Answer:
First choice A : 2x +3y is <em>less than or equal </em><em>to</em><em> </em>18. x <em>greater</em><em> </em><em>than</em><em> </em><em>or</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em>0. y <em>greater</em><em> </em><em>than</em><em> </em><em>or</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em>0.
Let the number of seats in section A be x, that of section B y and that of secyion C z. Then
x + y + z = 52000 . . . (1)
x = y + z . . . (2)
42x + 36y + 30z = 1960200 . . . (3)
Putting (2) into (1), gives
2x = 52000
x = 52000/2 = 26000
From (2) and (3), we have
y + z = 26000 . . . (4)
42(26000) + 36y + 30z = 1960200
36y + 30z = 1960200 - 1092000
36y + 30z = 868200 . . . (5)
(4) * 30 => 30y + 30z = 780000 . . . (6)
(5) - (6) => 6y = 88200
y = 88200/6 = 14700
From (4), z = 26000 - 14700 = 11300
Therefore, there are 26,000 seats in section A, 14,700 seats in section B and 11,300 seats in section C.
Hi there!
We can begin by solving the inequality using the positive and negative terms:
3y - 1 > 5
Add 1 to both sides:
3y > 6
Divide both sides by 3:
y > 2
Now, solve the negative:
-(3y - 1) > 5
Distribute the -1:
-3y + 1 > 5
Subtract 1 from both sides:
-3y > 4
Divide both sides by -3. REMEMBER to flip the sign.
y < -4/3
'y' has to be LESS than -4/3 and greater than 2, so:
y < -4/3, y > 2
I don't have a line, but the answer is the payment of each visit is $76 in total, so you can subtract that from the $116 to get a monthly payment of $40.
Hope this Helps!
