Answer:
Step-by-step explanation:
an=4=a1+(n-1)*d=0.25+(n-1)*d
so (n-1)*d=4-0.25=3.75
Sn=a1*n+(n-1)*d
a1*n+3.75=8.5
0.25*n+3.75=8.5
-3.75 -3.75
0.25*n=8.5-3.75=4.75
n=4.75:0.25
n=19
so a19=a1+(19-1)*d=4
0.25+18*d=4
-0.25 -0.25
18*d=3.75
d=3.75/18
d=0.208
so a2=a1+0.208=0.25+0.208=0.458
a2=0.458
S = the number of student tickets sold a = the number of adult tickets sold The drama class sold 25 more student tickets than adult tickets to the fall play s = a + 25 The class collected $660 from ticket sales: 6s + 3a = 660 divide both sides by 3 2s + a = 220 by solving the system of equations s = a + 25 2s + a = 220 we find s = 81.67 student tickets a = 56.67 adult tickets

The values of a and b are 4 & 6
Question :
5m^2 - 29m + 20
Steps:
What can u factor to get 20?
you can make 5 and 4 to make 20 so,..
1. Break it into groups
(5m^2 - 4m) + (-25m + 20)
*Factor out m from (5m^2 - 4m) : m(5m - 4)
*Factor out -5 from (-25m + 20) : -5(5m - 4)
2. Then, you can factor out the common term : (5m - 4) because they both have it. And then u would move the m by the -5 so,...
= (5m - 4)(m - 5) <======= <em>Answer</em>
Hope this helped!!!
