Step-by-step explanation:
BDC and ACD are complementary with each other. that means together they cover the full 180 degrees of the half circle that can be drawn on one side of a flat line.
180 = 11x + 25 + 4x + 5 = 15x + 30
150 = 15x
x = 10
BDC = 11x + 25 = 11×10 + 25 = 110 + 25 = 135 degrees
ACD = 4x + 5 = 4×10 + 5 = 40 + 5 = 45 degrees
Answer:
1. algebraic expression: a mathematical expression containing one or more variables
2. coefficient: the constant preceding the variables in a product
3. constant: a numerical value
4. expression: a mathematical phrase that cannot be determined true or false
5. variable: a letter or symbol used to represent an unknown
Step-by-step explanation:
It is 14.8 I hope this helps you on your hw lol have a nice day
7+ 6

k
that's what it would look like if you wrote it out on paper
or you could type it like 7+(6/k)
hope it helps :)

Answer: Yes we have a direct proportional relationship</h3><h3>constant of proportionality = 8</h3>
equation is y = 8x
=============================================
Explanation:
Divide each x and y pair like so: y/x
If we get the same result each time, then we have a direct proportion.
y/x = 32/4 = 8
y/x = 56/7 = 8
y/x = 96/12 = 8
Each time we get the same result 8, which is the constant of proportionality. The table does show a direct proportional relationship. The equation is y = 8x which is in the form y = kx. The k value is the constant of proportionality. So k = y/x.
