So here first you have to have same denominators to subtract and add.
to make same denominator you have to multiply something to them which meets up to their lowest common multiple (LCM). so here the easiest thing is multiply each denominator to the other but remember you have to multiply them to the numerator too.
3×9/5×9-2×5/9×5
so it becomes
27/45-10/45
17/45
as you cant bring to its simplest form since the answer in a prime no. leave it like that.
Answer:
0.25x + y = 12
Step-by-step explanation:
Given
Kiran is spending $12 on games
it means that he can spend total of $12 on rides and games
number of games is represented by x
cost of 1 game = $0.25
cost of x games = $0.25*x = $0.25x
number of rides is represented by y
cost of 1 rides = $1
cost of x rides = $1*y = $y
Total cost for x games and y rides =cost of x games + cost of y rides
Total cost for x games and y rides = $0.25x + $y
given that Kiran is spending $12 on games
Total cost for x games and y rides will be $12
thus,
$12 = $0.25x + $y
removing dollar sign for equation formation
0.25x + y = 12
given above is the equation to represent the relationship between the dollar
amount Kiran is spending and the number of games, x, and the number of
rides, y.

Answer:
The correct option is D
D) She may not be correct because means cannot be determined from the box plots
Step-by-step explanation:
The question is incomplete because the box plots are not attached in the question. I've attached the box plots of this question at the bottom.
The box plot, also know as box and whisker plot, displays only five type of values, which are:
- Minimum value
- First Quartile
- Median
- Third Quartile
- Maximum value
Mean cannot be determined by just lookin at the box plots. To find the mean, we need to know the values of data and total number of values.
As mean cannot be determined from the box plot, correct option is D
