2,2,2 will be your answer to my calculations
<span>x = number of entries
55x + 10000 - 15x ≥ 55000
First, subtract 10000 from each side
55x - 15x ≥ 45000
Now, we can combine 55x and 15x because they've both got the same variable attached
40x ≥ 45000
Now divide each side by 40 to isolate x (which is the number of entries)
x ≥ 1125
The race needs at least 1125 entries to raise at least $55,000.</span>
X=4
5^3=125 5^2=25
5^3x= 5^2(x+2)
3x=2x+4
x=4
The factors are 1 and 47, since 47 is a prime number.
