Answer:
so to solve an inequality you just treat the inequaltity sign like an equals sign except if you multiply by negative 1 you flip the direction of the sign.
p-7/12>3/10
add 7/12 to both sides
p>7/12+3/10
p>35/60+18/60
p>53/60
so if you had to graph this on a number line you would have an open circle on 53/60 and an arrow coming off pointing to the right

Answer:
C) x = y - 6
Step-by-step explanation:
you have to make it in terms of x, or isolate x:
y = x + 6
- 6 from both sides
y - 6 = x + 6 - 6
combine 6 and -6
y - 6 = x
so, x = y - 6
Answer:
Basically this is because division can be thought of as how many times does the divisor have to be multiplied in order to produce the dividend.
So you would need to multiply 1 8 times in order to produce the dividend,
Similarly, 10 goes into 80 8 times. The zeros are simply cancelled out in the division.
Statement : If the perpendicular bisectors of two sides of a triangle meet at point that belongs to the third side then this is a right angle triangle.
Prove:
Let ABC is triangle,
In which DF and EF are the perpendicular bisectors of legs AB and BC respectively.
That is, ∠ FDB = ∠BEF= 90°
Where, 
Then By the property of the circumcenter,
F must be mid point of leg AC.
That is, DF ║ BC
⇒ ∠ FDB + ∠ DBC = 180° ( the sum of two adjacent angles on the parallel lines by the same transversal is supplementary )
But, ∠ FDB = 90°
⇒∠ DBC = 90°
⇒ ∠ ABC = 90°
That is, Δ ABC is a right angle triangle.
