1.) B
because it says the person buys a ski for 350. He puts down $110 which means to subtract. Now he got a discount which also means to subtract. Then it told that he gave 1/2 them money to his mother. So that too means to subtract.
2.) 2+5n
because it says 2 plus 5 times a number. So 2+5×n
2x + y = 0
2x + 3 = 0
- 3 - 3
2x = -3
2 2
x = -1¹/₂
(x, y) = (-1¹/₂, 3)
The answer is 136 because 7 x 18 is 126 then + 10 is 136
