5J ) = 253 cents    ---(1)

The factors of 253 = 1, 11, 23, 253.

Since N > 1 , N is 11 or 23

Considering N = 11

11(4B + 5J ) = 253

4B + 5J  = 23   ---(2)

The possible values of B and J to satisfy the linear equation:

B = 2 and J = 3

Substituting B and J in (2)

4B + 5J  = 23

4 (2) + 5(3) = 23

8 + 15 = 23

23 = 23

The linear equation is verified.

The cost of jam Elmo uses to make the sandwiches =N( 5J)

                                                                                       =11 (5*3)

                                                                                       = 11 *15

                                                                                        = 165 cents or $1.65
