5000x0.75+3000 should give you your answer. I think it's the 3rd one because 0.75+3000=3000.75.

Answer:

B

Step-by-step explanation:

Here, we want to choose the equation representing the time it will take if they worked together

Let the amount of tasks to be done be t

pedro will work at a rate of t/3

Camela will take t/2

So the joint rate will be

t/2 + t/3

This joint rate will be equal to 1

Thus, we have

t/2 + t/3 = 1

Answer:

The concept of percent increase is basically the amount of increase from the original number to the final number in terms of 100 parts of the original. An increase of 5 percent would indicate that, if you split the original value into 100 parts, that value has increases by an additional 5 parts.

Answer:

B. 14%

Step-by-step explanation:

To find the percent decrease, find the difference between the two prices then divide it by the original price:

50 - 43 = 7

7/50

= 0.14

So, the percent decrease is B, 14%

10 strawberries

Step-by-step explanation:

If Mike can pick 50 strawberries in 5 minutes then it is safe to assume that for 1 minute, Mike can pick 10 strawberries since you divide 50 by 5 in which Mike can pick a strawberry for every 6 seconds.

Step-by-step explanation:

Domain & Range is just x and y.

the function includes x values between & including -2 and 2, while y includes 3, and -3

Answer:

x < 1

Step-by-step explanation:

x is less than 1, we can see

we have an open circle, so x is only less than 1

it does not include 1

so answer is x < 1

Answer:

The x coordinate of the solution to the system of equations is 8

Step-by-step explanation:

We need to find the x coordinate of the solution to the system of equations?

[tex]x- 5y =23\\-2x - 6y =2[/tex]

Let

[tex]x- 5y =23--eq(1)\\-2x - 6y =2--eq(2)[/tex]

Multiply equation 1 with 2 and add both equations

[tex]2x- 10y =46\\-2x - 6y =2\\-------\\-16y=48\\y=\frac{48}{-16}\\y=-3[/tex]

So, we get the value of y = -3

Now, for finding x, put value of y in equation 1

[tex]x- 5y =23Put\:y=-3\\x-5(-3)=23\\x+15=23\\x=23-15\\x=8[/tex]

So, we get x = 8

The solution set is (8,-3)

So, the x coordinate of the solution to the system of equations is 8

Answer:

65 miles per hour.

Step-by-step explanation:

To find the unit rate, we need to figure out how far we travel in one hour.

325/5 = 65/1

We travel 65 miles in one hour.

Answer:

65 mph (miles per hour)

Step-by-step explanation:

Because unit rate is a rate where the second quantity is one unit.

And to find miles per hour in this equation you have to divide 325 miles by 5 (because it is 5 hours) and you get 65.

Answer:

you have to use the slope equation, which is (y2-y1) / (x2-x1)

3. (5-0)/(1 -(-8))

5/1+8

5/9

4. (3-3)/(-4 -8)

0/-12

the slope is 0

6. (-2-8)/(1-0.5)

-10/0.5

-20

7. (7-(-1))/ (4-4)

7+1/0

8/0

the slope is undefined

Answer:

It is an arithmetic sequence

Common difference is -4

Step-by-step explanation:

Here, we want to determine the type of sequence

As we can see, the difference between each of the terms is as follows;

13-17 = 9-13 = -4

What this mean is that we have a constant common difference

This simply shows that the sequence we have is an arithmetic sequence

The common difference is thus;

13-17 = 9-13 = -4

Answer:

B

Step-by-step explanation:

1) lets use elimination to solve this:

multiply 10x+4y=24 with 3 in order to get "4y" into "12y"

3(10x+4y=24)

30x+12y=72

now subtract both equations to eliminate 'y"

30x+12y=72

-

6x+12y=48

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

24x=24

x=1

now substitute 1 in the above equation:

6(1)+12y=48

6+12y=48

12y=42

y=7/2

Answer:

The correct option is;

D. -8·t² + 18·t + 6 = 10

Step-by-step explanation:

The given equation of the height toy cannon launched on top of a platform is given as follows;

h(t) = -8·t² + 18·t + 6...(1)

Where "h" represents the height in meters, at time "t" seconds after the ball is launched

When the height is 10 meters, we can write as follows;

The height of the ball, h(t) = 10

Therefore, by substituting the value of h(t) in equation (1), h(t) = -8·t² + 18·t + 6, when h(t) = 10 we get;

-8·t² + 18·t + 6 = 10.

Answer:

a=121/2

Step-by-step explanation:

Answer:

multiply by 5, t = 14.5

Step-by-step explanation:

t/5 = 2.9 (multiply each side by 5)

t = 14.5

Using the Pythagorean Theorem, it is found that he would travel 92 miles farther by  walking from his home to his friend's house and then from  his friend's house to work than he would travel by walking  from his home directly to work.

The Pythagorean Theorem states that, on a right triangle, the length of the hypotenuse squared is the sum of the length of each leg squared, that is:

[tex]h^2 = l_1^2 + l_2^2[/tex]

Walking from his home to his friend's house and then from  his friend's house to work, Jardon travels 240 + 120 = 360 yards.

Directly from his home to work, the distance is the hypotenuse of a right triangle with legs [tex]l_1 = 240, l_2 = 120[/tex], hence:

[tex]d^2 = 240^2 + 120^2[/tex]

[tex]d = \sqrt{240^2 + 120^2}[/tex]

[tex]d = 268[/tex]

360 - 268 = 92

He would travel 92 miles farther by  walking from his home to his friend's house and then from  his friend's house to work than he would travel by walking  from his home directly to work.
