Please help me with all the 5 questions?

i will give you the "brainliest" if it is correct

B and D

Step-by-step explanation:

A: (5/6) x 13  =  0.883 x 13  =  10.833 which is less than 13

> B: 4 x 13  =  52 which is greater than 13

C: (3/4) x 13  =  .75 x 13  =  9.75 which is less than 13

> D: (10/10) x 13  =  1 x 13  =  13 which is equal to 13

2. A and C

3. D

4. D

5. A

1. B and D

2. A and C

3. 1/2 x 2,175

4. 54,811 x 2/4

5. Beth sold half the copies Rodney sold.

Step-by-step explanation:

1. 10/10 is the same as 1 so the eqaution 1 x 13 is equal to 13.

2. 1/2 is the same as saying half, so we know that will be less. 1/4 is one fourth so that will also be less.

3. Again, it will be half of 2,175 so we know that's less.

4. Still with the same theme as the other questions it will be half of 54,811.

5. Once again, 1/2 is 50% as I'm sure you know. Meaning she sold half the copies.

PLEASE let me know if that helped or didn't make sense at all.

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
