Answer:
83.07
Step-by-step explanation:
If you multiple the original price $78 times the sale tax in decimal form 0.065 you get 5.07, $78 + $5.07 = 83.07.
Vertical angles i believe is the right answer to this problem
A would be "Because <2 is congruent to <4"
B would be "Definition of Supplementary Angles"
C would be "Subtraction Property"
These are a start, try to come up with them with the help of this
Answer:
X = 3
Y = 100
Step-by-step explanation:
The best way to solve equations like this is to plug & chug.
First, choose an equation and replace the Y variables with the y=... equation
Y = 30x + 10
(20x + 40) = 30x + 10
Then isolate the variable by subtracting 10 and 20x from both sides
40 - 10 = 30x - 20x
30 = 10x Divide by 10
3 = x
Y is much simpler; Plug x = 3 into one or both equations, plugging it into both will check your answer.
y = 20(3)+40
y = 60 + 40
y = 100
To double check math plug both variables into the other equation.
100 = 30(3) + 1=
100 = 90 +10
100 = 100
Answer:
6
Step-by-step explanation:
diagonals bisect each other in rectangle
