The time that taken for the two trains is 1.2 hours.
The computation of the time taken for the two trains is shown below:
Given that
The westbound train travels 55 miles per hour.
And, the eastbound train travels 75 miles per hour.
So, the total speed is
= 55 miles per hour + 75 miles per hour
= 130 miles per hour
The distance is 156 miles
So, the time taken is
[tex]= \frac{distance}{speed}\\\\= \frac{156\ miles}{130\ miles\ per\ hour}\\\\[/tex]
= 1.2 hours
Therefore we can conclude that the time that taken for the two trains is 1.2 hours.

Answer:
1.2 hours
Step-by-step explanation:
Given data:
Speed of the westbound train = [tex]55 miles/hr[/tex]
Speed of the eastbound train = [tex]75 miles/hr[/tex]
Since the trains are moving in the opposite direction their relative speed becomes,
[tex]55 miles/hr +75 miles/hr=130 miles/hr[/tex].
Since, time = distance / speed
Now the time taken for the two trains to be 156 miles apart
[tex]time = \frac{156 miles}{130 miles/hr} \\=1.2 hours[/tex]
Hence, the time taken for the two trains to be 156 miles apart = [tex]1.2 hours[/tex]

Line LR bisects MN at point L. Find the length of ML if MN = 152 ft.
Answer:
[tex]ML = 76\text{ feet}[/tex]
Step-by-step explanation:
Since Line LR bisects MN at point L, by the definition of bisector:
[tex]\overline{ML} \cong \overline{LN}[/tex]
We want to determine ML if MN measures 152 feet.
MN is the sum of ML and LN. Hence;
[tex]ML + LN = MN[/tex]
Since ML = LN and MN = 152:
[tex]ML + (ML) = (152)[/tex]
Simplify:
[tex]2ML = 152[/tex]
And divide. Therefore:
[tex]ML = 76\text{ feet}[/tex]
In conclusion, ML measures 76 feet.

Write the following statement in equation form using variables x and y. "Sum of two numbers is 15 and difference is 11.
Answer:
see explanation
Step-by-step explanation:
Using x and y to represent the 2 numbers with x > y , then
x + y = 15 → (1)
x - y = 11 → (2)
Adding the 2 equations term by term to eliminate y
2x = 26 ( divide both sides by 2 )
x = 13
Substitute x = 13 into (1)
13 + y = 15 ( subtract 13 from both sides )
y = 2
The 2 numbers are 13 and 2

Answer:
First, just to recap, the angle that has a measure of 60 and the angle that has a measure of 2x+14 are vertical angles.
This means, that they are equal to each other.
Knowing this, the rest is pretty easy. We just set up an equation:
60 = 2x+14
And solve for x: (I'm going to speed through, but let me know if you need me to go step by step...)
2x = 46
x = 23

The equations y=x22−8 and y=2x−2 are graphed below. What are the solutions to the equation x22−8=2x−2?
A
x=−8 and x=−2
B
x=−6 and x=10
C
x=−4 and x=4
D
x=−2 and x=6
Answer:
x= -2 and x = 6
Step-by-step explanation:
The solutions are where the two graphs intersect
x=6, y= 10 is one point
x=-2 and y = -6 is the other point
The intersection points of both the equations are the solutions
From the graph the points are
(6,10)(-2,-6)Hence
x=-2 and x=6 are the solutions

On a recent math test, Samantha scored 3 points for each of the 18 multiple choice questions she
answered correctly and 5 points for each of the 6 short response questions she answered
correctly.
She scored an additional 4 points for the bonus question. Write an expression for her total score on
the test and then find her score.
The required expression will therefore be:
(3×18) + (5×6) + 4
Her total score is 88points :
From the question given, we are told that Samantha scored 3 points for each of 18 multiple choice questions, this means that the total points made here is expressed as:
(3 × 18) ...1
If she got 5 points for each of the 6 short response questions she answered
correctly, the total point made will be expressed as;
(5×6) ... 2
Total score for an additional 4 points for the bonus question will be "4"
Expression for her total score will be the sum of all the expression above as thus:
(3×18) + (5×6) + 4
Taking the sum, her score will be:
= (3×18) + (5×6) + 4
= 54 + 30 + 4
= 84 + 4
= 88 points
The required expression will therefore be:
(3×18) + (5×6) + 4
Her total score is 88points

A wall in Marcus's bedroom is 8 2/5 feet high and 16 2/3 feet long. If he paints 1/2 the wall blue, how many square feet will be blue?
Answer:
70 ft^2
Step-by-step explanation:
Find the area of the wall
A = l*w where l is the length and w is the width
A = 8 2/5 * 16 2/3
Change to improper fractions
A = 42/5 *50/3
Rewriting
A = 42/3 * 50/5
= 14 * 10
A = 140 ft^2
He paints 1/2
1/2 (140) = 70 ft^2
