Answer:
y = 218
Step-by-step explanation:
Mean = (Sum of all numbers)/(How many numbers present)
27 = (20 + 2y + 25 + y + 30)/27
27 = (3y + 75)/27
3y + 75 = 729
3y = 729 - 75
3y = 654
y = 218
Answer:
<u>6% sales tax</u>
Step-by-step explanation:
48 / 800 = x / 100
What did you do to turn 800 into 100? Divide by 8.
Since we divided the denominator by 8, we also divide the numerator by 8.
48 / 8 = 6
<u>6% sales tax</u>
(3x-12)+12(xy-10), x=4, y=6
(3(4)-12)+12((4)(6)-10)
(12-12)+12(24-10)
0+12(14)
12*14=168
