Answer:
Step-by-step explanation:
According to the midsegment theorem, the length of each side of the formed triangle is the half the parallel side of DEF.
<u>So the perimeter is:</u>
- P = 1/2(12 + 16 + 20) = 24
Answer:
x = 49 mi/hr
y = 6 mi/hr
Step-by-step explanation:
A motorboat travels 258mi in 6 hours going upstream. It travels 330mi going downstream in same amount of time. What's the rate of the boat in still water and what is the rate of the current.
Let
x = the speed of the boat in still water.
y = the speed of the stream
The speed upstream is x - y
The speed downstream is x + y
Distance = rate × time
258 = (x - y)6 (1)
330 = (x + y)6 (2)
From (1)
x - y = 43 (3)
From (2)
x + y = 55 (4)
x - y = 43 (3)
x + y = 55 (4)
Add the equations to eliminate y
x + x = 43 + 55
2x = 98
x = 98/2
x = 49 mi/hr
Substitute x = 49 into (4)
x + y = 55 (4)
49 + y = 55
y = 55 - 49
y = 6 mi/hr
Answer:
well dependes on how u need them
when a negative and negattive are next to eachother
3- (-6) this 3+6 becomes a positive
you also have where 2 negatives make a positive
a positive plus a negative will give you positive. same as times them.
negative minus negative equals negative, negative minus positive equals positive.
hope it helps
