10✔️9x = 60
✔️9x = 60/10
✔️9x = 6
9x = 6^2
9x = 36
X = 36/9
X = 4.
I believe this would be the solution.
Answer:
x =1+i√11/2,1−i√11/2
Step-by-step explanation:
/2 means that everything before it is divided by 2. Basically, each side is divided by 2, it just wont let me do that function on here ;)
Hope this helps!
#4(a)
row-seat: 3- 13, 4-15, 5-17, 6-19, 7-21
(b)
the equation works for row 1 but not for any of the rows after this
Ex: Row 2, S=7(2)+2, this would equal 14 but there isn't 14 seats in row #2
(c)
S=2(1)+7, there is 9 seats in row 1
2(2)+7=11, there is 11 seats in row 2
2(3)+7= 13, there is 13 seats in row 3
(d)
2(15)+7=37
2*15=30, 30+7=37
(e)
91=2(r)+7
91-7=2(r)+7-7
84=2(r)
84/2=2(r)/2
42=r, the row with 91 seats is row 42
