Answer:

7x - 3y = -12

Step-by-step explanation:

5(0-1) + 3y = 7(x + 1)

using BODMAS to solve

5(-1) + 3y = 7(x + 1)

-5 + 3y = 7x + 7

7x - 3y = -5 - 7

7x - 3y = -12

When you want to round a number, there are some rules.

1. If the number you are rounding is followed by 5, 6, 7, 8, 9, then round the number up, that is add 1 to it.

2. If the number you are rounding is followed by 0, 1, 2, 3, 4, then round the number down, that is add 0.

Now if given a number and you are asked to round to the nearest 100, 1 000, 10 000 and so on, then for nearest 100, count 2 numbers from the back. Whatever number you stop at, that is the number you are to round. For 1000 count 3, for 10 000 count 4 and so on.

Since Kiara is having the same value after rounding, it means she picked a number that has zeros after the 10 000th value

Let's assume she picked: 70 000

Rounding that number to nearest 100, 1000 and 10000 gives the same number which is

70 000.

Step-by-step explanation:

If we use both hoses, we fill the pool at 40 + 60 = 100 gallons per hour.

The volume of the pool is 60 * 300 = 45 * 400 = 18,000 gallons.

Hence, we need 18,000 / 100 = 180 hours.

Line C does not follow the trend of points. Lines A and B have an excess number of points above their lines. Only Line D has a relative equal number of points above and below the line.

The answer is D.

The solution is, The graph that best approximates the line of best fit is option D.

Here, we have,

we know that,

Line of Best Fit:

This refers to the line that is used in a scatter plot to show and indicate a relationship between the points so that the number of points above the line is equal to the points below the point.

Line C does not follow the trend of points. Lines A and B have an excess number of points above their lines. Only Line D has a relative equal number of points above and below the line.

Hence, from the given illustration of graphs, we can see that using the eyeball method, we can see that the number of points in option D is best balanced between the line above and below.

The answer is D.

The answer you have clicked is correct

Step-by-step explanation:

To get x alone you need to get rid of the 4 so you subtract it from both sides

so then you have

x + 4 - 4 = 24 - 4

the fours on the left cancel out

x = 24 - 4

subtract

x = 20

Two or more expressions with an Equal sign is called as Equation.6(3-5w)=5(4-2w)-20w have no solution

Two or more expressions with an Equal sign is called as Equation.

The given equation is 6 times of three minus five w equal to five times of four minus two w minus twenty w.

6(3-5w)=5(4-2w)-20w

Apply distributive law on LHS side

6(3)-6(5w)=5(4)-5(2w)-20w

18-30w=20-10w-20w

Let us take all the variable w terms to one side

18-20=30w-10w-20w

Step-by-step explanation:

The first humor bookshelf in the section of a library can hold 2296, books. The bookshelf has 7 shelves. Shelves. Each shelf can hold the same number of books. How many books can each shelf​ hold? Write an equation to help solve this problem.

They said each shelf can hold the same number of books

And we have 7 shelves

Total number of books = 2296

Hence:

The number of books each shelf can hold = 2296 books/7 Shelves

= 328 books

Hence, each shelf can hold 328 books

Step-by-step explanation:

The volume of this cube is  1 cu.cm , Option B is the correct answer.

A cube is a three dimensional shape having 6 square faces , all the faces are of equal length , breadth and height.

The volume of the cube is given by side * side * side

Let side =  a

Then volume of the cube = a³

In the given figure all the side of the cube is given as 1 cm.

Therefore to determine the value of the volume , we will substitute in the equation

Answer:

They would be done by 2 :  18 AM

Step-by-step explanation:

Key Information:

- Stacey starts at 2 PM peeling 20 potatoes per hour

- Rob starts at 3 PM peeling 30 potatoes per hour

- James starts at 4 PM peeling 40 potatoes per hour

At 5pm;

Stacy would have worked for 3 hours and would have peeled ( 3 * 20 = 60 potatoes)

Rob would have worked for 2 hours and would have peeled ( 2 * 30 = 60 potatoes)

James would have worked for an hour and would have peeled ( 1 * 40 = 40 potatoes)

Total number of potatoes peeled at 5pm = 60 + 60 + 40 = 160 potatoes

Potatoes left = 1000 - 160 = 840 potatoes.

The new peeling rate for three of them combined is (20 + 30+ 40 ) = 90 potatoes per hour.

Rate = potatoes left / time;

Time = Potatoes / Rate

Time = 840 / 90 = 9.3 hours = 9 hours 18 minutes

Total time taken = 9 hours 18 minutes + 3 hours = 12 hours 18 minutes

They would be done by 2 :  18 AM

Answer:

2:20 am

Step-by-step explanation:

Stacey's start time = 2 pm

Rate = 20 per hour

Rob start time = 3pm

Rate = 30 per hour

James start time = 4pm

Rate = 40 per hour

Number of potatoes = 1000

By 4 pm when James started :

(2 * 20) + (1 * 30) = 40 + 30 = 70

Potatoes left at 4pm = 1000 - 70 = 930 potatoes

Number of potatoes peeled per hour staring from 4 pm:

20 + 30 + 40 = 90 potatoes

Time taken to peel 930 potatoes will be :

930 / 90 = 10.333333 hours

(0.33333 * 60) = 19.9998 minutes

10.3333 hours = 10 hours 19.99998 minutes = 10 hours 20 minutes

Hence, from 4pm = 4pm + 10 hours 20 minutes = 2 : 20 a. M

Step-by-step explanation:

In Quadrant II, cosine is negative.

We know that sin²x + cos²x = 1, so:

cosx = sqrt[1 - sin²x]

= sqrt[1 - (5/13)²]

= sqrt(144/169)

= -12/13 (since cosx is negative here)

The answer is -12/13. (B)

Option B is correct.

According to the given question

We have,  sin ∅ = 5/13

From the trigonometric identities we know that

[tex]sin^{2}[/tex]∅ + [tex]cos^{2}[/tex]∅ =1

substitute the value of sin∅ in the above identity

[tex](\frac{5}{13} )^{2} + cos^{2}[/tex]∅  =1

⇒ [tex]\frac{25}{69} +cos^{2}[/tex]∅  =1

⇒ [tex]cos^{2}[/tex]∅ = 1 - [tex]\frac{25}{169}[/tex]

⇒ [tex]cos^{2}[/tex]∅ = [tex]\frac{169-25}{69} =\frac{144}{169}[/tex]

⇒[tex]cos[/tex]∅ = [tex]\sqrt{\frac{144}{169} }[/tex]

⇒cos∅ = ±[tex]\frac{12}{13}[/tex]

Since, ∅ is in quadrant II, then cos<0

⇒ cos∅ = -[tex]\frac{12}{13}[/tex]

Hence, option B is correct.
