The two trains travel for the same amount of time, but because their speeds are different, they travel different distances. The two distances add to 450 miles.
distance = speed * time
For the commuter train, you have distance d1, time t, and speed s.
For the express train, you have distance d2, time t, and speed s + 25.
The time is 6 hours, so,
For the commuter train, you have distance d1, time 6, and speed s.
For the express train, you have distance d2, time 6, and speed s + 25.
d = st
Commuter:
d1 = st
Express
d2 = (s + 25)t
Add the equations:
d1 + d2 = st + (s + 25) t
d1 + d2 = st + st + 25t
d1 + d2 = 2st + 25t
d1 + d2 = (2s + 25)t
The two distances add to 450 miles, d1 + d2 = 450, and t = 6.
450 = (2s + 25)(6)
75 = 2s + 25
50 = 2s
s = 25
The commuter train's speed is 25 mph.
The express train's speed is 50 mph.
Check:
distance = speed * time
In 6 hours, the commuter train travels d = 25 mph * 6 hours = 150 miles.
In 6 hours, the express train travels 50 mph * 6 hours = 300 miles.
150 miles + 300 miles = 450 miles.
The distances do add to 450 miles and the speed of the express train is 25 mph faster, so our answer is correct.

how can you use the properties of real numbers to simplify algebraic expressions
Answers
[tex](x+4)(x+7)[/tex]
The first property we'll apply is the distributive property, which states in its simplest case that, given three real numbers a, b, and c:
a(b + c) = ab + ac
If x is a real number, then we know that (x + 4) must be a real number too, since the sum of any two real numbers is itself a real number. We can treat this (x + 4) term the same way we treat that number a, and distribute it to the x and the 7, obtaining:
[tex](x+4)(x+7)=(x+4)x+(x+4)7[/tex]
In the next step, we'll reuse the distributive property to further expand our expression, but we have to take note of a subtle detail first:
We originally defined the distributive property with the expression a(b+c); years of experience with the properties of multiplication might have conditioned you to view that expression as equivalent to (b+c)a, but that fact rests upon the application of another property: the commutative property of multiplication, which states in its simplest case that, for any two numbers a and b, ab = ba. a(b+c) and (b+c)a might not be totally equivalent statements, but they have equivalent values. Returning to the problem, we can use the distributive property and the commutative property to expand our expression:
[tex](x+4)x+(x+4)7=(x^2+4x)+(7x+28)[/tex]
From here, we can use the associative property of addition to regroup our terms, allowing us to combine the 4x and the 7x in our next step. In case you forgot, the associative property, in its simplest form, states that, for any three numbers a, b, and c:
(a + b) + c = a + (b + c)
This is what allows us to write expressions like a + b + c without parentheses; the associative property tells us that the order we add the numbers up isn't important.
Regrouping the terms in our expression, we get:
[tex](x^2+4x)+(7x+28)=\big(x^2+(4x+7x)\big)+28[/tex]
To combine the 4x and 7x terms, we again use the distributive property. Note that, by the commutative property of multiplication, the equation
a(b + c) = ab + ac
is equivalent to
(b+c)a = ba + ca
Here, our a is x, and our b and c are 4 and 7. Which means that:
[tex]4x + 7x = (4+7)x=11x[/tex]
Finally, we have our simplified expression:
[tex]x^2+11x+28[/tex]
Seeing the properties applied step-by-step in this way really gives you an appreciation for how foundational they are to algebra!

1. List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).
Length:

Answers
Answer:
Length
Step-by-step explanation:
mhm
1) The dimensions of the rectangular prism or box which I found are:
Length: 6 inchesWidth: 2.5 inchesHeight: 12 inches (1 foot)2) The shape of the cross-section when the box is cut parallel to the base will be a rectangle.
3) Surface Area of the box is234 in²
4) Surface Area of the box if scaled up by a factor of 10 is 23,400 in²
5) Volume of the box: 180 in³
6) Volume of the box if scaled down by a factor of 1/10 is 0.18 in³
Given:
Dimensions of the box to be:
Length: 6 inches
Width: 2.5 inches
Height: 12 inches (1 foot)
1) The shape of the cross-section when the box is cut parallel to the base will be a rectangle.
2) To calculate the surface area of the box:
Surface Area = 2*(Length*Width + Length*Height + Width*Height)
Surface Area = 2*(6*2.5 + 6*12 + 2.5*12)
Surface Area = 2*(15 + 72 + 30)
Surface Area = 2*(117)
Surface Area = 234 in²
3) If the box is scaled up by a factor of 10, the new dimensions would be:
Length: 6 inches * 10 = 60 inches
Width: 2.5 inches * 10 = 25 inches
Height: 12 inches * 10 = 120 inches
To find the new surface area:
New Surface Area = 2*(60*25 + 60*120 + 25*120)
New Surface Area = 2*(1500 + 7200 + 3000)
New Surface Area = 2*(11700)
New Surface Area = 23,400 in²
4) The volume of the box:
Volume = Length * Width * Height
Volume = 6 * 2.5 * 12
Volume = 180 in³
5) If the box is scaled down by a factor of 1/10, the new dimensions would be:
Length: 6 inches * 0.1 = 0.6 inches
Width: 2.5 inches * 0.1 = 0.25 inches
Height: 12 inches * 0.1 = 1.2 inches
To find the new volume:
New Volume = Length * Width * Height
New Volume = 0.6 * 0.25 * 1.2
New Volume = 0.18 in³

A line-marking machine lays down lime powder to mark two equal foul lines on a playing field. If each line for this field measures 311 feet, how many feet of lime powder will be deposited?
Answers
2 lines * (311feet/lines)= 622 feet.
The machine will deposit 622 feet of lime powder to mark both foul lines on the playing field.
To solve this problem, we need to consider that the line-marking machine is laying down lime powder to mark two equal foul lines on a playing field. Each foul line measures 311 feet.
Since there are two lines of equal length, we simply need to add the lengths of these two lines together to find the total amount of lime powder deposited.
Here is the calculation:
Length of one foul line = 311 feet
Number of foul lines = 2
Total length of lime powder deposited = Length of one foul line [tex]\times[/tex] Number of foul lines
Total length of lime powder deposited = 311 feet [tex]\times[/tex] 2
Total length of lime powder deposited = 622 feet.

2y+7x=4;x=5,10,15 PLEASE HELP ASAP!!!!

Final answer:
To solve the equation 2y+7x=4 for x=5, x=10, and x=15, substitute each value into the equation and solve for y to get y=-15.5, y=-33, and y=-50.5 respectively. It’s important to check the solutions by substituting them back into the original equation.
Explanation:
To solve the given linear equation 2y+7x=4 for different values of x (x=5, x=10, x=15), we need to substitute these values of x into the equation and solve for y. Here’s how it can be done:
For x=5: 2y + 7(5) = 4.2y + 35 = 4.
2y = 4 - 35.
2y = -31.
y = -31/2.
y = -15.5.For x=10: 2y + 7(10) = 4.
2y + 70 = 4.
2y = 4 - 70.
2y = -66.
y = -66/2.
y = -33.For x=15: 2y + 7(15) = 4.
2y + 105 = 4.
2y = 4 - 105.
2y = -101.
y = -101/2.
y = -50.5.

Mari has a part time job. She earns $7 an hour. She makes at most $143.50 a week. What is the greatest number of hours that she works?
Answers
Mari works at most 20 hours per week.
Explanation:To find the greatest number of hours that Mari works, we can divide her total weekly earnings by her hourly wage. In this case, we divide $143.50 by $7. The result is approximately 20.5. Since Mari cannot work a fraction of an hour, we round down to the nearest whole number. Therefore, the greatest number of hours she works is 20 hours.
