Answer:
$8.27
Step-by-step explanation:
First we need to find the tip. We know it was 18% of the total. So...
x (the variable we need to find) 18%
__ = ___
10.08 (the total bill including tip) 100%
cross multiply
100x = 181.44
-------------------- (divide by 100 to get x by itself)
100
x = 1.81 (The 18% tip that was given)
So now we know how much the tip was, we subtract it from the bill
10.08 - 1.81 = $8.27
Answer:
15.4z - 12
Step-by-step explanation:
Distribute:
=7.4z + (−5)(−1.6z) + (−5)(2.4)
=7.4z + 8z + −12
Combine Like Terms:
=7.4z + 8z + −12
=(7.4z+8z) + (−12)
=15.4z + −12
AB = 12
BC = 5
AC = 3
To find AC, we can use the pythagoras theorem, square root of 12 power of 2 + 5 power of 2 and we can get 12. Hope this help!
