Let x be the number of rows.
We solve the equation: x * ( 2 + 3 ) = 150.
x * 5 = 150.
x = 150 ÷ 5 .
x = 30.
a. There are 2 * 30 = 60 seats on the left side of the plane.
b. There are 3 * 30 = 90 seats on the right side of the plane.
Answer:
-64
Step-by-step explanation:
f(x)=-4^x
f(3)=-4^3=-64
Answer:
It's A.
Step-by-step explanation:
B doesn't make sense because you have to rotate the figure to get it on it's side, and there is no rotation involved.
C doesn't make sense because there's a reflection AND a scale factor of 2.
D doesn't make sense because there's a scale factor of 2.
A makes sense because a scale factor of 1/2 halves the size and the rotation lands it in the corresponding place.
Answer:
1. x = -7
2. y = -1
Step-by-step explanation:
1.
-3x - 5 = 16 add 5 to both sides
-3x = 21 divide -3 to both sides
x = -7
2.
-4(y-2) = 12 distribute -4
-4y + 8 = 12 subtract 8 from both sides
-4y = 4 divide -4 to both sides
y = -1

1. x = 9
2. y = -3
Answer:
3/5
Step-by-step explanation:
There are 12 window seats and 8 aisle seats giving us a total of 20 seats.
12/20 = 3/5
Therefore, the probably the next person will be assigned a window seat is 3/5.
