6 0

Step-by-step explanation:

2x+3y=23 2x+3.7=23 2×1 + 3×7 = 23

3y= 23 2×+21= 23 2 + 21 = 23

23÷3 = 7 2x= 23-21

y=7 2x= 2

x= 1

5x+3y=17 5×4+3y=17

5x=17+3 20+3y=17

5×=20 20=17+3y

14÷5 = 4 20=20+y

x=4 y=20-20

y=0

Find the odds in favor of rolling two even numbers when rolling a pair of dice.
VARVARA [1.3K]

Answer:

1/4 or 25%

Step-by-step explanation:

Each dice has six sides, meaning the numbers that are even are: 2,4, and 6, three even numbers per dice. Meaning the chance of rolling ONE dice is 50%. So if you were to get two even numbers on TWO dice, it would be 25% hope this helps.

Find the solution to the system of equations.
harina [27]

Answer:

x=2

y=3

Step-by-step explanation:

y=−2x+7

y=5x−7

Set the two equations equal since they are both equal to y

−2x+7 =5x−7

Add 2x to each side

-2x+7+2x = 5x-7+2x

7 = 7x-7

Add 7 to each side

7+7 = 7x-7+7

14 =7x

Divide by 7

14/7 = 7x/7

2 =x

Now find 7

y = 5x-7

y = 5(2) -7

y = 10-7

y = 3
