First question is b because all the rest don’t make sense to them
Part A , the solutions would be where the line lines cross each other, since these lines only cross each other once, there would be one solution
Part B, the solution is where the lines cross, these lines cross at X = 3 and Y = 4 so the solution is (3,4)
The tenth place is the first number to the right of a decimal. To determine if you're rounding or not, check the hundred's place, 2 numbers to the right of a decimal, for 5 or higher. If it's .45, round to .5, if it's .44, round to .4
