Answer:
(45 - 25) / 2 × (2 + 3)
Step-by-step explanation:
Given:
45 - 25/2 × 2 + 3
By trials:
(45 - 25) / (2 × 2) + 3
= 20/4 + 3
= 20/7
Another trial:
(45 - 25)/2 × (2 + 3)
= 20/2 × 5
= 20/10
= 2
The parentheses should be inserted like this
(45 - 25) / 2 × (2 + 3)
Multiply 80km by 9%
80km × 9% = 7.2 ←
80km is 9% of 7.2 ←
I hope this helps!

Thank you for describing the triangle. If you examine the figure you described, you'll realize that triangles MNO and QPO are similar triangles, with triangle QPO being half the size of triangle MNO. You can see this because both triangles have QOP as one of their angles and line segment PO is half the length of line segment NO as evidenced by the double tick marks on each side of the bisector P. Additionally, you can see that line segment QO is half the length of line segment MO as evidenced by point Q being the bisector of MO with the single tick mark on both sides of the bisector. So the length of PQ is half of the length of MN. And 14.4/2 = 7.2</span>
1. It will take 60 days for it to grow to 4 feet
0.6×60+12=48
48÷12=4
