check the picture below.
recall that, if the endpoint has a hole ○ , that number is not included, so the "x is not equal" to that, and if there's a solid ball, ●, that means is included, "x equals" that.
Saturday 4 1/2
Sunday 7 1/3
First you would have to find common denominator
4 1/2 + 7 1/3
4 3/6 + 7 2/6 = 11 5/6
So, Tim ran a total of 11 5/6 miles on both days.
Hope that helps you. :-)
A.
3x = 2y – 4
B.
3x – 2y = –4
C.
3x + 4 = 2y
D.
3x – 2y + 4 = 0
P( skiſ does not wake board)
Answer:
10% of the students ski and do not wake board
Step-by-step explanation:
The total number of students is 120. 28 students ski while 52 students wake board. 16 of the students ski and wake board.
Let S represent students who ski and W represent those who wake board also W' represent those who do not wake board.
Therefore:
S = 28
W = 52
n = total number of student = 120
S ∩ W = those who ski and wake board = 16
Those who ski and do not wake board = S ∩ W' = S - (S ∩ W) = 28 - 16 = 12
Probability of those who ski and do not wake board = (S ∩ W') / n = 12 / 120 = 0.1 = 10%
10% of the students ski and do not wake board
Answer:
27
Step-by-step explanation:
first do 18/2 and then do 9x3 and you get 27
With the given ratio of 9 glasses per container, Myra can fill 27 glasses of iced tea by using 3 containers.
The subject of this question is ratio and proportion which falls under Mathematics. Based on the information given in the question, Myra can fill 18 glasses of iced tea with 2 containers. That's a ratio of 18 glasses to 2 containers, or simply put, 9 glasses per container (18 glasses ÷ 2 containers).
So when Myra tries to fill glasses with 3 containers of iced tea, we would just multiply the 'glasses per container' by the number of containers she is using. This calculated as (3 containers × 9 glasses/container) which equals 27 glasses. Hence, Myra can fill 27 glasses with 3 containers of tea.

substitute the coordinates of the ordered pair into either equation to see if it produces a true statement
B.
substitute the coordinates of the ordered pair in both equations to see if it produces a true statement for each
C.
substitute the coordinates of the ordered pair in the first equation to see if it produces a true statement
D.
substitute the coordinates of the ordered pair in the second equation to see if it produces a true statement
Answer:
B
Step-by-step explanation:
When an ordered pair is a solution to a system of equations in two variables, it must mean that when you plug in the ordered pair into both equations, it must come out true (this is literally the definition of a solution to a system of equation). Technically, A is also facts, but B is a "more inclusive" facts so that's your answer. Hope this helps! :)
