Step-by-step explanation:
x+y=29...because x and y means how many tickets they have
and if normal 1 ticket is 70...then x number of tickets are $70x.
and
1 VIP ticket is 80...then y number of tickets are $80y..got that?...sum of all earned by selling tickets equal to $2130
so...
70x+80y=2130
so...equations are
x+y=29
70x+80y=2130
solve these equations.i did the hard part...you will get the answer...if u dont know hot to solve this comment me...
Answer:
A
Step-by-step explanation:
Find the slope of the perpendicular line.
The slopes are related by the formula
m1 * m2 = - 1
Since m1 is 1/2, m2 must be -2
So far what you have is y = -2x + b
Find the y intercept (b).
The new line goes through (4,1)
x = 4
y = 1
1 = -2(4) + b
1 = - 8 + b
b = 1 + 8
b = 9
The answer is
y = - 2x + 9

C) 273 ft²
Step-by-step explanation:
7x11x3=231
2x1/2x7x6=42
231+42=273
Answer:
2.20
Step-by-step explanation:
The GPA is the weighted average of the grade points. The weights are the number of course hours.
((16 hours)(3.0) +(7 hours)(1.0) +(21 hours)(2.0))/((16 +7 +21) hours)
= 97/44 ≈2.20 . . . . GPA
