Answer:
67
Step-by-step explanation:
Because 180-113 is 67.
You would multiply -2 by 11 and get -22. Next your equation would equal to -22+9y=5. You simply subtract -22 from both sides, which basically means you're adding 22. Next your equation would be 9y=27. All that is left to do is divide both sides by 9, and you get that y is equal to 3.
Answer:
3 and 60
Step-by-step explanation:
A proportion is a mathematical expression in which two ratios are shown to be equal.
Hence
is proportion .
it can be also written as a:b= c:d
The four part a,b,c,d can be divided into two groups
- means : b and c are means
- extremes: a and d are extremes
based on above discussion
in proportion 3/15=12/60
3 is in position of a
and
60 is in position of d
Thus, 3 and 60 are extremes in 3/15=12/60 proportion.
Answer: Choice B) Integers include whole numbers and natural numbers.
======================================================
Explanation:
Let's go through the four answer choices to see which are true or false.
- A) False. A rational number like 2/3 is not a natural number (1,2,3,4,...). This is one counterexample out of infinitely many.
- B) True. The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} basically positive and negative values that don't have fractional or decimal components. Zero is included.
- C) False. Similar reasoning as choice A above.
- D) False. A natural number like 7 can be written as 7/1, which means it is a rational number. Any rational number is of the form a/b with a,b being integers and b is nonzero.
