Answer:
Step-by-step explanation:
The given equation is
4x + 24x - 2 = 7(4x +2)
First step is to expand the parenthesis on the left hand side by multiplying each term inside the parenthesis by the term outside the parenthesis. It becomes
4x + 24x - 2 = 28x + 14
Collecting like terms such that the terms containing x will be on the lefthand side and constant terms will be on the right hand side, it becomes
28x - 28x = 14 + 2
0 = 16
0 cannot be equal to 16. Therefore, there is no solution.
The likely error of my friend was
28x - 28x = x

Answer: 350
Step-by-step explanation:
Explanation:
a = adult tickets
s = student tickets
║ a + s = 754
║s = a + 54
Plug s = a + 54 into a + s = 754
a + (a + 54) = 754
a + a + 54 = 754
2a + 54 = 754
2a = 754 - 54
2a = 700
a = 350
The answer Is 2/12 because if u multiply 1 x2 it is 2 then 3 x4 which is 12
Answer:
=22%
Step-by-step explanation:
Since we have given two conditions simultaneously that is windy and not sunny. So we will use the concept of conditional probability.
The probability of sunny day= P(sunny)=10%
P(sunny)=10%=0.1
The probability of windy and not sunny=P(windy|not sun)=20%
P(windy|not sun)=20% = 0.2
Now divide the both probabilities:
P(windy|not sun)/P(sunny)
=0.2/[1-0.1]
{Hence there are 10% chances of sun tomorrow than there are (1 - 0.1) chances of no sun}
If we subtract 1 from 0.1 than it becomes:
=0.2/0.9
=2/9
=0.2222222222
=22%
Hence the probability that it is windy = 22% ....
