Stretch your thinking Will you make a new ten to solve this problem? 59 + 17 explain
Answers
Answer with explanation:
→59 + 17
59 = 60 -1, 17 = 20 -3
= (60 - 1) + (20 -3)
Opening the smaller brackets
= 60 -1 +20 -3
= 60 +20 -1-3→→Using the associative Property of addition,that is [a + (b +c)]=[(a+b)+c]
= 80 -1 -3
= 80 -4
=76
→→I have made two new tens to solve this problem, one while writing, 59 =60 -1, and another one ,while writing number, 17=20 -3.
≡2nd way
5 9 + 17
= 59 +(16 +1)
=59 + 16 +1 →→Opening the smaller bracket
=59 +1 +16 →→Using the associative Property of addition,that is [a + (b +c)]=[(a+b)+c]
=60 +(10 +6)
=60 +10+6 →→Opening the smaller bracket
=70 +6
=76
Here i have made one ten,only while writing number ,16 =10 + 6.

Answer:
The answer is 18 times the number given in the survey.
Step-by-step explanation:
The survey sample is an example of the 396 students. If there are 22 classmates in the survey, you need to turn 22 into 396 for it to work. 22 times 18 equals 396, therefore 18 times the number of green in the survey.

(unit cost)*y = $85
y would represent the number of units bought or sold, and would have to be equal to or greater than 0. This is the domain.
Final answer:
The domain of a function is the set of all possible input values (x). In terms of a real-world scenario where 'y' is a total cost or value, the domain refers to the quantities of a product or service (x) that would result in a total cost of $85.
Explanation:
The domain of a function in mathematics is the set of all possible input values (often designated by 'x'). But in the context of your question where y is a function and the total value is $85, it sounds like you could be referring to a real-world scenario where 'y' might represent a total cost or value in dollars. A function in this context might reflect how different quantities or 'x' values result in a certain cost or 'y' value.
For instance, if you're selling a product for $17 each and you want to know how many you would sell to reach a total of $85, the domain would be all possible amounts of units you could sell (0, 1, 2, 3, etc.). In this case, 5 units would yield a 'y' value of $85, since 5*$17 equals $85. So, the domain would include the number 5, along with any other positive integers up to the point where 'y' total value (the range) doesn't exceed $85.
