Charlie and Violet met for lunch at a restaurant between their two locations (exactly in the middle). It took
Charlie 2.6 hours to get there, but it only took Violet two hours because she was driving 15 mph faster than
Charlie. The distance between the two of them initially was 260 miles. Find the speed of the two drivers.
Charlie
Violet
mph
mph
Answer:
Charlie 55 miles per hour
Violet 65 miles per hour
Step-by-step explanation:
Charlie and Violet met for lunch at a restaurant between Memphis and New Orleans. Since, Charlie left Memphis and drove towards New Orleans, and Violet left New Orleans and drove towards Memphis, the total distance that they covered altogether is the total distance between Memphis and New Orleans.
It is given that the distance between Memphis and New Orleans is 394 miles. This means, the total distance both covered = 394 miles
Charlie drove for 4.8 hours and Violet drove for 2 hours. Let the speed of Charlie be x miles per hour. Since, the speed of Violet was 10 miles per hour faster than Charlies, the speed of charlie was (x + 10) miles per hour
Since, distance = speed multiplied by time
Distance covered by Charlie = 4.8x
Distance covered by Violet = 2(x + 10)
Altogether they covered 394 miles,
So,
394 = Distance covered by Charlie + Distance covered by Violet
394 = 4.8x + 2(x + 10)
394 = 4.8x + 2x + 20
374 = 6.8x
x = 55
Since, x represents the speed of Charlie, the speed of charlie was 55 miles per hour and speed of Violet was 65 miles per hour

Two trains, Train A and Train B, weigh a total of 150 tons. Train A is heavier than train B. The difference of their weights is 100 tons. What is the weight of each train?
Answer:
train b.
Step-by-step explanation:
becus of the 150 tons and 100 tons
Answer:
Train A: 125 tons
Train B: 25 tons
Step-by-step explanation:
We can write the situation as a+b=150, and we can also write the value for train b as a-100=b.
To make the equations have only one variable, we can use the substitution method to create a+(a-100)=100. In this, since we know what b equals, we were able to replace the b in the first equation with the value of b in the second equation. Next, we solve the problem for a.
a+(a-100)=150
a+a-100=150
2a-100=150
+100=+100
2a=250
250/2=125
a=125
Now that we know that train A is 125 tons, we can plug 125 in the equation that represents the weight of train B. Train B is 100 tons lighter than train A, and the equation for train b is a-100=b. We can replace a with 125, creating 125-100=b.
Solve.
125-100=b
25=b
Check answers.
a+b=150
a=125
b=25
125+25=150
150=150
The answers are equal!! So, this means train B is 25 tons, and train A is 125.
Hope this helps!

The determinant of the provided matrix is -7 after opening the matrix option (B) -7 is correct.
What is the matrix?It is defined as the group of numerical data, functions, and complex numbers in a specific way such that the representation array looks like a square, rectangle shape.
It is given that a matrix:
[tex]\rm H = \left[\begin{array}{ccc}0&2&3\\-1&3&5\\6&3&-2\end{array}\right][/tex]
As we know, the determinant in arithmetic is a real number that is a variable of the rows and columns of a square matrix. It lets specifying a few aspects of the matrix and the linear map that the matrix provides.
Open the above matrix to find the determinant:
|H| = 0[(-6 - 15)] - (-1)[-4 - 9] + 6[10 - 9]
|H| = 0[-21] - (-1)[-13] + 6[1]
|H| = 0 - 13 + 6
|H| = -7
Thus, the determinant of the provided matrix is -7 after opening the matrix option (B) -7 is correct.

What is the value of x
Answer:
x = 15

Move 11 to the other side, with "16" after the equal sign.
We need to subtract: 16-11 = 5
x/3 = 5
x = 5 x 3
x = 15

To double check...
15/3 + 11 = 16
5 + 11 = 16

Answer:
15
Step-by-step explanation:
First you take all of the non-variables on to the other side of the equal sign. It then turns out to be SUPER easy. x/3 = 16 - 11
x/3 = 5
x = 5*3
x = 15
