Answer:
x = 6
Step-by-step explanation:
3 (2x - 5) = 21
=> 6x - 15 = 21
=> 6x = 21 + 15
=> 6x = 36
=> x = 36 / 6
=> x = 6
OR
3 (2x - 5) = 21
=> 2x - 5 = 21 / 3
=> 2x - 5 = 7
=> 2x = 7 + 5
=> 2x = 12
=> x = 12 / 2
=> x = 6

Explain how you can tell whether a group of ratios represents a proportional relationship.
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.

Match the correct graph to the story below.
A golfer hits a golf ball.
x = the time that has elapsed in seconds.
y = the height of the ball off the ground.
C. is the correct graph that describes hitting a ball with a golf bat.
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
Given, A golfer hits a golf ball, where x is the time in seconds and y is the height of the ball.
Now when a golfer will hit the ball as time progresses it will gain a height after some time just before falling down the ball will attain its maximum height and then it falls gradually influenced by gravity.
