Answer:
p = 250 - 15(w)
Step-by-step explanation:
Original amount: 250
No of weeks to return money: w
Amount to pay each week: 15
Amount that he has paid back: 15 × w (When we subtract this term from the total we will get the answer)
So after w weeks he owes his parents :
p = 250 - 15(w)
Answer:
8 units ^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the length of the base and h is the height
b = LK = 4 units
h = J to where LK would be extended to, which would be 4 units
A = 1/2 (4) * 4
A = 8 units ^2
Answer:
12.8 is the speed of the boat
Step-by-step explanation:
64/5
If the perimeter is known / given and is 6x, you can find the length of the unknown side by adding up the lengths of the other two sides and subtracting this sum from 6x:
6x - (x+3 + 2x + 4) = 6x - x - 3 - 2x - 4
Combining like terms, 3x - 7 represents the length of the unknown 3rd side.<span />
Answer:
Perimeter = 180
Area = 1080
Step-by-step explanation:
Perimeter is length of all sides added together. 30+78+72 = 180
Area is the length times the height/2 for a triangle. 30*72/2 = 1080
I hope this helped <3
