3x -1/2y = -7/2
x = -2y + 1
3 (-2y + 1) -1/2y = -7/2
-6y +3 -1/2y = -7/2
-13/2y = -13/2
y = 1
x = -2(1) + 1
x = -1
Answer = (-1, 1)
The answer is D, Cavalieri's Principle
Answer:
7/16 mile
Step-by-step explanation:
Distance of the loop = 7/8 mile
Distance of Water fountain = 1/2 of the Distance of the loop
= 1/2 of 7/8
Ibrahim stopped to get a drink of water at the water fountain. How far did Ibrahim run?
= 1/2 of 7/8
= 1/2 * 7/8
= (1 * 7) / (2 * 8)
= 7/16
Ibrahim ran 7/16 mile to drink water at the water fountain around the loop
supplementary angles = 180 degrees
so x = angle 1
y = angle 2
y = 3x-12
x + 3x-12 =180
4x-12 = 180
4x = 192
x = 192/4 = 48
y = 3(48) -12 = 144-12 = 132
132 +48 = 180
the angle is 132
We are given
first term is 1
so, 
each succeeding term is found by adding 3 to the one before it
so, common difference is
Since, this is arithematic sequence
so, we can use nth terms formula
now, we can plug values
and we get
