Answer:
2 3/4
Step-by-step explanation:
To change an improper fraction to a mixed number
Take 33 and divide by 12
12 goes into 33 two times
2*12 =24
33-24 = 9
2 9/12
We can simplify the fraction
Divide the top and bottom by 3
9/3 =3
12/3 =4
The mixed number becomes
2 3/4
Answer:
0.078125.
Step-by-step explanation:
This is a geometric sequence with first term a1 = 20 and common ratio r = 10/20 = 5/10 = 0.5.
nth term = a1 r^(n -1) so here:
9th term = 20(0.5)^(9-1)
= 20(0.5)^8
= 0.078125.
Answer: See below
Step-by-step explanation:
Isolate x for x-2y+2z=9
3x=9+2y
....(1)
Substitute (1) into the 2nd equation


7y=-3
y=-3/7
Substitute y=-3/7


Isolate z by substituting it



For x =9+2y/3 substitute z=59/21 and y=-3/7



The answer to 2/3-1/3 is 1/3 since there are 2 1/3 in 2/3.
