You can divide both sides by 5, then you would have the answer:
X/5 = y
Hope this helps! :)
Step-by-step explanation:
t8 = a1 + (n - 1)*d
t8 = 17
17 = a1 + 7*d
t12 = 25
25 = a1 + 11d
17 = a1 + 7d Subtract
8 = 4d Divide by 4
8/4 = 4d/4
2 = d
17 = a1 + 7d
17 = a1 + 7*2
17 = a1 + 14 Subtract 14
3 = a1
Sum 20 terms
The 20 term = a1 + 19*2
The 20 term = 3 + 38
= 41
Sum = (a1 + a20) * 20 / 2
Sum = (3 + 41)* 20/2
Sum = 44 * 10
Sum = 440
Answer:

Step-by-step explanation:
Answer:
r =.3 is wrong for 2x = -6. you divide -6/2 which = -3 so r = -3
5 + 7 = 12 silver balloons
12 x 3 = 36 bronze
12 + 36 + 5 = 53
