Answer:

17) x=4

19)x= all real numbers

Step-by-step explanation:

Just switch the y for its give value

17) 4x-3(0)=16

3*0=0

4x=16

4x/4=16/4

X=4

19)-6x+3(2x)=0

3*2x=6x.

If you have - 6x and +6x then any number works for x.

Your answer to number 17 is x=4 because you replace y with 0 and you get 4x-3(0)=16. Then you multiply 3 by 0 to get 0 and get 4x=16 as ur equation. Then you can divide both sides by 4 to get 4 as your x.

Your answer to number 19 is 0 because 3(2x)-6x=0 is also known as 6x-6x=0 which equals 0.

Answer:

a)  12/91

b) about 67 times;  (66 2/3)

Step-by-step explanation:

a) total of frequencies is 90 and frequency for a 3 is 11

however, the question said if the dice is rolled once more, then that raises the 11 to 12 and the frequency total from 90 to 91

let 'x' = # of sixes rolled out of 500 times

b) 12/90 = x/500

cross-multiply:

90x = 6000

x = 66 2/3

ExtremeBDS [4]

Answer:

well if the max grade he could get was 100 then you need to find 15% of 100 which is 15, after that add 15 to 80 and you get 95.

his grade for exam 2 was 95

Step-by-step explanation:

15% of 100 = 15

80 + 15 = 95
