3^3 + 2^7
Step-by-step explanation:
There really is no other way that I can think of other than guessing and checking. 3^3 is 27, when subtracted from 155 gives you 128. 128 can be rewritten as 2^7, leaving your final answer as 3^3 +2^7.

Answer:
2x + y = -10
Step-by-step explanation:
y + 2 = -2(x + 4)
y + 2 = -2x - 8
Add 2x to both sides:-
2x + y + 2 = -8
subtract 2 from both sides:-
2x + y = -10 (answer)
Answer:
126
Step-by-step explanation:
140*10%
change to decimal:
140*.10

140 - 14 = 126
Answer:
86 or 32, depending on the correctness of the syntax
Step-by-step explanation:
We use PEMDAS:
Parentheses: 4(2)5 2-6/(-3)
Exponents: <em>I'm assuming that all the syntax is correct (so no exponents).</em>
Multiplication and Division: 40*2+6 = 80 + 6
Addition and Subtraction: 86
If you copy+pasted this expression, then the original equation would have been: (4(8 − 6)^5)/(2 − 6 ÷ (−3)). We can use PEMDAS:
Parentheses: (4(2)^5)/(2 - 6 ÷ (−3))
- We solve the parentheses individually using PEMDAS:
- Exponents: (4*32) <-- Numerator | Denominator -->(2 - 6 ÷ (−3))
- Multiplication and Division: 128 <-- Numerator | Denominator --> 2 + 2
- Addition and Subtraction: 128 < -- Numerator | Denominator --> 4
We now have the following fraction: 128/4
That simplifies to 32
