Answer:

The equation has Zero solution.

Step-by-step explanation:

Consider the provided equation.

$6x+15=6(x+3)$

Apply the distributive property: $a(b+c)=ab+ac$

$6x+15=6x+18$

Now isolate the variables by subtracting 6 from both the sides.

$6x+15-6x=6x+18-6x$

$15=18$

Which is not true.

Hence, the equation has no solution or the equation has Zero solution.

6x + 15 = 6 (x + 3)

6x + 15 = 6x + 18

6x = 6x + 3

0 = 3

So, there are no solutions to this equation.

In a class of 26 students, 15 of them like maths, 13 of them like English and 9 of them don't like Maths or English. Find the pr

galben [10]

Answer: 0 0769

Step-by-step explanation:

Let x be the number of students that offer both subjects

15 - x + x + 13 - x + 9 = 26

-x + 37 = 26

-x = -11

x = 11

Number of student that offer english but not math = 13 - 11 = 2

The probability of english but not math = 2/26 = 0.0769

Answer:

0.3571 or 35.14%

Step-by-step explanation:

There are 15 children in total in the class at first. Of those children, 5 are second graders and 10 are not.

If the first chosen children was not a second grader, there are 5 second graders among the 14 children left. The probability of selecting a second grade child is:

$P = \frac{5}{14}\\P=0.3571\\P=35.71\%$
