Answer: 10
Step-by-step explanation:
Answer: W = 112 carats
Step-by-step explanation: Let W be the original weight.
So we have
W - 45 = 67 add 45 to both sides
And that equals 112 carats
Answer:
Larger angle: 104 degrees
Smaller angle: 76 degrees
Step-by-step explanation:
(9x+5) + (6x+10) = 180
x = 11
Let's equate the congruent sides.

Now, the segment EF is equal to the segment CD:
Let's write x as our age and our cost as y -
If x≤5 , y=0
If 5<x≤12, y=10
If 12<x≤18, y=25
If x>18, y=35
It should be pretty straightforward to graph from there, but please ask if you're having any issues!
