When and doubt choose C, it’s always correct
The <u>latest balance</u> in Pat's <u>checking account</u> is the<u> sum</u> of all possible amounts of money Pat has and gets.
It is known that:
- Pat's checking account balance was $540.30 at the end of May;
- Pat received her paycheck of $900.00 in the first week of June.
Therefore, the latest balance in her cheking account is
$540.30 + $900.00 = $1440.30
Answer: $1440.30

Answer: Choice A) 9^2
---------------------------------------------
Work Shown:
(9^6/9^5)^2 = (9^(6-5))^2
(9^6/9^5)^2 = (9^1)^2
(9^6/9^5)^2 = 9^2
Answer: x = 0
y = 2
z = -1
Step-by-step explanation:
The system of equations are
x+y+z=1 - - - - - - - - - - 1
-2x+4y+6z=2 - - - - - - - - - 2
-x+3y-5z=11 - - - - - - - - - 3
Step 1
We would eliminate x by adding equation 1 to equation 3. It becomes
4y -4z = 12 - - - - - - - - - 4
Step 2
We would multiply equation 1 by 2. It becomes
2x + 2y + 2z = 2 - - - - - - - - - 5
We would add equation 2 and equation 5. It becomes
6y + 8z = 4 - - - - - - - - - 6
Step 3
We would multiply equation 4 by 6 and equation 6 by 4. It becomes
24y - 24z = 72 - - - - - - - - 7
24y + 32z = 16 - - - - - - - - 8
We would subtract equation 8 from equation 7. It becomes
-56z = 56
z = -56/56 = -1
Substituting z = -1 into 7, it becomes
24y - 24×-1 = 72
24y + 24 = 72
24y = 72 - 24 = 48
y = 48/24 = 2
Substituting y = 2 and z = -1 into equation 1, it becomes
x + 2 - 1 = 1
x = 1 - 1 = 0
