2a+1 + 3a+2 +5a-9 you would start by combining like terms
2a+3a+5a= 10a
1+2-9= -6
10a-6=94
then subtract 94-6=88
then divide 88 by 10= 8.8
a=8.8
Answer:
Explanation:
Number the sides of the decagon: 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10, from top (currently red) clockwise.
- The side number one can be colored of five different colors (red, orange, blue, green, or yellow): 5
- The side number two can be colored with four different colors: 4
- The side number three can be colored with three different colors: 3
- The side number four can be colored with two different colors: 2
- The side number five can be colored with the only color left: 1
- Each of the sides six through ten can be colored with one color, the same as its opposite side: 1
Thus, by the multiplication or fundamental principle of counting, the number of different ways to color the decagon will be:
- 5 × 4 × 3 × 2 ×1 × 1 × 1 × 1 × 1 × 1 = 120.
Notice that numbering the sides starting from other than the top side is a rotation of the decagon, which would lead to identical coloring decagons, not adding a new way to the number of ways to color the sides of the figure.

Answer:
1830
Step-by-step explanation:
Sum of smallest 30 positive even numbers is given by
2 + 4 + 6 + 8 + ......... up to 30 terms
= 2 ( 1 + 2 + 3 + 4 + ....... + 30)
= 
Again the sum of largest 30 odd negative numbers is given by
- 1 - 3 - 5 - 7 - ...... up to 30 terms.
= - (1 + 3 + 5 + 7 + ...... up to 30 terms)
{This is an A.P. series having first term 1, common difference 2 and the number of terms 30}
= ![-\frac{30}{2} [2 \times 1 + (30-1) \times 2]](https://tex.z-dn.net/?f=-%5Cfrac%7B30%7D%7B2%7D%20%5B2%20%5Ctimes%201%20%2B%20%2830-1%29%20%5Ctimes%202%5D)
= - 900
Now, Winnie has the sum 930 and Grogg has the sum - 900.
So, Winnie's sum is (930 + 900) = 1830 more than Grogg's sum. (Answer)
