Mrs. Shaw writes this equation on the board. She asks the students to find the solution.
-40 -2(3m + 1/2)= 7m -2

Keith’s work is shown below. What mistake did Keith make?

-40 - 6m + 1 = 7m - 2
-39 - 6m = 7m -2
-39 = 13m - 2
-37 = 13m
-2 11/13 = m

What is the solution of the equation?

5x+2x=49

7x=49

x=7. 35 apples

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
