Answer 1
Answer: Answer is D. Y=11 12*y-(-132=0
12y+132=12•(y+11)
Answer 2
Answer: 12y = 132 

(12y)/(12) = (132)/(12)  Divide \ both \ sides \ by \ 12

Which are natural numbers, integers, rational numbers, irrational numbers and real numbers?0, 1, 1/12, 1/16, 1/20

Answers

-Natural numbers are 0+ (no negative or decimals)
-Integers are any number that is not 0 or a fractional number (# with decimals/fractions)
-irrational numbers are numbers with decimals that go on forever and that do not repeat themselves
-rational number is any number that is predictable. So negative numbers, 0 and any number above 0 and decimals that are predictable (ex: 5.2)  or any repeating decimal not decimals that goes on forever bu does not repeat them self for example π-real numbers are any digit that is rational. This includes negative numbers and fraction.

so to answer your question

0: Natural number, real number, rational
1: Natural number, Integer, real number, rational
1/12: real number, rational
1/16: real number, rational
1/120: Real number, rational

natural numbers are counting numbers (1,2,3,4,5...), not including 0

integers are natural numbers plus their negatives and zero (-3,-2,-1,0,1,2,3..)

rational numbers can be written in form a/b where b is not equal zero, terminating and repeating decimals can be written in this form

irrational numbers cannot be written in form a/b, they are non-terminating decimals

real numbers are rational+irrational numbers, not including imaginary numbers

basially
natural numbers are in integers which are in rational numbers which are not integers and those make up real numbers

so


0 is a whole number but that wasn't listed so it is an integer, rational number and a real number

1 is a natural number, an integer, a ratioal number, and a real number

1/12 is in form a/b, so it is a rational number and a real number

1/16 is also in form a/b, so it is a rational number and a real number

1/20 is also in form a/b, so it is a rational number and a real number

Mrs. Torres’s class has 28 students. The class includes 12 boys. What is theratio of girls to boys?

Answers

Answer:

16:12 or 4:3

Step-by-step explanation:

Girls + boys = 28

Girls + 12 = 28

Girls = 16

Girls to boys:

16:12

16/12

4:3

Answer:

4:3

Step-by-step explanation:

Because there are 12 boys out of the 28 students in the class, there would have to be 16 girls in the class. This information would make the ratio 16:12. Although that is not the lowest you can go, so you would divide both numbers by the same value, to get both as low as possible, in this case, you would divide both by 4. Now your ratio is 4:3, which can also be said as, for every 4 girls in the class, there are 3 boys.
