Hey!

------------------------------------------------

~Cross Multiply

z/42 * 25/70 → 70z = 1050

~Divide 70 to both sides

70z/70 = 1050/70

~Simplify

z = 15

------------------------------------------------

Hence, the answer is \Large\boxed{\mathsf{z~=~15}}

------------------------------------------------

Hope This Helped! Good Luck!

MrMuchimi

If you forget this, fold along the x line, and you should be able to figure it out. Reflecting across the y-axis, the y-coordinate ALWAYS remains the same, but the x-coordinate is transformed into its opposite. If you forget this, fold along the y line, and you should be able to figure it out.
