Answer:
(a)
A single avocado costs $1
A single tomato costs $0.5
(b)
An avocado costs twice as much as a tomato
<em></em>
Step-by-step explanation:
Represent the tomatoes with T and the avocados with A.
So, we have:
--- (1)
--- (2)
Solving (a): The price of each
Multiply (1) by 1.5
--- (3)
Subtract (3) from (2)
Divide both sides by 2
Substitute 1 for A in (1)
Make 4T the subject
Divide both sides by 4
Solving (b): Analysis
In (a), we have:
<em>We can say that an avocado costs twice as much as a tomato</em>

Answer:
The linear equation is y = 10 x
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- Rise rate = 10 ft per second
For each unit of time, we get ten units of height.
So, the linear equation is
y = 10 x
Where "y" is the height of the balloon after "x" seconds.
If we replace the variable x for a value we obtain the height.
For example, after 1 second:
y = 10 ft / sec x 1 sec
y = 10 feet
