Here is the set up:
Let m = mass of the block
m = (30•40•50)/(2.8)
Use your calculator to calculate the left side for m.
Answer:
21
Step-by-step explanation:
1/3= 0.33
7/0.33
Step-by-step explanation:
25m + 10b = 400
not enough info to solve for m or b. but that's the equation you would use.
Step-by-step explanation:

- In the line 2, only variables were operated with a reduction of similar terms in each side of the equation, giving as result -4x at one side, and 2x at the other side.
- In the line 3, terms with variables were joined together in one side of the equation, and then, they were operate it, given as result -6X.
