Answer:
8x +4y
Step-by-step explanation:
6x + 3y + 2x + y
1) add similar variables together.
2) 6x + 2x = 8x
3y + (1)y = 4y.
3) y by itself basically means 1y, since in front of every variable theres an invisible 1.
So, a full circle has 360°, thus when the minute hand does one hour, it does a full circle, therefore 360°.
now, how many degrees are there in 1 minute? well, there are 60 minutes in 360°, therefore there are 360/60 degrees in 1 minute, or 6°.
now, we know in 1 hour there are 360°, how many in 27 minutes? well, 27 * 6, or 162°. So after 1hr and 27min, the minute hand has done 360+162 or 522°.
we also know the minute hand is 2 inches long, thus

which is roughly 18 inches rounded up.
Answer:
The horizontal line is the x-axis and the vertical line is the y-axis.
Step-by-step explanation:
The horizontal line is the x-axis and the vertical line is the y-axis. It's a fact. You can graph the lines by inserting the equations using the graphing calculator, which is the tab next to the one you have right now ;)
Step-by-step explanation:
13.70 square inches of the box is empty
Your answer would be 29
Why?
Because that is a right angle. They always have to be 90° so 90-61=29
