Answer:
m∠ABC = 83°
Step-by-step explanation:
The angle ∠abc and ∠dbe are opposed by the vertex. By definition "<em>Two angles opposite the vertex are congruent or equal</em>"
So ∠abc = ∠dbe
Then, to solve this problem you must match both expressions and clear the variable x.

Now substitute x = 15 in the given expression for the angle ∠abc. (6x-7)
So, we have:
°
Finally, the angle is 83°
Answer:
y-6 = -7x + 21
Step-by-step explanation:
Find the slope
(-8 - 6)/(5-3)
-14/2 = -7
Now find the formula
y-6=-7(x - 3)
y-6 = -7x + 21
Another way to write it is
y= -7x + 27
Answer:
The selling price is $30.80
Step-by-step explanation:
Buying price = $28.00
Rick applies a mark up of 10%
The percentage of buying price is 100%
The percentage of selling price is 100% + 10% = 110%
So $28 = 100%
What about 110%?
Cross multiplying gives;
110/100 × $28 = $30.80
The selling price is $30.80
