Answer:

y= 2.5

x= 3

Step-by-step explanation:

multiply eqn 2 by 5

5x +20y =65

eqn 2 -1

20-2)y=65-20

18y=45

y=2.5

x+4×2.5 =13

x+10=13

x=3

Plz help me with this I don't have my protractor with me plz help and do this
My name is Ann [436]
An acute angle is an angle less than 90 degrees. (smaller angle)
A right angle is exactly 90 degrees. (right angle)
An obtuse angle is over 90 degrees. (larger angle)
A reflex angle is any angle of 180 degrees. (largest angle)

You wouldn't *really* need a protractor to complete your homework; you could guesstimate.

I hope this helps!

-3x + 5y = 30<br><br> FIND THE x- SLOPE!!!<br><br> PLEASE HELP!!!
max2010maxim [7]
The slope would be 3/5 because you add 3X to 30 to cancel it out and get the Y by itself. Then you have to divide by 5 to completely isolate the Y. Since 3 is not divisible by 5 you are left with 3/5 as your slope.
