Answer:
The equation for the speed of the train is: 162 = 3x
I think the speed of the train is 54 miles per hour
Step-by-step explanation:
We know that:
y = distance in miles
x = speed of train (miles/hour)
t = time traveled from the departing station (hours)
The equation: y = xt is given, we can therefore substitute the give values:
y = xt or tx
162 = 3x (This would be the equation)
Now we can find x by diving 3 on both sides of "="
162/3 = x
54 = x (This would be the speed of train)
Hope this helps!

correctly describe the slope of the graph of 2x + 5y = 6?
Answer:
[tex]2x + 5y = 6z[/tex]
ok
The slope of the graph of 2x + 5y = 6 is; -2/5.
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
The slope of the line y = mx + c is calculated as follows:
m = Δy/Δx
To find the slope of the line of 2x + 5y = 6
Therefore, the slope of the line is;
2x + 5y = 6
5y = 5 - 2x
Now divide by 5
y = 1 - 2/5x
When we simplify it, then we get;
m = -2/5
Hence, the slope of the graph of 2x + 5y = 6 is; -2/5.

Find the third side in simplest radical form
Answer:
x= 2[tex]\sqrt{6}[/tex]
Step-by-step explanation:
To solve this problem we first observe the Pythagoras equation. If a=x and b = 7 are the lengths of the legs of a right triangle and c= [tex]\sqrt{73}[/tex] is the length of the hypotenuse, then the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.
This relationship is represented by the formula:
a*a + b*b = c*c
[tex]x^{2}[/tex] + [tex]7^{2}[/tex] = [tex](\sqrt{73} )^2[/tex]
=> x= [tex]2\sqrt{6}[/tex]

you spin the spinner shown below once. each sector shown has an equal area. what is P(ladybug)
Answer:
1/5 or 20%
All sectors have an equal area, so that means that all have an equal chance of being landed on. There is only 1 sector containing a ladybug out of all 5 sectors. That means you have a 1 out of 5 chances of landing on the ladybug if you spin once.

Write an equation for the sine wave. What is the amplitude and period?
Answer:
Amplitude is the distance between the center line of the function and the top or bottom of the function, and the period is the distance between two peaks of the graph, or the distance it takes for the entire graph to repeat. Using this equation: Amplitude =APeriod =2πBHorizontal shift to the left =CVertical shift =D.

Chris is six years older than his sister Kennedy. The sum of their ages is 38. Write an equation to find Chris and Kennedy's ages. Make certain that you indicate what the variable represents.
Answer:16 , 22
Step-by-step explanation:
Given
Chris is six-year older than his sister
The sum of their ages is 38
Suppose the age of Chris sister is x
So Chris age is [tex]x+6[/tex]
the sum is
[tex]\Rightarrow x+x+6=38\\\Rightarrow 2x+6=38\\\Rightarrow 2x=32\\\Rightarrow x=16[/tex]
Chris age [tex]16+6=22\ \text{years}[/tex]
