Start with

$-2z+10+7z=16z+7$

Simplify the left hand side by summing like terms (the one involving z):

$5z+10 = 16z+7$

Subtract 5z from both sides:

$10 = 11z+7$

Subtract 7 from both sides

$3 = 11z$

Divide both sides by 11:

$z = \dfrac{3}{11}$

If you have to apply 30 n of force on a crowbar to lift an object that weighs 330 n, what is the mechanical advantage of the cro

shutvik [7]

<span>The answer is: 2. 11 Crowbar is a Class A lever Therefore the mechanical advantage of the crowbar can be given by either: MA = Output distance/Input distance OR MA = Output force/Input force Since, the question gives only the force, we can use the second formula. MA = Output force/ Input Force = 330 N / 30 N = 11</span>
