Solve 2(3x+6)=3(x-9) 2p-3=3p+2 2(3x-1)-7(5x+4)=9(2x-3)

earnstyle [38]

Answer:

Step-by-step explanation:

1. 6x + 12 = 3x - 27

3x + 12 = -27

3x = -39

x = -13

2. 2p - 3 = 3p + 2

-p - 3 = 2

-p = 5

p = -5

3. 6x - 2 - 35x -28 = 18x - 27

-29x - 30 = 18x - 27

-47x - 30 = -27

-47x = 3

x = -3/47

Find the value of x so that the polygons have the same perimeter

mestny [16]

x - 2 + x + 4 + x - 2 + 4 - 4 = x + 3 + x + 4 + x + 5

There are 42 students 21 are in 7th grade 14 are in 8th 7 are in ninth whats the probability of an eighth grader winning

Varvara68 [4.7K]

Answer:

The probability of an eighth grader winning is 1/3

Step-by-step explanation:

Total no. of students = 42

Number of students in 7th grade = 21

Number of students in 8th grade = 14

Number of students in 9th grade = 7

Probability of event = $\frac{\text{Favorable outcomes}}{\text{Total outcomes}}$

So,the probability of an eighth grader winning= $\frac{14}{42}=\frac{2}{6}=\frac{1}{3}$

Hence The probability of an eighth grader winning is 1/3
