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 [tex]\Large\boxed{\mathsf{z~=~15}}[/tex]

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

Hope This Helped! Good Luck!
