Y +6 =(1/2)(x+4)
y +6 = 1/2 x +2
y=1/2 x - 4
or 1/2 x -y = 4
By looking at the diagram, we see that angle C is 45 degrees, angle A is 90 degrees, and angle B is unknown
Given that the sum of all the triangle's angle is 180 degrees, angle B is also 45 degrees
This means that we have a 45-45-90 triangle, which has some special properties as shown in the diagram I uploaded.
Thus <u>BC in the simplest term is </u>
Hope that helps!

Answer:
13 nickels
Step-by-step explanation:
Let n represent the number of nickels Bob has. Then 18-n is the number of dimes, and the total value (in cents) is ...
5n +10(18-n) = 115
-5n +180 = 115 . . . simplify
65 = 5n . . . . . add 5n-115
13 = n . . . . . . . divide by 5
Bob has 13 nickels.
Answer:
20 games
Step-by-step explanation:
Lets work backwards; *Adding what he gave away or lost*
-Alex started with 16 video games
-Add the games gave to his brother (+2)
-Add the games he sold (+3)
-The number is 3/4 of his games
-Subtract the games he traded with hector (-1/4)
Equation: 16+2+3-6= 3/4 X (variable) *You can choose other than X*
21-6 = 15
15 = 3/4
Take the reciprical of 3/4 which is 4/3 and multiply it by both sides
4/3 x 15 = 3/4 x 4/3
4/3 X 15 = 20!
