Answer:25
Step-by-step explanation:
Move the variable to one side by subtracting 0.45x from 0.65x and you get 0.20 the divide 5 by 0.20
Answer:
x = 25
0.65x + 5 = 0.45x+ 10
Subtract .45x from each side
0.65x-.45x + 5 = 0.45x-.45x+ 10
.2x +5 = 10
Subtract 5 from each side
.2x+5-5=10-5
.2x= 5
Divide each side by .2
.2x/.2 = 5/.2
x =25
First term = T(1) is obtained by plugging n = 1 into the formula,
thus First term = 1^2 - 4 = 1 - 4
