Solve 8x − 2(x + 1) = 7x + 8. (5 points) 6 −6 −10 10

8x − 2(x + 1) = 7x + 8

8x-2x -2=7x+8

6x-2=7x+8

6x-7x-2=8

-x=8+2

-x= 10

X=10/-1

X= -10

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?

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.
