Answer:
The time it will take will be ;
t = (2x -6)/(x^2-6x)
Where x is the amount of time
in minutes taken by the technician who is slower
Step-by-step explanation:
We want to write the time it would take to run the tests if the technicians work together.
Let the time taken by the first technician be x minutes
The time that would. taken by the second is 6 minutes less which is (x -6) minutes
So if they work together, how long will it take?
That would be ;
t = 1/x + 1/(x-6)
t = (x + x -6)/(x(x-6))
t = (2x -6)/(x^2 -6x)
The time it will take if they both work together is ;
t = (2x -6)/(x^2-6x)
where x minutes is the amount of time taken by the technician who is slower of the two

Problem-solving Ava and Ben set the alarms on their phones to sound at 6:30 am
Both alarms sound together at 6:30 am.
Ava's alarm then sounds every 24 minutes.
Ben's alarm then sounds every 30 minutes.
Use the lowest common multiple to find out when both alarms next sound
together.
Answer:
08:30 am
Step-by-step explanation:
30 * 1 =30 24 * 1 = 24
30* 2 = 60 24 * 2 = 48
30 * 3 = 90 24 * 3 = 72
30 * 4 = 120 24 * 4 = 96
24 * 5 = 120
The lowest common multiple ist 120.
06:30 am + 120 min = 08:30 am

-5 ( x + 7) = -5x + 35
Step-by-step explanation:
Let's solve your equation step-by-step.
−5(x+7)=−5x+35
Step 1: Simplify both sides of the equation.
−5(x+7)=−5x+35
(−5)(x)+(−5)(7)=−5x+35(Distribute)
−5x+−35=−5x+35
−5x−35=−5x+35
Step 2: Add 5x to both sides.
−5x−35+5x=−5x+35+5x
−35=35
Step 3: Add 35 to both sides.
−35+35=35+35
0=70
Answer:
There are no solutions.
Answer:
x= no solution
Step-by-step explanation:
-5(x+7)=-5x+35
-5x-35=-5x+35

What is the equation of the line that passes through the point (-8, 3) and has a
slope of -1/4
Answer:
-1/4x + 1 ( If this is wrong then ignore this)
Step-by-step explanation:
The formula for a problem like this is y - y1 = m(x - x1). The x coordinate, -8 is the x1 and the y coordinate 3 is x1. So the equation is y - 3 = -1/4(x + 8)
Equation:
y - 3 = -1/4(x + 8)
y - 3= -1/4x - 2
y = -1/4x + 1
Therefore the equation for the line is y = -1/4x + 1
Given parameters:
Slope of the line = [tex]-\frac{1}{4}[/tex]
Coordinates of the points = (-8, 3)
Unknown:
Equation of the line = ?
Solution:
To find the equation of the line, we must note that any straight line can be represented by the equation;
y = mx + c
where x and y are the coordinates
m is the slope
c is the y-intercept of the line
Input the parameters and solve for c;
x = -8 and y = 3;
3 = [tex]-\frac{1}{4}[/tex] x (-8) + c
3 = 2 + c
c = 1;
So the equation of the line is ;
y = [tex]-\frac{1}{4}[/tex]x + 1
multiply through by 4;
4y = -x + 4
The equation of the line is 4y = -x + 4

To determine whether they used the same number of tiles, set the two expressions equal to each other and solve for x. Is there a solution for x? Why or why not? If there is a solution, what is it?
Here is the equation stuff to solve:
Expression for the number of tiles Bruce used : 5x+2
Expression for the number of tiles Felicia used : 5x + 5
How could you change the equation so it has infinitely many solutions? What would infinitely many solutions mean in terms of the situation?
To determine whether they used the same number of tiles, set the two expressions equal to each other and solve for x. Is there a solution for x? Why or why not? If there is a solution, what is it?
5x +2 = 5x + 5 (subtract 5x and 2 on both sides)
0 = 3 No solution
How could you change the equation so it has infinitely many solutions?
Have 2 or 5 change because they need to be equal to each other. Its fine what you put as long as the equal sign is the same as the other side like 3 = 3 for example or 5 = 5, something like that. Once they have the same end then you can substitute the number to x.
What would infinitely many solutions mean in terms of the situation?
x represents the number of tiles they used

3/8 divided by 2/5??
Answer:
15/16
Ste
Step-by-step explanation:
Keep, Change, Flip.
(1) Keep the first fraction, 3/8.
(2) Change the sign from a division sign to a multiplication sign.
(3) Flip the last fraction, 2/5 --> 5/2.
(4) Multiply across.
3/8 x 5/2= 15/16
The 3/8 divided by 2/5 is equal to 15/16.
To divide fractions, multiply the first fraction by the reciprocal of the second fraction.
To divide 3/8 by 2/5:
(3/8) ÷ (2/5) = (3/8) × (5/2)
Now, let's multiply the numerators and denominators:
(3 × 5) / (8 × 2) = 15/16
