Answer:
it is definitely $60 . Do not count the expenditure cause it is not asked .
1. B
∠1 and ∠3 are corresponding angles where a transversal (line r) cuts two parallel lines (p and q).
2. C
Each of the segments of ABC is twice the length of the corresponding segment of EDF. Hence the perimeter of ABC is twice that of EDF.
THE ANSWER IS x € (0,4)
First we separate this into two inequalities:
2x-3>-3
2x-3>-32x-3<5
Now we solve the inequalities:
2x-3>-3
2x>0
x>0
2x-3<5
2x<8
x<4
x € (0,4)
The answer is 1000 ft, 800 ft, 600 ft.
Let:
a - the longest side
b - the middle side
c - the shortest side
The <span>perimeter of a triangular plot of land is 2400 ft: P = 2400 ft
The perimeter of a triangle is P = a + b + c, thus a + b + c = 2400
</span><span>The longest feet (a) is 200 ft less than twice the shortest (c): a = 2c - 200
</span><span>The middle side (b) is 200 ft less than the longest side (a): b = a - 200
Now, we have the system of three equations:
</span>a + b + c = 2400
a = 2c - 200
b = a - 200
__________
Substitute a from the second equation into the third equation:
b = 2c - 200 - 200 = 2c - 400
__________
Substitute a and b into the first equation:
(2c - 200) + (2c - 400) + c = 2400
2c - 200 + 2c - 400 + c = 2400
2c + 2c + c - 200 - 400 = 2400
5c - 600 = 2400
5c = 2400 + 600
5c = 3000
c = 3000/5
c = 600 ft
_________
Now, use c and substitute into the second and third equation:
a = 2c - 200
a = 2 * 600 - 200
a = 1200 - 200
a = 1000 ft
___
b = a - 200
b = 1000 - 200
b = 800 ft
