Answer:
Step-by-step explanation:
the sequence is exponential and the formula is f(n) 16 -r/16-1
Answer:
10
Step-by-step explanation:
let the number be n then half the number is 
n , so
n + 69 = 74 ( subtract 69 from both sides )
n = 5 ( multiply both sides by 2 to clear the fraction )
n = 10
Thus the number is 10
Minust 5x both sides
7x-5x<5x-5x-8
2x<-8
divide by 2 both sides
x<-4
.690 because 6 rounds up to 10 so it would go up to the next tenth
Answer:
15.65 so round it to 16
Step-by-step explanation:
Add 50 and 63.5 then divide by 7.25
