what is to 20 ≥ 4/5w

Answers

20 ≥ 4/5w
w<= 20 (5/4)
w <= 25

hope it helps
Final answer:

The inequality 20 ≥ (4/5)w represents a comparison between a number and a variable multiplied by a fraction. To solve it, you isolate the variable. The solution is w <=25.

Explanation:

The inequality 20 ≥ (4/5)w represents a mathematical statement comparing a number, 20, with a variable, w, multiplied by a fraction, 4/5. The inequality sign, ≥, indicates that 20 is greater than or equal to the result of the multiplication. To solve this inequality, you need to isolate the variable on one side of the inequality sign.

To get rid of the fraction, multiply both sides of the inequality by the reciprocal of 4/5 which is 5/4. This gives you (5/4) * 20 ≥ (5/4) * (4/5)w which simplifies to 25 ≥ w.

Therefore, the solution to the inequality is w <=25.

-12 ÷ 3 x (-8 + (-8) - 6) + 2

Prepare you response to this question when you are ready you may submit your response

Requirements: include various key words you learned within this unit.
list your steps in order so that anyone can follow

Answers

Use the order of operations in order to simplify (solve) the expression

-12 ÷ 3 x (-8 + (-8) - 6) + 2      Original expression
-12 ÷ 3 x (-16- 6) + 2              Inside the parenthesis do the addition of the first negatives. -8 +-8 = -16
-12 ÷ 3 x (-22) + 2                 Inside the parenthesis subtract -16-6 = -22
-4 x (-22) + 2                       Multiplication and division is worked from left to right. -12 divided by 3 is -4
88 +2                                  Multiply -4 x -22 = 88. Two negatives make a positive with multiplication.
90                                       Addition 88 + 2 = 90
The expression must be simplified using the order of operations. In this case, the terms inside the parenthesis should be simplified first. Within the parenthesis, there is a nested parenthetical term, which is simplified before the rest of the term inside the parenthesis. The +(-8) term simplifies to -8. The terms inside the parenthesis then become (-8-8-6), which is equal to -22. Then, multiplication and division are performed next, in order as they appear. So -12/3 is equal to -4. Then, -4 is multiplied by the -22 from the parenthetical expression to equal 88. Then, addition and subtraction are the final steps in the order of operations, so the 2 is added to the 88, for a total of 90.

Find x value for the point that splits segment CD in half if point C is located at (−2, 4) and point D is located at (3, 7).

Answers

The x value is 1/2, or 0.5

Just use the midpoint formula
(x2+x1)/2 , (y2+y1)/2

to find the midpoint. The x value would be (x2+x1)/2, so plug in the numbers.
(-2+3)/2 = 1/2

Answer:

[tex]\text{The x value for the point that splits segment CD in half is }\frac{1}{2}[/tex]

Step-by-step explanation:

Given two points C(-2,4) and D(3, 7)

we have to find the value of x-coordinate for the point that splits segment CD in half.

By mid-point formula,

The coordinate of mid-point of line segment joining the points (a,b) and (c,d) are [tex](\frac{a+c}{2}, \frac{b+d}{2})[/tex]

Coordinates of mid-point joining the points C(-2,4) and D(3, 7)

[tex](\frac{-2+3}{2},\frac{4+7}{2})[/tex]

[tex](\frac{1}{2},\frac{11}{2})[/tex]

Reggie lost 4 spaceships in level 3 of a video game. He lost 30 points for each spaceship. When he completed level 3, he earned a bonus of 350 points. By how much did his score change?

Answers

his score changed by 320. to get the answer, just subtract 30 from 350 and you get 320.
He lost 4 spaceships, each subtracting 30 points

4(-30) = -120

On completing, he earned a bonus of 350 points
0 + 350 = 350

Subtract the amount of points he lost from the bonus

350 - 120 = 230

His score has a positive 230, or x (total points he gotten) plus the bonus

x + 230

Find the equation of a line that is parallel to the line x= -14 and contains the point (-4,2)

Answers

Two lines that are parallel have the same slope.

The given line, x = -14, is a vertical one.  Its slope (rise/run) is undefined due to division by zero.  Any line parallel to x = -14 is also vertical.  Since the new line goes through (-4,2), the equation of the new line is x = -4.
Final answer:

The equation of the line that is parallel to x = -14 and passes through the point (-4, 2) is x = -4.

Explanation:

The line x = -14 is a vertical line. Any other line parallel to it would also be a vertical line. The equation of a vertical line in the 2-dimensional coordinate space takes the form x = k, where k is a constant. To find the equation of a line that is parallel to x = -14 and passes through the point (-4, 2), we just need to substitute the x-coordinate of the point into the equation, resulting in x = -4.

The distance between bills house and his aunts house is 485 miles about how many miles would bill drive if he made 4 round trips from his house to his aunts house

Answers

He would have made 1,940 miles in total

Answer:

3880 miles

Step-by-step explanation:

Distance between Bill's house and his Aunt house = 485 miles

Distance traveled in one round trip = two times the distance between the Bill's house and his Aunt house

Distance traveled in one round trip = 2 x 485 = 970 miles

So, the distance traveled in 4 round trip = 4 x 970 = 3880 miles.

Thus, the distance traveled by teh bill in 4 round trips is 3880 miles.

I am an odd number, I am less than 100, the sum of my digits is 12, I am a multiple of 15. What number am I

Answers

Final answer:

The number is 75, which satisfies all given conditions: it is an odd number, less than 100, a multiple of 15, and the sum of its digits is 12.

Explanation:

To find an odd number that is a multiple of 15, less than 100, and has a sum of digits that equals 12, we must first consider that multiples of 15 end with a 5 or 0. Since the number is odd, it must end with a 5. Additionally, the number must be less than 100, so we are looking for a two-digit number.

We know the sum of the digits is 12, and since the last digit is 5, the first digit must be 7 to reach a sum of 12 (7+5=12). This means the number we are looking for is 75, which is indeed a multiple of 15, less than 100, has a sum of digits equal to 12, and is an odd number.

Describe the solutions of 4 + n > −2 in words.

The value of n is a number less than −6.
The value of n is a number greater than or equal to −7.
The value of n is a number equal to −7.
The value of n is a number greater than −6.

Answers

Final answer:

The solution to the inequality 4 + n > -2 is n > -6. This means the value of n can be any number that is greater than -6.

Explanation:

The inequality 4 + n > -2 can be solved to find the solution for 'n.' Start by subtracting 4 from each side of the inequality to isolate 'n.'

Here's the step-by-step calculation: 4 + n > -2 becomes n > -6 when we subtract 4 from both sides.

So, the value of n is any number that is greater than -6. In other words, n can be just a little bit more than -6, -6.01 for example, or it can be a much larger number, like 1, 100, or 1000, etc.

Thanks!1Coral reefs are amazing underwater worlds. They cover about 186,000 square miles of ocean floor. They mostly exist in the warmest parts of the world. This is because coral reefs develop in shallow, warm water, usually near land and mostly in the tropics. Coral reefs prefer temperatures between 70 and 85 degrees Fahrenheit. This is why they are found off the coasts of Africa, India, Australia, and Brazil. Coral reefs closest to us are found off the coast of Florida.2Coral reefs are made up of groups of sea animals called coral polyps. These animals attach to each other and work together to keep the water safe for the plants and animals that live there. Their hard skeletons remain when they are no longer alive. The stony structures they form provide protection and shelter for many different kinds of plants and fish.3Fish, clams, sponges, sharks, and sea turtles are only a few of the thousands of creatures that call coral reefs their home. Many of the plants and fish that live in coral reefs depend on one another to live and grow. People also depend on coral reefs. The reefs contain many plants and animals used in medicines, chemicals, or other products we need to lead healthy lives.
