Let Alex's age is x and June's age is y y - x = 7 .........(1)
(x+5) + (y+5) =31
x + y = 21 .........(2)
by adding 1 and 2
2y = 28
y = 14
x = 7
Given:
Customers can pick their own blueberries at Blueberry Hill. They pay $5 to enter the patch and $4 per pound for the blueberries they pick.
Required:
We have to write an equation to model the given expression.
Explanation:
Let the total cost be y,
And x denotes the amount in pounds of blueberries.
Since, Given to enter the patch customers pay $5 (fixed)
and Given the customers pay $4 per pound for the blueberries they pick so for x pounds of blueberries cost 4x
Thus, total cost y = 4x + 5
Thus, Option (a) is correct.
Answer
Thus, Option (a) is correct.
Answer:
Roster Form of M = {-2, -1 , 0, 1}
Set Builder Form of M = {x : x is an integer and -3 < x ≤ 1 }
Step-by-step explanation:
Roster Form: A set is said to be in roster form if each element of the set is written distinctly in the set with commas in between them.
Set Builder Form: A set is said to be in set builder form if all the set elements are represented by describing their properties.
Now, here M is the set of integers that are greater than -3 and less than or equal to 1.
So, by definition of the set forms,
Roster Form of M = {-2, -1 , 0, 1}
Set Builder Form of M = {x : x is an integer and -3 < x ≤ 1 }
