0.05x+0.02(2000-x)=77.5
0.05x+40-0.02x=77.5
(0.05-0.02)x=77.5-40
0.03x=37.5
X=37.5/0.03=1250 at 2%
2000-1250=750 at 5%
She would need to ride her bike more than 10.33 miles per day: x > 10.33
She has 62 miles left to ride for the week. To find the average per day, we just need to divide that amount by 6.
Dividing will give us 10 and one-third, or about 10.33.
Add 5
5,10,15,20,25,30....
Step-by-step explanation:
1. draw the parallelogram with side 20cm and 25cm respectively and also the diagonal as well.
2.Clearly it forms a triangle in the parallelogram with three known lengths of side.
3.Using the cosine rule : c^2=b^2+c^2 -2bc cos c to find the obtuse angle.
