Answer:
x = 70
Step-by-step explanation:
First to make the equation easy, divide 42 by 3 to get what 1/7 of Z equals.
42 / 3 = 14
Now to get 5/7 of Z, just multiply 14 by 5.
14 x 5 = 70
Hope this helped.
70
convert the decimal & solve for Z.
(3/7)Z = 42
(0.4286)Z = 42
Z = 98
Now,
(5/7)Z = ?
putting the value of Z
(0.714) (98) = 70
