Which of the following describes the correct process for solving the equation 2x + 6 = 22 and arrives at the correct solution? O Subtract 6 from both sides, and then divide by 2. The solution is x = 8.
O Divide both sides by 6, and then add 2. The solution is x = 8.
Add 6 to both sides of the equation, and then divide by 2. The solution is x = 6
Subtract 6 from both sides of the equation, and then divide by 22. The solution is x =

Subtract 6 from both sides, and then divide by 2. The solution is x = 8.

Step-by-step explanation:

2x + 6 = 22

Subtract 6 from both sides:

Divide by 2 on both sides:

The solution is x = 8.

Hope this helps.

it has the same slope and a different y-intercept

hope this : )

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
