The total will be $19.72 with 20% so she will get back $30.28
The sum of known =179
The unknown = x
179+x/6=39
179+x =39*6
x = 234-179
1) 4n
The arithmetic sequence is going up in 4’s (1 x 4 = 4, 4 x 4 = 16)
Therefore the answer is just 4n
2) 0.5n (1/2n)
The arithmetic sequence is going up in 0.5’s (1 x 0.5 = 1/2, 1/2 x 0.5 = 1/4)
Therefore the answer is just 0.5n or if you need it in a fraction it is (1/2n)
3) -7n
The arithmetic sequence is going up in -7’s (7 x -7 = -14, -14 x -7 = 28)
Therefore the answer is just -7n
Answer:
? = 70°
Step-by-step explanation:
180 - 120 = 60° (120° and 60° are supplementary angles)
180 - 50 - 60 = 70° (all triangle interior angles total 180°)
Answer:
Yes
Step-by-step explanation:
Adding to both sides of the equation will keep both sides equal
