Ellen can make 10 different amounts.

Use what we know to make equations in order to solve for each governor's salary.
A=governor of state A
B=governor of state B
A+b=283,910. (Their salaries combined)
A=B+50,440 (A earns 50,440 more than B)
Sub A into the original formula to solve for B
B+50,440+b=283,910
2B=283,910-50,440
2B=233,470
B=116,730
Sub B into the formula that's equal to A
A=B+50,440
A=116,735+50,440
A=167,175
I hope this helps!
A=1/2(a+b)h ↔ A= [(a+b).h]/2
Cross multiplication:→2A = (a+b).h.
Divide both sides by (a+b):
2A/(a+b) =h
Total amount of tennis balls:
5 green tennis balls + 2 yellow tennis balls + 6 red tennis balls + 8 blue tennis balls = 21 tennis balls.
The problem says that Tony removes 4 tennis balls without replacement, so:
Let's call Event A= yellow, green, blue, green
P(A) = (2/21)(5/20)(8/19)(4/18)
P(A) = 2.23x10^-3
P(A) = 0.00223
P(A) = 0.223%
7y^3(3y^2-2)-(3y^2-2)
