Find the unique value of y =3x-2

Answers

Answer 1

Answer:

y=3x-2

Change them side

3x-2=y

Add 2 to both sides

3x-2+2=y+2

3x=y+2

Divide both sides by 3 so we can find the x value

3x/3= y+2/3

x= 1/3 y + 2/3

The best way to put them into a number line is to make sure that they've all got the same denominator, which in this case, will be 24, as this is the lowest common multiple of 3,4 and 8. You will then need to multiply these fractions accordingly. The first one (1/4) will need to be multiplied by 6 to get a denominator of 24, so this will then give you a result of 6/24. The second one (2/3), will need to be multiplied by 8, which will then give you a result of 16/24. The third one (3/4)will also need to be multiplied by 6, giving you 18/24. The final one (6/8) will need to be multiplied by 3, giving you 18/24. You will then need to put these in order, which will be- 1/4, 2/3, 3/4, and 6/8.The alternative method is to turn these into decimals- 1/4 is equivalent to 25%, which is equal to 0.25. 2/3 is equivalent to 66.66%, which is equivalent to 0.66. 3/4 is equivalent to 75%, which is equal to 0.75. 6/8 is also equivalent to 75%, which is equal to 0.75, you can then easily line them up this way.Hope this has been able to help you

C.10
D.13

Answers

If you would like to know in how many games Gordy didn't play, you can calculate this using the following steps:

Gordy played in:
65% of 20 games = 65% * 20 = 65/100 * 20 = 13 games

He did not play in:
20 games - 13 games = 7 games

The correct result would be B. 7 games.

.35*20=7

B.7 is the answer.
