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.?
Answers
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.

What is the probability of spinning a C?
Answers
Answer: 37.5%
Step-by-step explanation: Since there are 3 spaces for C it would be 3/8 for the amount of C's in all of the letters.

The probability of spinning C will be 3/8 or 0375.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
The spinner has eight equal section. And the 8 sections are marked as A, B, B, B, A, C, C, and C.
Then the total number of the event will be
Total event = 8 {A, B, B, B, A, C, C, C.}
Then the probability of spinning C will be
The favorable event will be
Favorable event = 3 {C, C, C}
P = 3 / 8
P = 0.375
The probability of spinning C will be 3/8 or 0375.

x ÷ 4 + 5= 8 I need someone to do it and double check for me please.
Answers
= x/4 + 5 = 8
= x/4 = 8 - 5 ( transposing +5 from LHS to RHS changes +5 to -5 )
= x/4 = 3
= x = 3 × 4 ( transposing ÷4 from LHS to RHS changes ÷4 to ×4 l
= x = 12
Let us see whether the value of x is correct or not by placing 12 in the place of x .
= 12 ÷ 4 + 5 = 8
= 3 + 5 = 8
= 8 = 8
= LHS = RHS
Which means the value of x we found out is correct .
Therefore , x = 12 .Step-by-step explanation:
[tex] \frac{x}{4} + 5 = 8 \\ x + 5 = 32 \ \\ x = 32 - 5 \\ x27[/tex]

C. x= 2
O D. x= 6
SUBMI
Answers
Answer:
Think
Step-by-step explanation:
4x - 6 + 2x = 18
You are solving for x so obviously you have to have your x variable on one side of the equal sign by itself.
So how do you do that? Combine the same calues together and seperate the rest
4x + 2x = 6x
6x = 18 + 6
6x = 24
x = 3
Practice practice practice. Simple stuff. You got this!
Answer:
A. x = 4
Step-by-step explanation:
To answer this question, we first have to combine like terms:
4x - 6 + 2x = 18
6x - 6 = 18
Now, we take away 6 from the left side and add it to the right side:
6x - 6 = 18
+6 +6
6x = 24
Then, we isolate the variable:
6x = 24
/6 /6
x = 4
Hope this helps :)
