Let's first put 8/9 and 5/12 in simplest form.
We need to have the denominators at the same value by find the greatest common multiple.
The GCM of 9 and 12 is 36. By making both denominators 36, we also have to change the numerator.
36/9 is 4 so the numerator of 8/9 has to be multiplied by 4, making that 32/36.
36/12 is 3 so the numerator of 5/12 has to be multiplied by 3, making that 15/36.
Now, that we have the same denominators, we can subtract.
32/36-15/36 can be done simply by just subtracting the numerators together. Remember, the denominators stay the same.
32/35-15/36 = 17/36
Since there is no least common multiple of 17 and 36, then 17/36 is the final answer.
Answer:
20 dollars per month
Step-by-step explanation:
85 = 25 + x3
60 = x3
20 = x
The answer for the problem shown in the figure attached is the option b, which is:
b: (7,11,1); 3√19
The explanation for the exercise is:
1- To solve this problem you must apply the proccedure shown below:
2- You have:
R(3,7,-1) and S(10,-4,0)
3- Then S-R is:
(7,-11,1)
4. And the magnitude is:
|RS|=√(7^2+(-11)^2+1^2
|RS|=3√19
0.462
You just move the decimal point 2 places to the right
hope this helps!
Answer:
-32.4
Step-by-step explanation:
-1.2/(-0.4) = 3
-3.6/(-1.2) = 3
-10.8/(-3.6) = 3
Each new terms is the previous term multiplied by 3.
-10.8 * 3 = -32.4
