X= number of student tickets
Y= number of on student tickets
x+y=311
0.50x + 1.50y = 385.50
Solve x in 1st equation
X+y=311
X= -y + 311
Now substitute x into second equation to solve for y
0.50(-y+311)+ 1.50y = 385.50
-0.50y+311.50+1.50y=385.50
Y+311.50=385.50
Y= 385.50-311.50
Y= 74
Now substitute y answer to first equation to find x
X+y=311
X+ 74=311
X= 311-74
X= 237
So 237 students tickets and 74 non students tickets
Answer:1/2
Step-by-step explanation:it’s a 50/50 chance
Answer: The equation is true
Step-by-step explanation:
Since x=3 and y= 5
Substitute the values for x and y
y=2x-1
5=2(3)-1
5=6-1
5=5
⇒The equation is true
Problem 1
<h3>Answer: choice B) They are supplementary angles</h3>
--------------
Explanation:
The two angles combine to form a straight angle (which is 180 degrees). Another term for these angles is "linear pair" since they form a straight line.
=================================================
Problem 2
<h3>Answer: choice B) x = 7</h3>
--------------
Explanation:
The diagonal is never used in this problem. For any rhombus, the four exterior sides are always the same length.
=================================================
Problem 3
<h3>Answer: Choice D) 62 degrees</h3>
----------------
Explanation:
We use the angle addition postulate. This allows us to combine angles BAC and CAD to form angle BAD.
(angle BAC)+(angle CAD) = angle BAD
30 + x = 92
x = 92-30
x = 62
angle CAD = 62
I think the root of "3x + 1 = 7" is 2...
