Answer:

B) 72

Step-by-step explanation:

The value of 80-2n when n=4 can be found by substituting n=4 into the expression and simplifying. Therefore:

80-2n = 80 - 2(4) = 80 - 8 = 72

Therefore, the answer is B) 72.

[tex] \sf80 - 2n[/tex]

Put n = 4

[tex] \tt80 - 2 \times 4 \\ \tt80 - 8 \\ \boxed{ \sf\underline{ \underline{72}}}[/tex]

Step-by-step explanation:

1/10 is equal to .1

Answer:

As a mixed number it would be 1 3/7

2 different fractions could be 20/14 and 40/28

10/7 x 2 = 20/14

10/7 x 4 = 40/28

Answer:

20x - 21y + 14 (first option)

Step-by-step explanation:

30x - 16y + 10 - 10x - 5y + 4

20x - 21y + 14

The slope of a line can be found using the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are two points on the line.

Plugging in the given points, we get:

m = (-4 - (-7/2)) / (2 - (-3)) = 3/2 / 5 = 3/10

So, the slope of the line is 3/10, which is equal to one tenth.

Therefore, the answer is "one tenth."

Answer:

27 found this answer in ohio

Step-by-step explanation:

We want to multiply the following 2 fractions:

3

4

x

36

1

Multiplying 2 fractions involves multiplying both numerators divided by both denominators.

Numerator 1 x Numerator 2

Denominator 1 x Denominator 2

In this case, Numerator 1 = 3, Denominator 1 = 4, Numerator 2 = 36, Denominator 2 = 1, so we have:

3 x 36

4 x 1

108

4

Now that we have our preliminary answer, we need to reduce it down as much as possible.

From our GCF Calculator, we see that the highest number that reduces 108 and 4 down to an integer is 4.

This number, 4, is called our Greatest Common Factor (GCF), and will be used to reduce both numerator and denominator as seen below.

Reducing the numerator gives us: (1/4) x 108 = 27

Reducing the denominator gives us: (1/4) x 4 = 1

Our answer is just the reduced numerator divided by the reduced denominator.

Since our reduced answer is a whole number, we remove the one from the denominator and write it as:

Answer = 27

Answer:

It's -17x + 505

Step-by-step explanation:

The linear equation  is like y=mx+b

Solve it by using linear equation knowledge: because the graph is going down, or the height is descending, so the the slope must be negative.

And the choise of slope is 505, 17, -17, 17, so the one with negative: -17 slope is correct.

Answer:

17x + 505

y=MX+b

Solve it by using a linear equation,  the graph is going down the slope must be negative

-17 slope is The Right answer for you.

Answer:

55 to 90 for math; 50 to 90 for language arts

Step-by-step explanation:

The correct statement regarding the middle 50% of the data-sets is given as follows:

60 to 85 for math; 60 to 80 for language arts.

From left to right, the five features of the box and whisker plot are listed as follows

The middle 50% of a data-set is given by the interquartile range of the data-set, which is the difference between the upper quartile and the lower quartile of the data-set.

On the box plot, the middle 50% is given by the ends of the box.

#SPJ1

Answer: The circumference of the cylinder's base is 6 units.

Radius = 1/2(6/pi)

Volume = r2pi*h

h = (27/2) / r2pi

sin(∠BAD) = h / 6

Answer: Company B charges $0.08x + $30.00 more than Company A for x miles.

Step-by-step explanation:

The total cost for Company A for x miles is 0.09x + 30.50, and the total cost for Company B is 0.17x + 60.50. To find how much more Company B charges than Company A for x miles, we can subtract the cost of Company A from the cost of Company B:

(0.17x + 60.50) - (0.09x + 30.50)

Simplifying the expression, we get:

0.08x + 30.00

Therefore, Company B charges $0.08x + $30.00 more than Company A for x miles.

Answer:

Now you can divide 4/9 by many fractions:

  1 x 4/9 = 4/9

Step-by-step explanation:

====================================================

Explanation:

Let's label the given points A, B and C

To move from B to C, we do two things in either order:

This motion of "down 2, right 7" is copied or mirrored when we go from A to D. This is to ensure that BC is parallel to AD.

Start at point A and go down 2 units to get to (-6, -4). Then move 7 units to the right to arrive at (1, -4) which is the location of point D. You can use a tool like GeoGebra to verify the answer is correct.

Answer:

a) 2/7 cup

b) k = 2/7

Step-by-step explanation:

2 cups of red paint (R) require 7 cups of white paint(W)

We can write this as a proportion equation:
R = k.W

where k is the constant of proportionality

Given R =2 when W = 7 we get

2 = k . 7

k = 2/7

Constant of proportionality = 2/7

So for 1 cup of White paint we will need
R = 2/7 x 1 = 2/7 cup

Understand:

You are looking for the price of 4 pairs of shoes after 20 days of being on sale. You have $100 and you have to find out whether you can buy these shoes.

How to solve:

After 20 days 1 pair of shoes will cost:

$40/1 x 2/5 = 16$

40-16 = 24

So 1 pair of shoes will cost $24 after 20 days.

24x4 = $96

4 pairs of shoes after 20 days cost $96. We have 100$, So we will be able to purchase it.
