Answer:
Erica: 20
Bo:15
Step-by-step explanation:
(2x - 10) + x =35
3x-10=35
3x=35+10
3x=45
x=15
2x-10=30-10
30-10=20
Answer:
b = 363
Step-by-step explanation:
Sum of a geometric Progression is expressed as attached.
a = 3 = the first term
r = 3 = the common ratio
n = 5 = number of term
Sum of GP = a(r^n - 1)/ r-1
= 3(3^5 - 1)/ 3-1
= 3(234 - 1) / 2
= 3(242) / 2
= 726/2
= 363
