$750 / $30 = 25 maths teaching kids
$350 / $25 = 14 maths starter kits
if you wanted to see if it was right, you would just do 14*25 and you would get $350
hope I helped!!
Sum of internal angles of any polygon is: (n-2)x180
So measure of an interior edge is ( ( n - 2 ) x 180 ) / n = 140
So 140n = 180n - 360
40n = 360
n = 9
So it's a nonagon.
Hope this helps :)
Answer:
7×6×5×4×3×2×1+5 can be written as 5*[7*6*5*4*3*2*+1] or 5*(1009). So, other than the number and 1, it has 5 and 1009 as its factors too. So it is a composite number.
Step-by-step explanation:
A composite number is a positive integer that has a factor other than 1 and itself.
1.5/-2.5= -.6

2x + 3/12 = 2x/8
2x - 2x/8 = -3/12
2x - x/4 = -3/12; 2 - 1/4 = 1 3/4 = 7/4
7x/4 = -3/12
7x = -3/12 * 4
7x = -1
x = -1/7
