Answer:
63
Step-by-step explanation:
We can easily solve this problem using algebra as follows.
Let Meteorite B be expressed as x.
We know that the combined weight is 84 tons and that meteorite A is 3 times the weight of meteorite B. That means Meteorite B is x/3.
Based on that, let's form an equation:

Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
We ahve the slope m = 1/2 and the point (-2, 1). Substitute:
- point-slope form
Covert to the slope-intercept form (y = mx + b):
<em>use the distributive property</em>
<em>add 1 to both sides</em>
- slope-intercept form
Convert to the standard form (Ax + By = C):
<em>multiply both sides by 2</em>
<em>subtract x from both sides</em>
<em>change the signs</em>
- standard form
Convert to the general form (Ax+By+C=0):
<em>add 4 to both sides</em>
- general form
