Answer:
n+4=32
Step-by-step explanation:
The initial number n gets additional 4 students making the new total number of students to be 32. Therefore, this situation can be represented as
n+4=32
To get the actual number of students before the additio, we make n the subject of formula hence
n=32-4
n=28
Therefore, the initial number was 28 and the equation is n+4=32
Since no choices were provided, the equation that can be modified is n+4=32
The value 5 is a natural number.
Technically, 5 is all of the above, but classifying it as a natural number means that it is rational and an integer(aka whole number).
Add 6 7 and two you get 15 xy subtract -11 and -4 you get positive 7xy add 15 and 7 and you get 22xy
11 square. units × 7 square. units × 1/2= B. 38.5 square. units.
Answer: 
or (1,1)
Step-by-step explanation:
You can apply the Method of substitution.
Knowing that 
(second equation), you can substitute it into the first equation and solve for the variable y:
Now you need to substitute 
into the second equation to calculate the value of the variable x. Then:
Then, the solution is:
or (1,1)
