Answer:
Step-by-step explanation:
Considering the complete question attached in figure.
Consider
Hadley = x
Parker = y
Greenville = z
Distance between Greenville and Parker = yz = 29
Given that distance between Hadley and Greenville is 13 miles less than the distance between Parker and Greenville.
xz = yz -13 --- (1)
Distance between hardley and greenville = xz = ?
From (1)
xz = 29 -13
xz = 16 miles
So Alan is right that distance between Hadley and Greenville is 16 miles
Answer:
22.05
Step-by-step explanation:
i used a calculator
The system of equation which represent the scenario is;
x + y = 42
x + y = 420.13x + 0.18y = 6.66
<h3>Simultaneous equation</h3>
let
- number of 13 cent stamps = x
- number of 18 cent stamps = y
- Total cost of the stamps = $6.66
- Total number of stamps = 42
x + y = 42
x + y = 420.13x + 0.18y = 6.66
Therefore, the equation which represent the problem is;
x + y = 42
0.13x + 0.18y = 6.66
