Solve by factoring:<br> 5t=t ^2
elena-14-01-66 [18.8K]

Answer:

t=0 and t=5

Step-by-step explanation:

5t = t^2

Subtract 5t from each side

5t-5t = t^2 -5t

0= t^2 -5t

Factor out a t

0= t(t-5)

Using the zero product property

t=0  and t-5 =0

t=0  and  t-5+5=0+5

t=0 and t=5

Tickets to a show cost different for seniors, children, and adults. Adult tickets are twice as much as senior tickets. Two senio
aleksklad [387]
A = 2s
c + 2s = 17 .....c + a = 17 (I subbed in "a" for 2s)
2c + a = 24

c + a = 17 .....(-1)
2c + a = 24
---------------
-c -a = -17...result of multiplying by -1
2c + a = 24
---------------add
c = 7

2c + a = 24
2(7) + a = 24
14 + a = 24
a = 24 - 14
a = 10

a = 2s
10 = 2s
10/2 = s
5 = s

so, senior tickets (s) cost $ 5,  adult tickets (a) cost $ 10, and child tickets (c) cost $ 7

1 adult ticket + 1 senior ticket would cost $ 15
