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>
410 - x/7 +70 = 120
410+70-120=x/7
360=x/7
X =2520
The graph is the one that correctly represents the linear piece-wise function is the first graph.
<h3>How to solve for the graph</h3>
First we have a linear function as
Mx + b
mc= slope, this is the rate of change, how y changes as x changes by 1.
b = y-intercept, y value as x = 0
y = 5 + x
x ≤ 10
at 10 we have 5 + 10 = 15
at 2 dollars
y = 15 + 2(x - 10)
at 14
y = 15 + 2(14 - 10)
15 + 2*4
= 23
Hence we can conclude that the first graph here is the correct one.

Answer:
x= 41
Step-by-step explanation:
To answer this question, we know that a triangle has a total of 180 degrees. So we can add all of the angles and set them equal to 180 degrees, then solve for x.
x+(x+70)+28=180
2x+70+28=180
2x+98=180
2x=82
x= 41
