1/2 = 3/6
Then you add 1/6
After that you do 6/6 minus 4/6 which then leads to the answer2/6
N = 3
Step-by-step explanation: If you do the equation it comes out to n=4
n+3n=12
4n=12
n=3
You have to add the like terms then divide it so the variable is by itself. And whatever you do to one side, you have to do to the other
Answer:
A) 2
Step-by-step explanation:
let 'a' = Angelica's age
let '6+2a' = Jacob's age
6+2a = 10
2a = 4
a = 2
Answer:
The answer is the seacond one on there
Answer:
86°
Step-by-step explanation:
If you draw a line segment AC, it forms the rest of right triangle ACB with the right angle at C. Then angle BAC is the complement of the given angle:
∠BAC = 90° -47° = 43°
The inscribed angle BAC intercepts arc BC, so the arc measure will be double the angle measure.
arc BC = 2·43° = 86°
__
Another way to get there is to realize that arc BCA is 180°, because AB is a diameter. As above, arc AC will be double the measure of inscribed angle ABC, so arc AC has measure 94°.
arc BC = arc ACB - arc AC
arc BC = 180° -94°
arc BC = 86°
