Answer:
$550
Step-by-step explanation:
In this question, we have to find how much a party would cost for 80 people.
We know that our equation is C = 6.50x + 30
"x" is the amount of people.
To found our answer, we would plug in 80 to "x" to find the total cost.
Solve:
C = 6.50(80) + 30
C = 520 + 30
C = 550
This means that the cost of the party for 80 people would be $550.
m_6 + m_8 = 180º because they form a straight line.
So, (2x-5) + (x+5) = 180
3x = 180
x = 60
So, m_115º (2•60 - 5 = 115)
Also, because the two lines are parallel m_6 = m_3 by alternate interior angles.
So, m_3 = 115º
300+12x = 450
or
B. 12x+300 = 450
The solution is b
3× -2y-9
4x +3y =22
The answer is D
