Answer:
11.5 kg
Step-by-step explanation:
Is means equals and of means multiply
50% * 23 = W
Change to decimal form
.50 * 23 =W
11.5 = W
Answer:
Mid-point: 
Equation: 
Step-by-step explanation:
To find the mid-point of AB, simply add up their x and y coordinates and divide by 2 respectively to find their middle point.



To find the perpendicular slope that passes through the mid-point, we need to know the slope between AB first.
Slope of AB:
=
=
= 
Multiplying slopes that are perpendicular with each other always results in -1.


By the point slope form:

Plug in the coordinates of the mid-point:

Equation: 
Answer:
12a - 6b
Step-by-step explanation:
Given
8a + 3b + 4a - 9b ← collect like terms
= (8a + 4b) + (3b - 9b)
= 12a + (- 6b)
= 12a - 6b
