Take the amount of rows in the auditorium, 15, and multiply that by the number of new seats in each row, 3. You get 45. Now multiply the number of new seats, 45, by the cost of each seat, $74. You get $3,330.
Answer:
y= -(3/2)x -5
Step-by-step explanation:
Divide both sides by negative 2
-2y=3x+10
This halves the 3 and the 10 resulting in (3/2) and 5 values, since they are positive integers dicided by a negative integer they become negative. Negative 2 divided by begative two becomes positive 1 since negatives cancel each other out.
y= -(3/2)x -5
Answer:
12
Step-by-step explanation:
In this question, there are two variables: the number of mangoes(y) bought and the number of oranges bought(x).
Let's say the man have z money, mangoes price is 
z and the oranges price is 
z. The equation for money and number of mangoes and oranges will be:
money = mango price * mangoes bought + orange price * orange bought
z= z * x + z *y
1= x +y
-y= x -1
y= -1.5x + 30
y= 30 - 1.5x
If he want equal number of mango and orange, that mean y=x. The calculation will be:
y= 30 - 1.5x
x= 30 - 1.5x
x+ 1.5x = 30
2.5x= 30
x= 
= 12
I think the answer would be 8 but I'm not sure
The 3rd choice is the right answer here
Hope this helps :)
Have a wonderful day !
