Answer:
A. -2 + 12 -2 ^ 3 + 2 ^ 0 * 3
= 10 - 2 ^ 3 + 2 ^ 0 * 3
= 10 - 8 + 1
= 3
B. 9 ^ (1/2)(25) - 8 + 2 + 3 ^ 2
= 9 ^ (1/2)(25) - 6 + 9
= 3 ^ 25 + 3
= 3 ^ 25 + 3
= 847288609446
C. 1/2 * 3/5 * (2 ^ 3 - 6) + 1/5
= 1/2 * 3/5 * 2 + 1/5
= 3/5 + 1/5
= 4/5
Answer:
Step-by-step explanation:
A.
- - 2 + 12 - 2 ^ 3 + 2 ^ 0 * 3 = Exponent
- -2 + 12 - 8 + 1*3 = Multiplication
- -2 + 12 - 8 + 3 = Addition and subtraction
- 5
B.
- (9) ^ (1/2) (25) - 8 + 2 + 3 ^ 2 = Exponent
- (3)(25) - 8 + 2 + 9 = Multiplication
- 75 - 8 + 2 + 9 = Addition and subtraction
- 78
C.
- 1/2 * 3/5 * (2 ^ 3 - 6) + 1/5 = Exponent within parenthesis
- 1/2 * 3/5 * (8 - 6) + 1/5 = Parenthesis
- 1/2 * 3/5 * 2 + 1/5 = Multiplication
- 3/5 + 1/5 = Addition
- 4/5

Answer:
2.5
Step-by-step explanation:\
We can solve it like this
4 + x = 6.5
6.5 - 4 = x
6.5 - 4 = 2.5
SO
4 + 2.5 = 6.5
Answer:
x=0
y=-3
6x-5y=15
x=y+3
Replace x with y+3
6(y+3)-5y=15
Distribute
6y+18-5y=15
y= -3
x=0
