Step-by-step explanation:
(4 - 5) - (13 - 18 + 2)
According to PEMDAS, we should simplify the parentheses first.
= (-1) - (-3)
When you subtract a negative number, you are actually adding.
= -1 + 3
Now, add.
= 2
Hope this helps!
Answer:

The model we'll use is b. 5/3 = 40/w
The mass of the shorter bar is 24 kg.
To solve for the problem, using the formula above, it will looks like this
5/3 = 40/w -- cross multiply
(5)(w) = (40)(3)
5w = 120 -- isolate the w
5w/5 = 120/5
w= 24
