Answer:

x=3

Step-by-step explanation:

1) 3(x+7)=6(x+2)

2)Multiply the number on the outside by the numbers on the inside

3x+21 =6x+12

3)Subtract 3x from 6x. When you do that it cancels out itself on the side it came from leaving you with only 21 one that side.

21=3x+12

4)Subtract 12 from 21. When you do that it cancels out itself on the side it came from leaving you with only 3x on that side.

9=3x

5) Divide 3x from both sides that will cancel out the x leaving you with only 1x and it will turn the 9 into 3.

9/3x=3x/3x

x=3

Answer:The answer is $\frac{7}{18}$ and the number in green box =7

Step-by-step explanation:

P(Sophomore| Girl)=?

We have P(A | B) =P(A∩B)/ P(B)

P(Sophomore∩Girls)= $\frac{7}{30}$

Total Students =8+12+5+5 =30

Total girls =4+7+3+4 =18

P(Girls)= $\frac{18}{30}$

P(Sophomore | Girl)=P(Sophomore | Girls)/P(Girls)

= $\frac{7}{30\frac{18}{30} }$

= $\frac{7}{18}$

The number in green box =7

Answer:

it is 114

Step-by-step explanation:

you do distributive property and since there’s no number it counts as a 1 so then you had 8+5 and you get 13 then you times that by 9 then subtract that answer with 3.
