Answer:
x=4
Step-by-step explanation:
First set the equation equal to 4:
-2x +12=4
Subtract 12 from both sides:
-2x +12=4
-12 -12
-2x=-8
Then divide each side by -2 to isolate the x:
-2x/-2=-8/-2
x=4
Using the intersecting chord theorem:
15 x 2 = 5 x n
Simplify:
30 = 5n
Divide both sides by 5:
n = 30/5
n = 6 m
8 x n+8 = 16 x n+2
Simplify:
8n +64 = 16n +32
Subtract 8n from both sides:
64 = 8n +32
Subtract 32 from both sides:
32 = 8n
Divide both sides by 8:
n = 32 /8
n = 4
25%=25 candies
100 divided by 25=4
25*4=100 candies
100%=100 candies
Answer:
1/2, 4/5, 9/10
Step-by-step explanation:
Answer:

Step-by-step explanation:

Distribute 4(x+2).

Subtract 2x and 8 from both sides.


Divide both sides of the equation by 2.
