It takes 17 seconds for a train to pass a 206-meter long bridge at normal speed. It takes 45 seconds for the same train to pass 170-meter long bridge at one-third of the normal speed. What is the length of the train in meters?
Answers
Answer:hello
Step-by-step explanation:sync bien
- L = length of the train in meters
- v = speed of the train in meters per second (normal speed)
- t1 = time taken by the train to pass the 206-meter long bridge at normal speed
- t2 = time taken by the train to pass the 170-meter long bridge at one-third of the normal speed
From the problem statement, we have two equations involving these variables:
Equation 1: L + 206 = v * t1
Equation 2: L + 170 = (1/3)*v * t2
We can solve this system of equations for L by eliminating v. To do this, we can rearrange Equation 1 to solve for v:
v = (L + 206) / t1
Then, we can substitute this expression for v into Equation 2:
L + 170 = (1/3)*[(L + 206) / t1] * t2
Multiplying both sides by 3*t1 and simplifying, we get:
3*L*t1 + 3*170*t1 = (L + 206)*t2
Expanding the right-hand side and simplifying, we get:
3*L*t1 + 510 = L*t2 + 206*t2
Now, we can solve for L by rearranging terms and simplifying:
L = (206*t2 - 3*170*t1) / (3*t1 - t2)
Substituting the given values, we get:
L = (206*45 - 3*170*17) / (3*17 - 45) = 510
The length of the train is 510 meters.

Answer:
There are 55 large boxes
and 70 small boxes.
Step-by-step explanation:
Let's assume that the number of large boxes is x, and the number of small boxes is y. We then can use how many pounds each box weighs to form a system of equations.
System:
\(50x+25y=4500\\x+y=125\)
Step 1: Solve for a variable
\(x+y=125\) is also \(y=-x+125\)
Step 2: Substitute
\(50x+25(-x+125)=4500\)
Step 3: Simplify
\(50x+-25x+3125=4500\\25x=1375\\x=55\)
Step 4: Solve for y
\(y=-55+125\\y=70\)

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

3/4 w=6 solve for w
Bc.
Answers
To solve for w, you need to isolate the variable on one side of the equation.
The equation is 3/4 w = 6.
To isolate w, you need to divide both sides of the equation by 3/4.
3/4 w / 3/4 = 6 / 3/4
The left side simplifies to w, because the 3/4 on the left side cancel out.
w = 6 / 3/4
To divide by a fraction, you need to multiply by its reciprocal.
w = 6 * 4/3
The right side simplifies to 8.
w = 8
Therefore, w = 8.

James buys 4 pens for $3. Which three points lie on the line that best represents the total cost, y, of x pens?
Which order pair is NOT on the line that best represents this relationship?
Responses (8,6) (4,3) (0,0) (6,8)
Answers
James buys 4 pens for $3, so each pen costs $3/4. The total cost of x pens is $3x/4.
The points (0,0), (4,3), and (8,6) all lie on the line y = $3x/4. The point (6,8) does not lie on this line.
Therefore, the answer is (6,8).

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.
