"The
segment connecting the midpoints of two sides of a triangle is parallel to the
third side and equals its half length"
so that:
(x-3)=0.5(2+x)
solve for x:
x=8

Answer: 26.55°C
Step-by-step explanation:
Average daily maximum temperature in Syracuse = 21.85°C
Average daily minimum temperature = -4.7°C
In order to solve the question, we calculate the difference between the two temperature given. This will be:
= 21.85°C - (-4.7°C)
= 21.85°C + 4.7°C
= 26.55°C
Answer:
0.15x=x-30
Step-by-step explanation:
Let
x-----> the regular price
we know that
15%=15/100=0.15
so
0.15x=30
x=30/0.15=$200
<em>Verify each case</em>
case a) 0.15x=30
x=30/0.15=$200
therefore
The equation could be used to determine x
case b) 0.85x=x-30
x-0.85x=30
0.15x=30
x=30/0.15=$200
therefore
The equation could be used to determine x
case c) 0.15x=x-30
x-0.15x=30
0.85x=30
x=30/0.85=$35.29
therefore
The equation could not be used to determine x
case d) x-0.15x=x-30
-0.15x=-30
0.15x=30
x=30/0.15=$200
therefore
The equation could be used to determine x
