Let unknown number be x
3x + 5 = 65
3x = 60
x = 20
Therefore, unknown number is 20.
X+3y=3
First add subtract the x
3y=-x+3
Then divide 3
Y=-1/3x+1
Answer:
5/6 is greater
Step-by-step explanation:
First obtain a common denominator for the fractions. Multiply the denominator of one fraction to the denominator of another and that is the denominator for the new fractions (54). Then multiply the denominator of one fraction to the numerator of the other one to obtain the new numerator. (e.g. 5*9=45 so 5/6 ->45/54) do this to the other fraction and you will see that 7/9 -> 42/54 and 45/54 is greater than 42/54 so 5/6 is greater .
If I am rolling a single dice what is the probability of rolling a number that is divisible by 2 and 3? The only number divisible by 2 and 3 is 6. So, would the answer be 1 out 6 or 1/6
The common denominator would be 18. So, 5/6 becomes 15/18 and 7/9 becomes 14/18
