Answer:
- (5 +4 +3)×2 -1 = 23
- 5 +(4×3×2) -1 = 28
- 5×(4 +3 +2 -1) = 40
Step-by-step explanation:
The above expressions give the values you requested. I was able to form all integers 1-40 except 39.

<em>Additional comment</em>
I used a computer program to evaluate different sequences of operations. Attached is one result for each integer 1-40 except 39. The notation here is postfix, but is not difficult to translate to infix with parentheses. Starting with the left-most operation (op), the pattern (a, b, op) → (a op b) is used. For example, the listing for 38 is 543+*21++, so this becomes 5*(4+3)+(2+1) = 38.
This turns into
14+4i+21i+6i^2
14+25i+6(-1)
14+25i-6
<em>8+25i </em>is the answer
The answer is 66.75
I would suggest multiplying 2 in (2x+1) by 2 5/8 first, then multipling 4 by 2 5/8. This will garner you 10 and 5.25. Distribute the 9 into the (). You'll then get 10.5+47.25+9
Add and you will get 66.75
Answer:
v =7
Step-by-step explanation:
Simplifying
v + -10 = -3
Reorder the terms:
-10 + v = -3
Solving
-10 + v = -3
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '10' to each side of the equation.
-10 + 10 + v = -3 + 10
Combine like terms: -10 + 10 = 0
0 + v = -3 + 10
v = -3 + 10
Combine like terms: -3 + 10 = 7
v = 7
Simplifying
v = 7
