Answer:
1. C. 28/54
2. A. 5/22
Step-by-step explanation:
1. Simplify each fraction to see which of the four are equal to 4/9.
2. Convert each to a decimal to see which is between 2/11 and 3/11.
Answer:
x = 2, y = -1.
Step-by-step explanation:
2x - 5y = 9
3x + 4y = 2
Multiply first equation by -3 and the second by 2:
-6x + 15y = -27
6x + 8y = 4 Adding the 2 equations:
23y = -23
y = -1.
Now substitute this value for y in the first equation:
2x - 5(-1) = 9
2x = 9 +5(-1)
2x = 9 - 5
2x = 4
x = 2.
2(p+1)=24
divide both sides by two
p+1=12
subtract 1 from both sides
p=11
Answer:
It has a 25% chance of landing on 2
Step-by-step explanation:
If it is split into 4 equal parts each 1/4th is 25%
so landing on 2 would be 25%
