Answer:
49
Step-by-step explanation:
26- (-23)
26 + 23 This is because when you have a negative times a negative it equals a positive.
Step-by-step explanation:
Bringing like terms on one side
2 + 7 - 5 = 2x - 4x
9 - 5 = - 2x
4 = - 2x
4/ - 2 = x
- 2 = x
B is the correct answer because 1 gallon of gas is 1.05 dollars, so 15 × 1.05 is 15.75...
7 + (4^2 + 5) x 2 = 51
(2 + 3) x 3^2 + 39 / 3 = 54
2 x [(4 + 3) x 5 - 6] = 58
[84 / (3 + 4)] x 3 + 1 = 37
Therefore none of them equal 52!
