40 is the distance. You are rounding up so 40 is the nearest answer
Answer:
4
Step-by-step explanation:
The question says that restaurants often slip takeout menus under Maura's apartment door. So far, Maura has collected 15 menus, including 3 for Chinese food. Considering this data, we were asked to find out how many of the next 20 menus slipped under Maura's door should you expect to be from Chinese restaurants?
---Since Maura has collected 3 Chinese menus from a combuned total of 15 various menus,we can estimate the number of combined/total menus that she has to receive in order to be able to have access to a single Chinese menu.
--- For every 15 menus,3 Chinese menus are included.That means that 15/3 = 5 menus.
For every 5 menus,there is a Chinese menu
--- To estimate the number of chinese menus available to Maura after 20 different menus was slipped under her apartment door.
Since that for every 5 menus,there is a Chinese menu.The number of Chinese menus in 20 combined menus is
15/20 = 3/x
Cross multiply and we have
60 = 15x
X = 60/15
X = 4
The number of Chinese menus in 20 combined menus is 4
Substitute for x in the second equation:-
2(y + 3) + y = 9
2y + 6 + y = 9
3y = 9 - 6 = 3
so y = 3/3 = 1
Now plug this value of y into first eqution:-
x = 1 + 3 = 4
So you answer is x = 4 and y = 1.
Answer:
1 = - 1/5
2= - 1/7
3= 3/6
Step-by-step explanation:
the step by step instructions are on the pic. but simply...
go the the full number then count from there. for example:
#2 - you go down 5 then since it says negative u go over 1 to the left then 2 down.
This has nothing to do with zero. It is not mentioned at all. If y = 0 then D would apply, but no such restriction is present. The answer is not D
There has to be 3 numbers multiplied together to use the associative properties of multiplication as in (2 * 3) * 5 = 2 * (3 * 5) . The order that we multiply does not matter.
The commutative property could be true, and it is you second best answer (believe it or not) but, 1 * y = y * 1 is kind of trivial. So don't pick B until we find out about A
This often shows up 1 * x is the same thing as x. This is called the multiplicative identity.
