Answer:Angle A is equal to 113
Step-by-step explanation:
If two angles are vertical, that would make them equal to each other.
7x-20=6x-1
Add on to both sides
7x-19=6x
Subtract Seven from both sides
-19=-x
Divide by negative one to get rid of the negative
19=x
Then plug x into the equation 7(19)-20
Answer: $31.99
Step-by-step explanation:
So, it is originally $39.99, so first we convert 20% to a decimal, which is 0.2.
Then we do 39.99 * 0.2 to find how much money was taken off.
39.99 * 0.2 = 7.998, or $8
Now, we do the original dollar amount, $39.99, minus the discount, $8, which equals $31.99.
