Answer: $107
Step-by-step explanation:
Tip = 20 % of $90
= 20/100 × $90
=$18
Sales tax at 10% = 10/100 × $90
= $9
Total cost= $90 + $18 + $9
= $107
The set is linearly dependent.
To explicitly prove this, we need to show there is at least one choice of constants
such that

or equivalently,

which is the same as solving the system of equations

From the first and last equations, we have
and
. Substituting these into the second equation leaves us with
, and so the overall solution set is

for which there are infinitely many not-all-zero solutions.
Answer: the answer is 10%
Step-by-step explanation: 1/10. You have to get the denominator to 100 so, you would x10 the debonair. You do the same to the top and get 10/100. So, 10%
Answer:
a.) 3x = 18 (where x = width)
b.) Area = 66 squared feet
Step-by-step explanation:
2{x + (2x-1)} = 34
3x - 1 = 17
x = 6 feet
length = 11 feet
Area = x (2x -1)
