Give an example of an open equation
a + b = c + d
How can you use an equation to make a prediction from a pattern?
(i don't know)
pizza costs $1.50 per slice. Use a table and an equation to represent the relationship between the number of slices of pizza bought and the total cost
c = cost of the pizza
s = slices of the pizza
c = 1.50s
is the first one and the second one okay? i have NO idea what the second one is talking about... can you help please? Thanks
just with the second one really. i looked at the ones below and is it okay if i used what Ms. Sue said to shy gurl?
Yes, both the first example equation, "a + b = c + d," and the second equation, "c = 1.50s," are correct.
Let's start with the second question about using an equation to make predictions from a pattern. In this case, you're given a pattern related to the cost of pizza slices. By creating a mathematical equation, you can represent the relationship between the number of pizza slices bought and the total cost.
In the equation c = 1.50s, "c" represents the cost of the pizza and "s" represents the number of slices. The coefficient 1.50 indicates that each slice costs $1.50. When multiplied by the number of slices "s," it gives you the total cost of the pizza.
To use this equation to make predictions, you can substitute different values for "s" to determine the corresponding cost "c." For example, if you want to know the cost of 4 slices of pizza, you substitute s = 4 into the equation:
c = 1.50 * s
c = 1.50 * 4
c = 6
So, according to the equation, 4 slices of pizza would cost $6.
You can create a table to show the relationship between the number of slices and the total cost. Here's an example:
Number of Slices (s) | Total Cost (c)
-------------------------------------
1 | $1.50
2 | $3.00
3 | $4.50
4 | $6.00
... | ...
By plugging in different values for "s" into the equation c = 1.50s, you can determine the corresponding total cost. This allows you to make predictions about how much it would cost for different numbers of pizza slices.
