Answer:
The correct answer is $12
Step-by-step explanation:
To check, subtract 12 from 31
31 - 12 =19
Multiply 19 by 2
19 x 2 =38
Add 12
38 + 12 =50
56/125-177/625= 280/625 - 177/625 = ( 280 - 177 ) / 625 = 103 / 625 = 0.1648
G is the same function
Using the 2nd function
g(2) = 8 - g(2-1)
g(2) = 8 - g(1) (g(1)=50 )
So, g(2)= 8-50
g(2) = -42
Answer:
a) 26
b) 26/3
Step-by-step explanation:
a)
1) First, you have to turn 4 1/3 into an improper fraction, so you get 13/3
2) Then you do 13/3 *6/1 =78/3 (so you multiply both numerators and denominators)
3) Lastly, 78/3 can be simplified as 26
b)
1) First you turn both fractions into improper fractions, so you get 13/5 and 10/3
2) Then you do 13/5*10/3 (so you multiply both numerators and denominators)
3) You get 130/15, which can be simplified as 26/3
