Answers
The ratio of the 15 blue bracelets and 12 green bracelets is 5: 4. The correct option is D.
What are ratios and proportions?
An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that Kelly has 15 blue bracelets and 12 green bracelets. The ratio of the 15 blue bracelets and 12 green bracelets is calculated as:-
Ratio = blue bracelets / green bracelets
Ratio = 15 / 12
Ratio = 5 / 4
Hence, 12 green bracelets and 15 blue bracelets are distributed in a 5:4 ratio. The right answer is D.

There are four properties of multiplication.
1) commutative property
2) associative property
3) multiplicative identity property
4) distributive property
The above problem shows a commutative property where when two numbers are multiplied together, the product is the same regardless of the order of the multiplicands.
Choice C. c = 4h Choice A. c = h4
Both 4 and h are multiplicands and whichever order they are, they always produce the same product.
For example. h is equal to 10
Choice C. c = 4 * 10 = 40 ; Choice A. c = 10 * 4 = 40.
Same product, different order of multiplicands.
Answer:
c = 4h
Step-by-step explanation:
c = 4h describes a situation where the number of chickens (c) is four times as large as the number of horses.

What are functions ?
A mathematical expression which has two variables , one is dependent variable and the other is an independent variable.
Functions have wide usage and comes with a defined domain and range.
It is given in the question that there are two functions
Function(x) = -0.5x+2
g(x) = 2x-3
It has different values at different points.
The value at which both the functions have same value has to be determined.
To determine that lets equate both the functions
-0.5x +2 = 2x-3
2.5x = 5
x = 2
Therefore the input value that produces the same output value in both charts is 2, Option D is the correct answer.

Answer:
Hence, the input value that produces the same output for the functions represented by the tables is:
x=2
Step-by-step explanation:
We are given a function f(x) and g(x) as:
and
Clearly the function g(x) and f(x) are linear function.
We have to find such input value that gives the same output value for the function.
i.e. we have to find x such that:
g(x)=f(x)
i.e. -0.5x+2=2x-3
⇒ 2x+0.5x=2+3
⇒ 2.5x=5
⇒ x=5/2.5
⇒ x=2
Hence, the input value that produces the same output for the functions represented by the tables is:
x=2
