Simplest way would be to find out how many painting more it would be 80 from 20. It is four times more drawings. Now since you know it is 4x more then you can simply multiply 4 time 4 (4*4) because it would be the weeks it takes him by the times it would be. It would be 16 weeks in total.
Answer: k = 55 degrees
Step-by-step explanation:
to find J, subtract 122 from 180, you get 58. The total number of degrees is 180. Since L is given as 67, and 67+58=125. Simply subtract 125 from 180 which is 55 degrees
I would use elimination
2x+3y = 7
2x-y = -5
Subtract those equations
4y = 12
Y = 3
Now plug in 3 for any y value
2x - 3 = -5
2x = -2
X = -1, y = 3
What are the answer choices ?
