Answer:
Associative propertry of addition.
Step-by-step explanation:
The associative property of addition states that:

It states that we can add numbers regardless of the groups. The sum does not change irrespective of how the addends are grouped.
We are given the expression:

It can be written as:

It can also be written as:

Whatever maybe the arrangement of r, h and t, their sum will always be equal. We can regroup them in many ways but the sum remains the same.
1/2 x > 18.5
x > 37 is the answer
One solution
3(x-8)+14=2x-2
3x - 24 + 14= 2x - 2
3x - 10 = 2x - 2
3x = 2x + 8
3x - 2x = 8
1x = 8
First to get the equation you knew to understand one thing about perpendicular lines. The slope of the line is the opposite reciprocal of the perpendicular lines or the new slope is m = 10.
Then you use the formula
y = mx + b
you plug in your values from the point and the new slope.
(1,5) with new slope m
5= 10(1)+b
5-10=b
-5 = b
then make your new equation
y = 10x -5
that's your line that goes through point (1,5) and is perpendicular to the line given
