Answer:
v= 17
Step-by-step explanation:
Start with the given equation.
19v – 18 = 16 + 17v
Move -18 to the other side, and swap it's sign.
19v = 16 + 18 + 17v
Move 17v to the other side and swap it's sign.
19v - 17v = 16 + 18
Combine like terms.
2v = 34
Divide by 2v.
v = 17
Greatest integer function returns the largest integer values less than or equal to that number
for example : [7.7] = 7
[2.6] = 2
[-6.3] = -7
We round the number to the nearest whole number less than the given number
Evaluate [4.8]
[4.8] = 4 , nearest whole number less than 4.8 is 4
Evaluate [-2.7]
[-2.7] = -3, nearest whole number less than -2.7 is -3
$815
14(500*0.045) + 500
= 14(22.5) + 500
= 315 + 500
= 815
Answer:
$32.80
Step-by-step explanation:
Let f be the cost of a file, then a storybook costs 3f ( 3 times as much )
Then the difference in cost is
3f - f = 16.40, that is
2f = 16.40 ( divide both sides by 2 )
f = 8.20
The cost of a file is $8.20 and the cost of a storybook is 3 × $8.20 = $24.60
The total cost of the 2 items = $8.20 + $24.60 = $32.80
