Answer:
7 donkeys
Step-by-step explanation:
Given
A system consisting of donkeys and tourists
Heads = 50
Legs = 114
Required
Calculate number of donkeys.
Represent donkeys with D and tourists with T.
By means of identification; donkeys and tourists (human) both have 1 head.
This implies that
Number of Heads = D + T
50 = D + T ----- Equation 1
While each donkey have 4 legs, each tourists have 2 legs.
This implies that
Number of legs = 4D + 2T
114 = 4D + 2T ---- Multiply both sides by ½
114 * ½ = (4D + 2T) * ½
57 = 4D * ½ + 2T * ½
57 = 2D + T ----- Equation 2
Subtract equation 1 from 2
57 = 2D + T
- (50 = D + T)
---------------------
57 - 50 = 2D - D + T - T
7 = D
Recall that D represents the number of donkeys.
So, D = 7 implies that
The total number of donkeys are 7
The sum of the given expression { (w - 2.4) + (1 - 0.5w) } is 0.5w - 1.4.
<h3>What is the sum of the given expression?</h3>
Given the expression in the question;
(w - 2.4) + (1 - 0.5w)
Remove the parenthesis
w - 2.4 + 1 - 0.5w
Collect like terms and simplify
w - 2.4 + 1 - 0.5w
w - 0.5w - 2.4 + 1
1w - 0.5w - 2.4 + 1
0.5w - 1.4
Therefore, the sum of the given expression { (w - 2.4) + (1 - 0.5w) } is 0.5w - 1.4.
