Step-by-step explanation: because u can’t divide 7.25 and 7
I think about 870? Because I’m pretty sure your suppose to do subtraction

Step-by-step explanation:
Hope this helps!
Let the number of musicians in the marching band be x, then
250 - 130 + 130 + x - 130 = 375
120 + x = 375
x = 375 - 120 = 255
Therefore, 255 musicians are in the matching band.

infinite geometric series
A1
= 880
r = 1 / 4
The sum of a geometric series in sigma
notation is:
n 1 - r^n
∑ Ai = A ----------- ; where A = A1
i = 1 1-r
When | r | < 1 the infinite sum exists and is equal to</span><span><span>:
∞ A
∑ Ai = ---------- ; where A = A1
i = 1 1 - r</span>
So, in this case</span><span><span>:
∞ 880
∑ Ai = -------------- = 4 * 880 / 3 = 3520 /3 = 1173 + 1/3

Answer: 1173 and 1/3
