2a+3c=56, a+4c=49.50
2a+3c=56.00
-2(a+4c=49.50)
_______________
2z+3c=56
-2a-8c=99
____________
0+-5c=-43
-5c=-43
c= -43/-5
child ticket=8.60
now take c and plug the answer into the first equation: 2a+3c=56, 2z+3(8.60)=56, 2z+25.80=56, 2a=56-25.80, 2a= 30.20, a=30.20/2, adult tickets =15.10
Answer:
<h2>
Marianna is incorrect because x2</h2><h2>
2x13 can be factored into two binomials</h2>
Step-by-step explanation:
ax^2+bx+c = 0
x=−1+√14 or x=−1−√14
discriminant=56
completing square x=−1+√14 or x=−1−√14
Now, we can solve each term for
x=-2 she is incorrect
x(x+2)=0
Now, we can solve each term for
0:
x=0
- no other work needed,
and
x+2=0
x+2-2=0-2
x+0=-2
<u>x=-2</u>
