You need to figure out how many ways you can roll a sum of 9.

3 and 6, 4 and 5, 5 and 4, and 6 and 3. That's 4/36, or a 1/9 chance.

Alex has a 1/6 chance. Therefore, Alex is more likely to win.

Answer:

Alex will win.

Step-by-step explanation:

Sample Response: To roll a 9, you need a combination of 3 and 6, or 4 and 5, in any order. To roll a 6, Alex needs a combination of 1 and 5, 2 and 4, or 3 and 3, in any order. There are 4 possible ways to roll a 9 and 5 possible ways to roll a 6, so Alex is more likely to win.

Answer:

x=14/5

Step-by-step explanation:

Group like terms

2x+8x+7=35

Add similar elements: 2x+8x=10x

10x+7=35

Subtract 7 from both sides:

10x+7−7=35−7

Simplify

10x=28

Divide both sides by 10

10x/10 =28/10

Simplify:

x=14/5

AveGali [126]

Answer:

52 miles per hour

In the first quadrant, you start at ( 6, 5 ) and move 3 units left .
Verdich [7]

Answer:

(3,5)

∧

this is x number

Step-by-step explanation:

the x number is left and right movement. if you move 3 units left you would subtract 3 from the x number. so 6-3=3 and you don't have to do anything on the y value because you don't move it.

Please help guys.......​<br>equation practice
nignag [31]

Answer:

Step-by-step explanation:

m∠AOC = 180 as it is straight line

m∠AOC = m∠AOB + m∠BOC

m∠AOB + m∠BOC = 180

3x + 124 +   6x + 29 = 180

9x + 153 = 180

9x = 180 - 153

9x = 27

x = 27/9

x = 3

m∠BOC  = 6x +29 = 6*3 + 29 = 18 +29 = 47
