5x + 1 = 6x - x
I need help on this problem may you help
Answers
Answer:
Step 1: Simplify both sides of the equation.
5x+1=6x−x
5x+1=6x+−x
5x+1=(6x+−x)(Combine Like Terms)
5x+1=5x
5x+1=5x
Step 2: Subtract 5x from both sides.
5x+1−5x=5x−5x
1=0
Step 3: Subtract 1 from both sides.
1−1=0−1
0=−1
Answer:
There are no solutions.
Step-by-step explanation:
Answer:
no solution
Step-by-step explanation:
Given
5x + 1 = 6x - x , that is
5x + 1 = 5x ( subtract 1 from both sides )
5x = 5x - 1 ( subtract 5x from both sides )
0 = - 1 ← not possible
This indicates the equation has no solution

Josh was packing to move to another office. He packed 3 2/5 boxes on Tuesday and 2 9/10 boxes on Wednesday. After everything was moved to his new office on Wednesday afternoon, he only found 4 1/4 boxes. How many boxes were missing?
Answers
Answer:
2 1/10 boxes were missing.
Step-by-step explanation:
It is given that,
Josh packed [tex]3\dfrac{2}{5}[/tex] boxes on Tuesday
Josh packed [tex]2\dfrac{9}{10}[/tex] boxes on Wednesday
After everything was moved to his new office on Wednesday afternoon, he only found [tex]4\dfrac{1}{4}[/tex] boxes.
We need to find the no of boxes that are missing.
Total no of boxes packed on Tuesday and Wednesday,
[tex]3\dfrac{2}{5}+2\dfrac{9}{10}\\\\=\dfrac{17}{5}+\dfrac{29}{10}\\\\=\dfrac{63}{10}[/tex]
Missing boxes :
[tex]M=\dfrac{17}{4}-\dfrac{63}{10}\\\\=\dfrac{41}{20}\\\\=2\dfrac{1}{20}[/tex]
Hence, 2 1/10 boxes were missing.

Which of the following is the value of PQ?
A) 46
B) 61

D) 67
Answers

Step-by-step explanation:
Answer:
B) 61Step-by-step explanation:
QR = QS
3x + 16 = 7x - 24
16 + 24 = 7x - 3x
40 = 4x
x = 40/4
x = 10
substitute x=10 into PQ = 2x+41
PQ = 2(10) + 41
PQ = 20 + 41
PQ = 61
A recent survey suggests that 47% of all televisions are connected to the internet, 32% are voice controlled, and 22% are both connected to the internet and voice controlled. Suppose a television is selected at random and it is voice controlled. What is the probability that a randomly selected voice-controlled television is also connected to the internet?
A. 0.15
B. 0.47
C. 0.69
D. 0.79
Answers
Answer:
0.69
Step-by-step explanation:
Here, we want to find the probability that a randomly selected television is connected to the internet given that it is voice-controlled
let P(V) is the probability of selecting a voice controlled television
P(I) is the probability that a selected television is connected to the internet
So the probability we want to calculate according to Baye’s theorem will be;
P(I|V) = P(I n V)/P(V)
P( I n V) = 22%
P(V) = 32%
So the probability is;
22%/32% = 0.6875 which is approximately 0.69
Answer: 0.69

The value of y is directly proportional to the value of x. If y = 24 when x = 6, what is the value of y when x = 48?
Answers
Answer:
192
Step-by-step explanation:
We know that x is 1/4 of y, since 6 is 1/4 of 24. Therefore, we can multiply 48 by 4 to get 192!
