Answer:
144 children and 170 adults
Step-by-step explanation:
make 2 equations
make :
the children as the regarded as the variable : x
the adults are the regarded as the variable : y
<em>5x + 6 y = 1740</em>
<em>x + y = 314</em>
<h3><u>solve this by the method of elimination </u></h3>
5x + 6y = 1740
5(x + y = 314)
= 5x + 5y = 1570
5x + 6y = 1740
5x + 5y = 1570
the 5x is cancelled out
6y - 5y = 1740 - 1570
y = 170
now replace the value of y in the eqaution
5x + 6 (170) = 1740
5x =720
x = 144
hence they were 144 children and 170 adults

I believe it is associative because you can plug in 7 for be and still get the same answer as if you put in b for 7.
X1 - 3 = x2
subtract 3 from the first value to get the second one
Answer:
Step-by-step explanation:
After x=2, we see that the change in y over the change in x is positive since both variables increase with each other, so is where the function is increasing.
