Explain how you can tell whether a group of ratios represents a proportional relationship.
Answers
Answer:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.
(Hope this helps!! Btw, I am the first to answer.)
A group of ratios represents a proportional relationship. When the connection is proportional if the ratio remains constant. Explanation is given.
What is proportional relationship?A proportional relationship is a relationship between two expressions and where changes in one expression means some constant change in the other expression as well. Generally, it is represented as x/y = k, where x and y are two expressions and k is constant.
Ratio:
The numerical relationship between two values that demonstrates how frequently one value contains or is contained within another.
An ordered pair of integers 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 ratios between the two variables should be considered in order to determine whether a relationship is proportional.
The connection is proportional if the ratio remains constant.
Therefore, the relationship is proportional if the ratio remains constant.

13/20 simplified and 52/80 not simplified
Step-by-step explanation:
So this is pretty simple.
First: Write out the problem on a piece of paper.
Second: Cross out all the 1's and 2's because those represent a made field goal.
Third: Count the number of 3's, 4's, 5's, and 6's.
Fourth: That gets you to 52. This is your numator.
Fifth: Count the total number of 1's, 2's, 3's, 4's, 5's, and 6's. That is 80. That is now your demoinoator.
Sixth: 52/80 is simplified to 13/20.

Veronica spent a minimum of $65 on a doll and accessories for the doll. The doll cost $26 and the accessories cost $13 each. Write an inequality can be used to find the possible values for x, the number of doll accessories Veronica could have bought.
Answers
Answer: [tex]13x+26 \ge 65[/tex]
If you solve for x, you get [tex]x \ge 3[/tex] which means she bought at least 3 accessories.
=========================================================
Explanation:
x = number of accessories, some nonnegative whole number
13x = amount spent on accessories only
For instance, let's say she bought 5 accessories. This means she spent 13x = 13*5 = 60 dollars on those five items.
This is on top of the $26 Veronica paid for the doll itself (without the accessories). In total, she spent 13x+26 dollars for the doll (26) and the accessories (13x) combined.
We're told she spent a minimum of $65, which means that she spent 65 or more dollars.
So the total cost (13x+26) must be equal to 65 or larger than 65.
We write that as [tex]13x+26 \ge 65[/tex] which sets up the inequality.
----------------------------
Let's solve for x
[tex]13x+26 \ge 65\\\\13x \ge 65-26\\\\13x \ge 39\\\\x \ge 39/13\\\\x \ge 3\\\\[/tex]
So x can be equal to 3, or larger than it.
The lowest value x can be is 3.
Meaning that she bought at least 3 accessories (ie she bought 3 or more accessories).
Answer:
Step-by-step explanation:
65= 26+13x
