Answer:
an expression is a combination of variables, operations, and symbols *it does not has an equal sign* (that would be an equation)
Step-by-step explanation:
Neither, it is not going straight up or straight right.
Answer: Distance = 4√5
Concept:
Here, we need to know the concept of the distance formula.
The distance formula is the formula, which is used to find the distance between any two points.
If you are still confused, please refer to the attachment below for a clear version of the formula.

Time spent on aerobics is 150 minutes per week and time spent on weight training is 100 minutes per week
Solution:
Given that,
Kay spends 250 min/wk exercising
Therefore,
Exercising = 250 minutes per week
Ratio of time spent on aerobics to time spent on weight training is 3 to 2
Aerobics : weight training = 3 : 2
Let the time spent on aerobics be 3x
Let the time spent on weight training be 2x
Thus,
3x + 2x = 250
5x = 250
x = 50
Thus,
Time spent on aerobics = 3x = 3(50) = 150
Time spent on weight training = 2x = 2(50) = 100
Thus, Time spent on aerobics is 150 minutes per week and time spent on weight training is 100 minutes per week
There are a few, such as 8/10, 16/20, 400/500, the list is almost endless. As long as you can multiply both the numerator and denominator using the same number, you will have an endless amount of fractions.
Here are more;
32/40
20/25
24/30
28/35
36/45
40/50
44/55
etc.
Hope this helps!
