Product of -4 and a number x   is  -4 * x = - 4x

-4x  + 2  < 20

Answer:

Step-by-step explanation:

Turning the word problem into equations:

[tex]-4x+2 = 20[/tex]

Subtracting 2 on both sides

[tex]-4x+2 -2= 20 -2[/tex]

[tex]-4x = 18[/tex]

Dividing by -4

[tex] -4x/(-4) = 18/(-4)[/tex]

Considering that -4x/(-4) = x

Then the answer is x = -18/4 = - 9/2 = - 4 1/2

Answer:

6 packs of sugar cookies and 10 packs of chocolate chip cookies.

Step-by-step explanation:

Let the quantity of sugar cookies be x packs and the quantity of chocolate chip cookies be y packs. Total packs are 16. Therefore: x + y = 16. This implies y = 16 - x (Equation 1).

It is given that a pack of sugar cookies is priced at $2.5 and a pack of chocolate chip cookies is priced at $3.5. It is also given that the student spends a total of $50 on the cookies. Since x packs of sugar cookies and y packs of chocolate chip cookies are to be bought, therefore:

2.5x + 3.5y = 50 (Equation 2).

Put equation 1 in equation 2.

2.5x + 3.5(16 - x) = 50.

2.5x + 56- 3.5x = 50.

-x = -6.

x = 6.

Put x = 6 in equation 1.

y = 16 - 6.

y = 10.

Therefore, Angelina will buy 6 packs of sugar cookies and 10 packs of chocolate chip cookies!!!

Question Explanation:

In other words you can write 200,00 using a whole number and a power 10 using scientific notation!

In scientific notation you want a number less than 10 multiplied by 10 to the power of a number.

-----------------------------------

Solution:

200,000 / 10 = 20,000

20,000 / 10 = 2,000

2,000 / 10 = 200

200 / 10 = 20

20 / 10 = 2

I divided 200,000 by 10 five times to get a number less than 10.

So, 5 is going to be the exponent.

-----------------------------------

Answer:

2 x 10^5

-----------------------------------

Hope This Helped! Good Luck!

200,000 can be expressed as 2 x 10^5 in scientific notation, which helps to simplify handling of large and small numbers by reducing the number of zeros.

To express 200,000 using a whole number and a power of 10, we need to move the decimal place. Start by writing the number as 2 followed by five zeros, or 2,00000. The power of 10 is determined by the number of places we move the decimal. In this case, the decimal is moved 5 places to the left, so we use 10 to the power of 5. Thus, 200,000 can be written as 2 x 105.

This method is known as scientific notation or powers-of-ten notation. It simplifies dealing with very large and small numbers by reducing the number of zeros we have to keep track of. It also makes mathematical operations easier. For instance, when multiplying numbers in this notation, we need to multiply the numbers out front and then add the exponents.

Answer:

69.1

Step-by-step explanation:

Mean height of 14 students = 69.0 inches

Mean = sum of data/number of data

69 = sum of data/14

sum of data = 966

FOR NEW MEAN:

Height of additional student = 70.5

Mean = sum of data/ number of data

Mean = 966+70.5/14+1

Mean = 1036.5/15

Mean = 69.1

Therefore, the mean height of the 15 students in the class is 69.1

Final answer:

To find the new mean height after Danielle joins the class, calculate the total height of all students, add Danielle's height, and divide by the new number of students. The mean height increases to 69.1 inches.

Explanation:

Mr. Zuro finds the mean height of all 14 students in his class to be 69.0 inches. When Danielle, who is 70.5 inches tall, walks in late, we need to calculate the new mean height of all 15 students.

First, we find the total height of the initial 14 students by multiplying the mean height by the number of students: 69.0 inches × 14 = 966 inches. Next, we add Danielle's height to this total: 966 inches + 70.5 inches = 1036.5 inches. Finally, to find the new mean height, we divide this total by the number of students, now 15: 1036.5 inches ÷ 15 = 69.1 inches.

Therefore, the mean height of the 15 students in the class, including Danielle, is now 69.1 inches.

Translate

Step-by-step explanation:

To shift a graph vertically and/or horizontally is to  Translate it.

Translation--

A translation is a rigid transformation in which the graph of the original function is shifted some units to the left or to the right( i.e. horizontal shift) or some units up or down ( i.e. vertical shift ).

The horizontal shift of the function f(x) by k units is given by:

   f(x) → f(x+k)

and the vertical shift of the function f(x) by k units is given by:

   f(x) → f(x)+k

7766 rounded ot the nearest thousands would be 8000, since the hundreds place value, 7, is going to be rounded up to 8000.

Hope this helped!

Answer:

8000

Step-by-step explanation:

|Thousands||Hundreds||Tens||Ones|

|       7          ||        7       ||   6  ||    6   |

5 or more, raise the score (turn the 7 into an 8 and make the three other numbers 0)

4 or less, let it rest (leave the 7 as a 7 and make the other 3 numbers 0).

The number that we are looking at changing will be bold. The number that determines if we change that number will be underlined.

7766

The 5 or more, raise the score rule applies to 7.

So, we will make the 7 thousand (7000) 8 thousand (8000)

We will make the seven hundred sixty six (766) zero (0).

Answer:

x = - 8, x = 6

Step-by-step explanation:

Given

(x - 6)(x + 8) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 8 = 0 ⇒ x = - 8

Answer:

x =  -8, 6.

Step-by-step explanation:

(x– 6)(x + 8) = 0

Either factor can be zero:

x - 6 = 0 gives x = 6 and

x + 8 = 0 gives x = -8.

Answer:

y = - 6x - 19

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 6x - 4 ← is in slope- intercept form

with slope m = - 6

• Parallel lines have equal slopes, thus

y = - 6x + c ← is the partial equation

To find c substitute (- 3, - 1) into the partial equation

- 1 = 18 + c ⇒ c = - 1 - 18 = - 19

y = - 6x - 19 ← in slope- intercept form

Final answer:

To find 15% of 75% of 80, calculate 75% of 80 first (0.75  imes 80 = 60), then find 15% of 60 (0.15  imes 60 = 9), resulting in an answer of 9.

Explanation:

The student has asked: What is 15% of 75% of 80?

To solve this problem, we'll need to follow these steps:

First, find 75% of 80.

Then, find 15% of the result from step 1.

Let's start with the first step:

75% of 80 is equivalent to 0.75  imes 80, which equals 60.

Now, for the second step:

15% of 60 is equivalent to 0.15  imes 60, which equals 9.

Therefore, 15% of 75% of 80 is 9.
