PLEASE HELP I NEED HELP ITS MULTIPLYING FRIACTIONS AND MIXED FRACTIONS

All answers are simplified

1) 4/5

2)2/7

3)11/24

4)25

5)10 1/12

6)3 31/48

Step-by-step explanation:

I simplified all of my answers

1) 8/2 x 9/10= 72/90= 4/5

2)3/7 x 2/3= 6/21= 2/7

3)1/2 x 11/12= 11/24

4) 4 x 6 1/4= 4/1 x 25/4= 100/4= 25/1= 25

5)3 2/3 x 2 3/4= 11/3 x 11/4= 121/12= 10 1/12

6) 7/8 x 4 1/6= 175/48= 3 31/48

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'.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
