Answer:
d/7 = c
Step-by-step explanation:
-5c+d=2c
Add 5c to each side
-5c+5c+d=2c+5c
d = 7c
Divide each side by 7
d/7 = 7c/7
d/7 = c
Answer:
10 degrees
Step-by-step explanation:
Answer:
mDF = 90°
(Assuming arc mCE is 5x + 10)
Step-by-step explanation:
When we have two chords crossing in a circle, there is a property where the angle in the cross point is equal half the sum of the corresponding arcs.
So in this case, we have:
70° = (mCE + mDF)/2
Assuming mCE is 5x + 10, we have:
70 = (5x + 10 + 11x + 2)/2
70 = (16x + 12)/2
70 = 8x + 6
8x = 64
x = 8
So the arc mDF is:
mDF = 11x + 2 = 11 * 8 + 2 = 90°
A+b=(-3n+2)+(5n-7)
=(5-3n)+(2-7)
=2n-5
Came up with the same answer as the first guy
The ratio of book price to number of pages for the ordered pairs a, b , and c are:
- <em>A = 0.05</em>
- <em>B = 0.05</em>
- <em>C = 0.043</em>
The ratio of book price to number of pages can be evaluated for each ordered pairs as follows;
Therefore, ratio of book price to number of pages for the ordered pairs a, b , and c are:
a = 0.05
b = 0.05
c = 0.043
