This inequality can be simplified.

~Divide -1 to both sides (flip the symbol since we're dividing a negative number)

-m/-1 < 15/-1

m < -15

Best of Luck!

Answer:

m < -15

Step-by-step explanation:

Step 1:  Multiply both sides by -1

-m > 15

-m * -1 > 15 * -1

Since you multiply by a negative, you must flip the sign

-m * -1 > 15 * -1

m < -15

Answer:  m < -15

For this case we must simplify the following expression:

[tex](9x ^ 2 + 10x + 4) - (9x ^ 2 + 5x-1)[/tex]

We eliminate the parentheses taking into account that:

[tex]- * + = -\\- * - = +\\9x ^ 2 + 10x + 4-9x ^ 2-5x + 1 =[/tex]

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

[tex]9x ^ 2-9x ^ 2 + 10x-5x + 4 + 1 =\\5x + 5[/tex]

Answer:

100 is grace's initial amount. w is how much of the substance is being decrased each week. in ryan's equation, 1 is 100% of the substance, so the initial amount, and 0.4 is the amount that is being decreased.

Step-by-step explanation:

Answer:

100= Initial Amount

1/4= decay factor for each week

w= number of weeks

1/4w= decay factor after w weeks

1 - 0.4= decay factor for each week

w= number of weeks

0.4= percent decrease

Answer:

x = 1 and y = - 4

Step-by-step explanation:

The equation of a vertical line is

x = c

where c is the value of the x- coordinates the line goes through.

Here the line passes through (1, - 4) with x- coordinate 1, thus

x = 1 ← equation of vertical line

The equation of a horizontal line is

y = c

where c is the value of the y- coordinates the line goes through.

Here the line passes through (1, - 4) with y- coordinate - 4, thus

y = - 4 ← equation of horizontal line

Eric took 20 hours to do the job alone.

Step-by-step explanation:

Given :

The amount of work Joe alone can do per hour = 75/5 = 15 packages.

The amount of work Joe and Eric together do per hour = 75/4 = 18.75

The amount of work Eric alone can do per hour = 18.75 - 15 = 3.75

The time Eric took to complete the entire work = 75 / 3.75 = 20 hours.

Solution:

Given that,

Gavin ran 10 MPH during Monday's workout

50% slower during Tuesday's workout

Therefore,

Speed in tuesday = 50 % slower than monday

Which means,

Speed in tuesday = 10 - 50 % of 10

Solve the above

[tex]\text{ Speed in tuesday } = 10 - \frac{50}{100} \times 10\\\\\text{ Speed in tuesday } = 10 - 0.5 \times 10\\\\\text{ Speed in tuesday } = 10 - 5\\\\\text{ Speed in tuesday } = 5\\\\[/tex]

Thus, he ran 5 mph in tuesday

Answer:

3(3b + 4)

the GCF is 3

Step-by-step explanation:

20k/20⁴=20⁹

20k=20⁴×20⁹=20¹³

k=20¹³/20=20¹²

Answer: k=20¹²

The value of k in the equation (20k)/(20⁴) = 20⁹ is k = 20¹¹.

To solve for the value of k in the equation (20k)/(20⁴) = 20⁹, we can follow these steps:

1. Simplify both sides of the equation:

(20k)/(20⁴) = 20⁹

So, (20k)/(20⁴) = (20⁴)²

2. Evaluate the exponent on the right side:

(20k)/(20⁴) = 20⁸

3. Multiply both sides by (20⁴) to eliminate the denominator on the left side:

[(20k)/(20⁴)] * (20⁴) = (20⁸) (20⁴)

Simplifying the left side:

20k = 20¹²

4. Divide both sides by 20 to solve for k:

(20k)/20 = (20¹²)/20

k = 20¹² / 20

5. Further simplify the right side:

k = 20¹¹

Therefore, the value of k in the equation (20k)/(20⁴) = 20⁹ is k = 20¹¹.

Step-by-step explanation:

to get the answer you should add up the amount of chocolate chip and peanut butter cookies to get your total and then put it over the total amount of cookies you have

The probability of randomly choosing a chocolate chip or peanut butter cookie from the bag is 22/25 or 0.88 (rounded to two decimal places).

The probability of randomly choosing a chocolate chip or peanut butter cookie can be found by adding the probabilities of choosing a chocolate chip cookie and a peanut butter cookie.

The probability of choosing a chocolate chip cookie is the number of chocolate chip cookies in the bag divided by the total number of cookies:

P(chocolate chip) = 15/25 = 3/5

The probability of choosing a peanut butter cookie is the number of peanut butter cookies in the bag divided by the total number of cookies:

P(peanut butter) = 7/25

So, the probability of choosing a chocolate chip or peanut butter cookie is:

P(chocolate chip or peanut butter) = P(chocolate chip) + P(peanut butter)

P(chocolate chip or peanut butter) = 3/5 + 7/25

P(chocolate chip or peanut butter) = 15/25 + 7/25

P(chocolate chip or peanut butter) = 22/25

Therefore, the probability of randomly choosing a chocolate chip or peanut butter cookie from the bag is 22/25 or 0.88 (rounded to two decimal places).

The distance from home to school will be 5 meters.

Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

From the given image the distance between the home and school is followed by the square 3 meters from the home and the school is 4 meters making a right-angle triangle.

The minimum distance between the school and the home will be calculated as;-

D = √ ( 3² + 4² )

D = √ ( 25 )

D = 5 meters'

Step-by-step explanation:

The sum of interior angles of the quadrilateral that has vertices at the center of the Earth, the two points of tangency, and the satellite is 360°. The angles at the points of tangency are 90°, so the angle at the satellite and the central angle are supplementary.

The arc has a measure of 180° -135° = 45°.
