The quotient of a number decreased by 7 and -2 is -10.

Answers

Answer 1

Step-by-step explanation:

First, a quotient is the answer to a division equation.

So its like y÷z=x

X is our quotient.

Since x is -10 when decreased by 7 and -2, we can write:

x-7-(-2)=-10

x-7+2=10

x-5=10

x=15

We now know that x is 15.

Using that, we can write out our equation.

Since you say do not solve, i have purposefully NOT solved this.  

You should use y as a dividend and z as a divisor!

Good luck.

For the table

How do u get the slope?

Answers

Slope in fraction form = 3/2

Slope in decimal form = 1.5

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

Explanation:

That table shows the two points (x1,y1) = (-14,-18) and (x2,y2) = (-10,-12).

Each row is a different point.

To find the slope, we subtract the y values to get y2-y1 = -12-(-18) = -12+18 = 6

Then we subtract the x values to get x2-x1 = -10-(-14) = -10+14 = 4

Lastly, we divide the two differences: ydiff/xdiff = 6/4 = 3/2

The slope in fraction form is 3/2, which is equivalent to the decimal form 1.5

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

If you want, you can apply the slope formula like so

m = slope

m = rise/run

m = (change in y)/(change in x)

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

m = (-12-(-18))/(-10-(-14))

m = (-12+18)/(-10+14)

m = 6/4

m = 3/2

m = 1.5

We effectively are following the same as steps as before, but in this format, it's more of what you might have on your homework if you were to show the step-by-step process. You could also do a visual graph approach as a different option. Often in math there are multiple ways to get the answer.

The figure is made up of a semicircle and a triangle. Find the perimeter. Round your answer to the nearest hundredth.

Answers

Answer:

Solution:

Here,

The perimeter of of the whole figure is 134.57ft.

Step-by-step explanation:

Here,

The perimeter of semicircle = (22/7) x 25ft

= 78.57ft

Now,

The perimeter of triangle = 7ft + 24ft + 25ft

= 56ft

Again,

The perimeter of whole figure = perimeter of semicircle +perimeter of triangle

= 78.57ft + 56ft

= 134.57ft

Answers

Answer:

A: 479.94/6

B: D, 56.79

C: 79.99 and 56.79

D: Obviously 79.99 is greater than 56.79 so the slope in question A is greater than the slope in B (C)

Step-by-step explanation:

Question A:

For this one we will let x= nights in a hotel and y=cost

We can then just pick two points on the table and plug in the numbers to the formula above

Let's pick the first and last one

our two ordered points are (0,20) (6,499.94)

We can plug this in and get

(499.94-20)/(6-0) which simplified to 479.94/6

Question B:

This equation is in slope intercept form

Slope intercept form is as follows

y=mx+b

where m is the slope and b is the y intercept

we can see that the m value is 56.79 which means D is the answer

Question C:

This is pretty easy

First divide 99.8/2 and get 49.9 and the other answer is just 56.79

Answer:

A: 479.94/6

B: D, 56.79

C: 79.99 and 56.79

D: Obviously 79.99 is greater than 56.79 so the slope in question A is greater than the slope in B (C)

please help me with this for brainliest and a cupcake

Answers

Answer:

Step-by-step explanation:

Example

With numbers

18+4=22

18+4−4=22−4

18=18

With variables and numbers

x+4=22

x+4−4=22−4

x=18

We subtract 4 from both sides. Example

Which of the following numbers is a solution to the equation? x = 2, 7,  or 8?

14−x=7

Here you are given the numbers 2, 7 and 8. One of these numbers will satisfy the equation. If you don't know the solution right away, you can investigate which of the given numbers gives results in the correct answer by plugging in the different values of x.

Answer: x=7

Example

8x=64

8⋅x=64

Which number should you multiply 8 by to get a product of 64? By using the multiplication table, we know that the number is 8.

8⋅8=64

When we solve an equation, we figure out what value of x (or any other variable) makes the statement true (satisfies the equation).

Answer: r = 39. Add 17 to both sides and you’re left with r on the left and 39 on the right.

x = 6

Step-by-step explanation:

10 - 4 = 6

The x means the number is unkown, well, we know that 6+4=10, so there you go!

Answer:

6

Step-by-step explanation:

x is a mystery number. We don't know what it is, but we know that if you add 4 to it, we get 10. To what number should we add 4 to get 10?

That's right, 6.

A more advanced explanation:

We need to isolate x, so it will be alone on one side of the equation. To do this, we must subtract 4 from the left side of the equation, so it will be x + 0, or x. But we also need to remember that equations always need to be balanced, so we need to subtract 4 from both sides, to get x + 0 = 10 - 4. Simplifying, we get that x = 6.

Above lone woodland ways that led To dells the stealthy twilights tread The west was hot geranium red; And still, and still, Along old lanes the locusts sow With clustered pearls the Maytimes know, Deep in the crimson afterglow, We heard the homeward cattle low, And then the far-off, far-off woe Of "whippoorwill!" of "whippoorwill!"II. Beneath the idle beechen boughs We heard the far bells of the cows Come slowly jangling towards the house; And still, and still, Beyond the light that would not die Out of the scarlet-haunted sky; Beyond the evening-star's white eye Of glittering chalcedony, Drained out of dusk the plaintive cry Of "whippoorwill," of "whippoorwill."III. And in the city oft, when swims The pale moon o'er the smoke that dims Its disc, I dream of wildwood limbs; And still, and still, I seem to hear, where shadows grope Mid ferns and flowers that dewdrops rope, Lost in faint deeps of heliotrope Above the clover-sweetened slope, Retreat, despairing, past all hope, The whippoorwill, the whippoorwill.Whippoorwill - a nocturnal bird with a distinctive call that is suggestive of its namePart AWhat is a theme of The Whippoorwill?Memories of our past will always linger.Peace found in nature can sustain one in the city.The mind can play tricks on a person.One can find serenity and hope in nature.Question 2Part BHow does the theme in Part A develop in the poem?Even though the moon is hidden by smoke in the city, the speaker thinks of the sights and sounds of the country.The speaker regrets his move to the city and thinks only of his time in the countryside.Coming home in the evening to his place in the city, the speaker hears a whippoorwill.The countryside is full of the sounds of nature and the call of the whippoorwill. tatiana, conoces a las hermanos de Andres?
