If x is the amount that Tanya paid for each item, then Tony's items would be x-2.25. So:
3x=4(x-2.25)
3x=4x-9
x=9
x-2.25=6.75
Tanya spent $9 on each item; Tony spent $6.75 on each of his items
Answer:
A) it converges
B) 1998.047
C) 2000
d) The sum is getting smaller and smaller
Step-by-step explanation:
Formula: a_n+a_1*r^(r-1)
(1000*((0.5^10)-1))/(0.5-1)=1998.047
(1000*((0.5^30)-1))/(0.5-1)=2000
Hello from MrBillDoesMath!
Answer:
-6.9
Discussion:
1.3n - 0.03 = -9 => multiply both sides by 100
130n - 3 = -900 =>
130n = -900 +3 = -897 => add 3 to both sides
n = -897/130 =>
n = - (69 * 13)/ (10*13) =>
n = - 69/10 = - 6.9
