Let the number of weeks to have same amount = x Then:-
1200 + 40x = 700 + 50x
1200 - 700 = 50x - 40x
10x = 500
x = 50
answer is 50 weeks
150 and the unknown angle next to it equal 180.
180 - 150= unknown angle
30 degrees= unknown angle
Then the triangle also equals 180 so we add the angles and solve for x
3x + 2x + 30= 180
5x + 30= 180
5x= 150
x= 30
3x= 3(30)= 90 degrees
2x= 2(30)= 60 degrees
Answer: d) x+y =40
x=2y -11
