21x-9+63=180
21x+54=180
21x=126
x=6
Either a or b. C and d don’t make sense cuz there’s no way those lines are perpendicular
Answer:
B
Step-by-step explanation:
The two variables are time and day. The columns are similar because the two middle times are the most popular and the two outside times have less people. This shows a relationship
Answer:
The angles are 54 2/3 degrees and 115 1/3 degrees
Step-by-step explanation:
make an equation for the angles x being one angle and y being the other
16+ 2x =y
Supplementary angles add to 180
x + y = 180
Fill in y with the first equation
x + 16 +2x =180
simplify
3x +16 =180
subtract 16 from both sides
3x = 164
divide both sides by 3
x = 54 2/3
Insert the value of x into the first equation then simplify
16 + 2(54 2/3) =y
16 + 109 1/3 =y
115 1/3 =y
Answer:
The tax itself is $19.25.
Step-by-step explanation:
0.06 * 320.90 = 19.254
If you want the cost + tax, it is 320.90 + 19.25 = 340.15
