4n=c because if you new how many books Kira bought you would multiply that by the cost of one notebook, $4*notebook(s), which would then equal the cost.
the perimeter of a semi circle whose radius is the perimeter of a semi circle whose radius is the perimeter
Answer:
The y-intercept is -2 and the equation is y=x-2
Step-by-step explanation:
-That's where the line crosses the y axis.
-The equation is y= x -2 because it has a rise/run of 1/1 which is just 1 and the y intercept is -2
( I'm so sorry I totally missed the second part of the question lol)
1/3 is greater. 4/10 is 40%, 3/5 is 60%, and 5/20 is 25%. For 5/10 the benchmark would 1/2. For the graph of 31/50 it would 69/100. And for the last one it would just be 4/5 I believe (I’m not sure about the last one)
Hope this helps tho:)
Using subUsing substitution for Y, the top equation becomes X +6z= 180. Using elimination with X +6z= 180 and subtracting X+z= 90 result is 5z=90 and Z= 18. So complimentary angle is 18°
