It means that x value is between 2 to 7 ( more than 2, but less than 7)
In notation, 2 < x < 7 or (2,7).
answer: 60
age difference is 30 years
10x4=40
40-10=30
when she is 30 he will be 60 because 30(her age) + 30 (age difference) = 60
Answer:
S= 1.<u>3</u>r
Step-by-step explanation:
The 3 is underlined because it was suppose to go on top of the 3 but it didn't give me the option but that means infinity of 3
If you need more information you cant tell me hope this helped!
Answer:
Step-by-step explanation:
we have to divide the given distance by 3.
Then we will be able to find the distance between markers.
Given distance is
Since, there are three markers,
So, we have to divide this distance by 3
So, the distance between markers is-
So, the distance between marker is
Now, we have to convert this into mixed number.
Then, the distance is-
Answer:
infinitely many
Step-by-step explanation:
Add 12-y to both sides of the second equation to put it into standard form like the first equation:
y +(12 -y) = (x -12) +(12 -y)
12 = x - y . . . simplify
x - y = 12 . . . . second equation in standard form
We see this is identical to the first equation. That means every solution of the first equation is also a solution of the second equation. There are infinitely many solutions.
