Answer:
huh what do you mean
Step-by-step explanation:
im really sorry
By definition of absolute value, if 
, then 
, so
On the other hand, if 
, then 
, and
X=number of adults, y= number of students
x+y=12
18x+12y=162
You can simplify the second equation by dividing by six: 3x+2y=27
Rearrange the first equation: y= 12-x. Plug y into the simplified second equation:
3x+2(12-x)=27
3x-2x+24=27
x=3.
Plug the now known x value into y=12-x. So y= 9.
Therefore, there are 3 adults and 9 students.
4 / 5
use the 7 to reduce each numer of the fraction
Answer:
A. x^2 + 3x + 2
D. 3x^4 + 4x^3 - 3x^2 - 1
E. 3t^3 + 3t^2 + 2t
Step-by-step explanation:
Standard form is where the equation is set up so that the exponents decrease from left to right, and where you put a number with no variable or exponent last.
