Traffic lights at three different road crossing change after 48 seconds, 72 seconds, and 108 seconds respectively. At what time will they change together again if they change simultaneously at 7 A.M.?
Answer: 8:07:12
Find the Prime Factors.
48 = 2⁴ x 3
72 = 2³ x 3²
108 = 2² x 3³
Find the Least Common Multiple.
Two:
LCM = 2⁴ x 3³
LCM = 16 x 27 = 432
Convert 432 seconds to minutes.
432 seconds = 7 minutes, 12 seconds.
Hope this helps!
Answer:
7 minutes , 12s

A florida factory produces fishing reels at a rate of 800 per day, every day. IN April, they are forced to cut their production by 15due to an aluminum shortage. A chain of sporting goods stores orders 20,000 fishing reels. Will the factory be able to produce enough fishing reels in the 30 days of April to meet this order? Explain how you know.
Answer:
Yes
Step-by-step explanation:
Yes because if you subtract the 15 from 800 you get 785 you times that by 30. You get 23,550. I drop the 30, 1 by 1 and when I got to 26 it is 20,410. so yes they can in 25 and 1/2 days to be exact.

Solve the following system by substitution. 7x + 2y = 16 –21x – 6y = 24 What is the solution ?
Answer:
no solution
Step-by-step explanation:
x=(16-2y)/7
-21*(16-2y)/7-6y=24
-3(16-2y)-6y
-48+6y-6y=24
-48=24
you can't solve for the variables
There is no solution for given system of equations.
System of equations :The given equations are,
[tex]7x+2y=16\\\\x=\frac{16-2y}{7}[/tex]
Another equation is, [tex]-21x-6y=24[/tex]
Substitute value of x in above equation.
[tex]-21(\frac{16-2y}{7} )-6y=24\\\\-48+6y-6y=24\\\\-48\neq 24[/tex]
Thus, there is no solution for given system of equations.

Solve for x when 4x+x+2=10x−13
Answer:
x = 3
Step-by-step explanation:
First lets add 4x + x so that we can get one x value on that side of the equation.
4x + x + 2 = 10x - 13
5x + 2 = 10x - 13
Then we can solve for x from there
5x + 2 = 10x - 13
-5x + 2 = -13 [Subtract 10x from both sides of the equation]
-5x = -15 [Subtract 2 from both sides of the equation]
-x = -3 [Simplify]
x = 3 [Simplify]
Hope this helps! I apologize if I got this incorrect
Answer: x = 3
Steps: 4x + x + 2 = 10x - 13
Combine like terms: 5x + 2 = 10x - 13
Subtract 2 from both sides: 5x + 2 - 2 = 10x - 13 - 2
Simplify: 5x = 10x - 15
Subtract 10x from both sides: 5x - 10x = 10x - 15 - 10x
Simplify: -5x = -15
Divide both sides by -5: -5x ÷ -5 = -15 ÷ -5
Simplify: x = 3

three more than a certain number is 6 less than 4 times that same number. what is the number?
Answer: 3
Step-by-step explanation:
Let x = the number
x + 3 = 4x - 6
-3x = -9
x = 3
The number that's represented by the information given will be 3.
Let the number be represented by x.
Since three more than a certain number is 6 less than 4 times that same number, then the number will be calculated thus:
x + 3 = (4 × x) - 6
x + 3 = 4x - 6
Collect like terms
4x - x = 3 + 6
3x = 9
x = 9/3
x = 3
Therefore, the value of the number will be 3.

Miguel has $30. He spends $6.75 on a movie ticket, $3.65 for snacks, and $2.00 for bus fare each way.
How much money does Miguel have left? please help :}
Answer:
$15.60
Step-by-step explanation:
We can solve this problem easily by adding up Miguel's expenses, and then subtracting them from the amount he started with. Be careful, as he pays $4, not $2, in total for bus fare, because he is paying $2 to and from:
[tex]6.75+3.65+4.00[/tex]
[tex]=14.40[/tex]
Let's subtract our sum, [tex]14.40[/tex], from our total, [tex]30[/tex]:
[tex]30-14.40[/tex]
[tex]=15.60[/tex]
Miguel has $15.60 left.

Answer:
The correct answer is B: ∠DGB is supplementary to ∠CGB. I got it right on my test.
Step-by-step explanation:
From the diagram option (B) ∠DGB is supplementary to ∠CGB can be proven true
What is Supplementary angle?Two angles or arcs whose sum is 180 degrees.
From the given figure we can say that
∠DGB is supplementary to ∠CGB
Because ∠DGB + ∠CGB = 180 degree
Angles on a straight line add up to 180 degrees
All other options are false
Hence, Option (B) ∠DGB is supplementary to ∠CGB can be proven true
