Answer:
Step-by-step explanation:
If lines OA and OC trisect angle NOD, then
By angle addition postulate:
If line OB bisects ange NOD, then
Angle AOB is 20 degrees less than angle NOA, then
By angle addition postulate,
Thus,
and
Answer:
y = -0.5x -2
Step-by-step explanation:
We have to find a line perpendicular to the line y = -2x -3.
Let the required line will have slope m so ,
-2m = 1
m = -0.5.
So, the required line will have the slope -0.5.
Now, let the line be y = -0.5x + c.
This line is passing through (-2,-1), So putting this point in the line we will get
-1 = 1 + c
c = -2 .
So, the required line is
y = -0.5x -2.
Simplify 3x × 2 to 6x
6x - x + 8y + 4x × 2 - 3x - 5y
Simplify 4x × 2 to 8x
6x - x + 8y + 8x - 3x - 5y
Simplify
<u>10x + 3y</u>
Answer:
6 items are being purchased
Step-by-step explanation:
Given that variable p represents the number of items being purchased, and the variable t represents the time required to ring up the customer, If it takes 44 seconds to ring up a customer then the number of items being purchased may be computed by substituting the value of t into the given equation
t = 4p + 20.
Using t = 44
44 = 4p + 20
collect like terms or subtract 20 from both sides
44 - 20 = 4p
24 = 4p
Divide both sides by 4
24/4 = p
p = 6
Answer:
The rate of sales tax is 6%.
Step-by-step explanation:
First you must subtract 12.50 from 13.25
This brings you to .75
Then, divide .75/12.50 to get 0.06 which is equivalent to 6 percent.
