Answer:
Step-by-step explanation:
Sum of angles of a triangle = 180
x + (180 - 105) + (180 -140) = 180
x + 75 + 40 = 180
x = 180 -75 - 40
x = 65

Answer:
Step-by-step explanation:
Let's look at simpler cases. If there was just one visit that would be 124. if there were two, each time he'd have to pay 124 so it's 124+124 = 248. So this is multiplication, because next would be three, which is 124+124+124 or 124 time 3.
In total then it's 124*14. You may usually use an x for multiplication, and if you do just keep in mind * can also be used. or, if something is inside of parenthesis like this 124(14) or (124)14. If you need help doing the multiplication let me know.
