You also have to explain how you got your answer. I will give brainliest.

7= 2 4/5         8=2/21           9= 6 3/7          10= 1/6            11= 7/5           12=77/90

Step-by-step explanation:

3 1/5= 16/5-2/5=14/5 which equals to the same thing to 2 4/5

5/3= 35/21

11/7= 33/21

35/21-33/21= 2/21

3 3/4=15/4 times 12/7 straight ahead which is 180/28 equals to the same thing as 45/7 = 6 3/7

1/5 times 7/1 so u flip it over as u can see which is 7/5

2 1/5= 11/5    2 4/7= 18/7       11/5 times 7/18=77/90

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
