Answer:
N
Step-by-step explanation:
The II and III quadrant are all negative x values, and the I and II quadrants are all positive y values!
685-85=600
1 year =12 months
12 multiply by 2 =24
600 divided by 24=25
answer=25
Answer:
There are 21 twenties and 8 fifties in the drawer.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of twenties
y is the number of fifties.
A cash drawer contains 29 bills.
This means that x + y = 29.
The total value of the bills is $820.
This means that 20x + 50y = 820.
So
x + y = 29
20x + 50y = 820
From the first equation, x = 29 - y. So:
20x + 50y = 820
20(29 - y) + 50y = 820
580 - 20y + 50y = 820
30y = 240
y = 8
And
x = 29 - y = 29 - 8 = 21
There are 21 twenties and 8 fifties.
Answer:
z = 6
Step-by-step explanation:
sin (9z - 1) = cos (6z + 1)
90 - (9z - 1) = 6z + 1
90 - 9z + 1 = 6z + 1
9z + 6z = 90
15z = 90
z = 6
