Let's build the equation counting how many x's and 1's are there on each side.
On the left hand side we have 5x's and 8 1's, for a total of
On the left hand side we have 3x's and 10 1's, for a total of
So, the equation we want to solve is
Subtract 3x from both sides:
Subtract 8 from both sides:
Divide both sides by 2:
Answer:
Step-by-step explanation:
The weight of an object is the magnitude of the force of gravity acting on the object. It is equal to the product between mass of the object (m) and acceleration of gravity (g):
In this problem, we have 100 sharks; the weight of each shark is
When we have n objects, the total weight of the n object is n times the weight of each object:
Therefore, since in this case
n = 100
The total weight of the 100 sharks is:
