Each team in a soccer league has 43 players on it. There are 24 teams in the league. How many total players are in the league?

Let the speed of the boat in still water = X

The current is 3 mph, so the speed of the boat going upstream would be x-3

Speed of the boat going down stream would be x +3

The trip upstream is 26 / x-3

The trip downstream is 38 / x+3

Set them to equal and solve for x:

26/x-3 = 38/x+3

Multiply both sides by (x+3)(x-3):

38(x-3) = 26(x+3)

Simplify:

38x - 114 = 26x+78

Subtract 26x from each side:

12x -114 = 78

Add 114 to each side:

12x = 192

Divide both sides by 12:

x = 192 / 12

x = 16

The speed is 16 miles per hour.

To determine the boat's speed in still water, an equation is set up that relates the upstream and downstream times, given that the current influences the boat's effective speed by 3 mph. Solving this equation yields a speed of 16 mph for the boat in still water.

To find the speed of the boat in still water, we need to account for the effect of the current on the boat's speed when going up and down the river. Let the speed of the boat in still water be v mph.

When the boat is going upstream (against the current), its effective speed is (v - 3) mph because the current slows the boat down by 3 mph. When the boat is going downstream (with the current), its effective speed is (v + 3) mph because the current speeds the boat up by 3 mph.

Since the boat covers 26 miles upstream and 38 miles downstream in the same time, we can set the time equal for both scenarios:

Time = Distance / Speed

By equating the two times, we get:

26 / (v - 3) = 38 / (v + 3)

To solve for v, cross-multiply and simplify:

26(v + 3) = 38(v - 3)

26v + 78 = 38v - 114

12v = 192

v = 192 / 12

v = 16 mph

Therefore, the speed of the boat in still water is 16 mph.

To solve this, write an equation to model the situation and solve the equation.

The equation can be: [tex]3(x-9)=27[/tex]

Then solve the equation.

Luigi is 15 years old.

we determine that Luigi is 15 years old.

The question involves solving for Luigi's age based on the given relationship between Mario and Luigi's ages. We are told that Mario's age is three times the difference between Luigi's age and the number 9, and that Mario is currently 18 years old. We need to create an equation and solve for Luigi's age.

Let's let L represent Luigi's age. The problem statement tells us:

Mario's age = 3 * (L - 9)

Given that Mario's age is 18, we substitute this value into the equation:

18 = 3 * (L - 9)

To find L, we start by dividing both sides of the equation by 3:

6 = L - 9

Then, we add 9 to both sides to solve for L:

15 = L

Therefore, Luigi is 15 years old.

Matthew traveled a total of 43 blocks.

To calculate the total blocks traveled by Matthew, we need to add up the distances he walked and the distances he rode on the bus. He walked 7 city blocks, rode 13 blocks on the bus, and then walked 1 and a half blocks to the store. To return home, he traveled the same route, so we can double the distance. Adding all these distances together, Matthew traveled a total of 7 + 13 + 1.5 + 7 + 13 + 1.5 = 43 blocks.

Answer:

120:300 is in the same ratio as 2:5. Can you add the pound sign? My keyboard does not have it.

Step-by-step explanation:

Add the two parts of the ratio together

2 + 5 = 7

Find 5:7

5:7 = x:420  

5/7 = x/420              Cross multiply

7x = 5 * 420             Combine the right

7x = 2100                  Divide by 7

x = 2100/7

x = 300                      

Find the second number

420 - 300 = 120

120 : 300 is the answer

Divide top and bottom by 60

120/60 = 2

300 / 60 = 5

Let cost of Emma's phone = x

Given that cost of Sophie's phone = 640

Then ratio of their phones cost will be x:640 or x/640

Given that ratio of their phones cost is 7:8 or 7/8

So both ratios will be equal.

[tex]\frac{x}{640}=\frac{7}{8}[/tex]

[tex]x=\frac{7}{8}*640[/tex]

x=560

So the new ratio of the cost of their phones will be 560:640

Now we have to find about how much should the prices of their phones decrease in order to have a ratio of 9:11.

So let that decreased amount is k then we will get equation :

[tex]\frac{560-k}{640-k}=\frac{9}{11}[/tex]

11(560-k)=9(640-k)

6160-11k=5760-9k

6160-5760=11k-9k

400=2k

200=k

Hence final answer is prices of their phones should decrease by 200 in order to have a ratio of 9:11.

If the speed in still air is s, and the wind speed is w,

580/(s+w) = 5

580/(s-w) = 10

s=87

w=29

Final answer:

To determine the speed of the plane in still air and the speed of the wind, we use the distances and times provided to create two equations. Solving this system reveals that the speed of the plane in still air is 87 mph and the speed of the wind is 29 mph.

Explanation:

To find the speed of the plane in still air and the speed of the wind, we can set up a system of equations based on the given information. We'll let p represent the speed of the plane in still air and w represent the speed of the wind.

When the plane travels with the wind, its effective speed is p + w, and the time taken for the trip is 5 hours, covering 580 miles. So, our first equation is:

1) (p + w) * 5 = 580

When the plane returns against the wind, its effective speed is p - w, and the time taken for this trip is 10 hours, again covering 580 miles. Thus, our second equation is:

2) (p - w) * 10 = 580

Solving this system of equations, we'll start by simplifying both:

p + w = 116 (By dividing the first equation by 5)

p - w = 58 (By dividing the second equation by 10)

Now we can add both equations to eliminate w:

2p = 174

Divide by 2 to get the speed of the plane in still air:

p = 87 mph

To find the speed of the wind, substitute the value of p in one of the equations:

87 + w = 116

So, the speed of the wind is:

w = 116 - 87

w = 29 mph

The speed of the plane in still air is 87 mph, and the speed of the wind is 29 mph.

Hey there!!

Given :

Sum of two integers = -5 and the product is -36.

Hence,

... x + y = -5

... xy = -36

x + y = -5

... y = -x - 5

xy = -36

...x ( -x - 5 ) = -36

... -x² - 5x = -36

... x² + 5x - 36 = 0

This can't be factored so solve using quadratic equation

x = [-b ±√(b2-4ac)]/2a      a=1, b=5, c = -36

x = [-5±√(52-4(-36))]/2

x = [-5 ±√169]/2

x = (-5 ± 13)/2

x = (-5+13)/2= 8/2 = 4  OR

x = (-5-13)/2 = -18/2 = -9

x = 4, -9

Note here that since x+y=-5

For x=4, y=-9

for x = -9, y = 4

The two numbers are 4, -9

Hope my answer helps!!

The two integers are 4 and -9.

To find the two integers, let's assume that one integer is x and the other integer is y. Since the sum of the two integers is -5, we can write the equation x + y = -5. Similarly, the product of the two integers is -36, so we can write the equation xy = -36.

Now, we can solve these equations simultaneously to find the values of x and y.

From the first equation, we can express x in terms of y as x = -5 - y. Substituting this value into the second equation, we get (-5 - y)y = -36.

Simplifying this equation gives us y^2 + 5y - 36 = 0. Factoring or using the quadratic formula, we find that y = -9 and y = 4.

Substituting these values back into the equation x = -5 - y, we find that x = 4 and x = -9.

Therefore, the two integers are 4 and -9.

Step-by-step explanation:

Assume camel stays at the market after complete delivery.

Idea is to drop off some bananas between the plantation and the market.  Refrigeration is required to avoid bananas going bad!

Status (planatation, 250 mile point, 500 mile point, market)

First trip with 1000 bananas, stop at 250 miles, drop off 500 bananas, and come back to plantation.  (status:  2000, 500, 0, 0) camel ate 500 bananas.

Second trip with 1000 bananas, stop at 250 miles, pick up 250 (to make 1000), drop off 250 at 500 mile point, come back to plantation.  (Status: 1000, 250,250,0) Camel ate 1500 bananas.

Last trip with 1000 bananas, stop at 250 miles, fill-up 250 (total 1000), stop at 500 miles, fill-up to make total 1000.  Travel all the way to market with 500 left.

(Status: 0,0,0,500) Camel ate 500+1000+1000.

Net delivery: 500 bananas to market.

Using the camel to transport bananas across the desert, George loses all bananas to the camel's consumption before reaching the market, resulting in 0 bananas delivered.

The question asks how many bananas can George, the plantation owner, transport to the market across a 1000 mile stretch of desert using a camel that can carry 1000 bananas and eats one per mile. George has 3000 bananas to start with.

To maximize the number of bananas delivered, George must use a strategy that conserves bananas while accounting for the camel's consumption. For the first trip, George loads the camel with 1000 bananas, travels 333 miles (eating one banana per mile), deposits 667 bananas, and returns with 0. He repeats this until all bananas are 333 miles into the desert. This requires three round trips for the first third of the journey, resulting in the loss of 2000 bananas and leaving 1000 bananas 333 miles into the desert.

Next, he takes 1000 bananas, goes another 500 miles (leaving 500 bananas), and returns for the last batch of 500. This leaves him with 500 bananas 500 miles into the desert. Finally, he carries the last 500 bananas the remaining distance of 500 miles to the market, arriving with 0 bananas. Therefore, the greatest number of bananas George can deliver to the market is 0. This proves that it is impossible to deliver any bananas to the market under the given conditions.

Answer : b) 13/16

Given : t varies as v

So t = k v  where k is the constant of proportionality.

t = 2 4/7 when v =13/14. Using these values we find out k

[tex]t = 2\frac{4}{7} =\frac{18}{7}[/tex]

[tex]v =\frac{13}{14}[/tex]

t = k * v

[tex]\frac{18}{7}= k *\frac{13}{14}[/tex]

Multiply by 14/13 on both sides

[tex]\frac{18}{7} *\frac{14}{13} = k *\frac{13}{14}*\frac{14}{13}[/tex]

So  [tex]k =\frac{36}{13}[/tex]

We got the value of k. Now we find v when t = 2 1/4

[tex]t = 2\frac{1}{4} =\frac{9}{4}[/tex]

t = k * v

We know the value of t and k

[tex]\frac{9}{4}= \frac{36}{13}* v[/tex]

Multiply by 13/36 on both sides

[tex]\frac{9}{4} *\frac{13}{36} =\frac{36}{13}*\frac{13}{36}* v[/tex]

So  [tex] \frac{13}{16}= v[/tex]

Option B is correct

Isolate the x. Note the equal sign. What you do to one side, you do to the other.

First, subtract 2 from both sides

-x = 5/8 - 2

Make sure they have the same denominator. Remember that what you multiply to the denominator, you multiply the numerator:

-x = 5/8 - 16/8

-x  = - 11/8

Isolate the x. Divide -1 from both sides

(-x)/-1 = (-11/8)/-1

x = 11/8
