If $2397 is 100%
and $685 is unknown
685x100=68500
68500/2397=28.5774
round to 29%
Answer:
it will always be equals to -1
Step-by-step explanation:
2 x - 1/2 = -1
17 x - 1/17 = -1
Here is the equation you should use: x + 2x - 12 = 180
You will be solving for x.
Combine like terms then add twelve to both sides of the equation.
3x = 192
Divide by 3 on both sides of the equation.
x = 64
Now, plug 64 in the equation for x.
2(64) - 12 = 116
Answer: Ashley spent $18.70 and the friend spent $17.16
Step-by-step explanation:
Original cost of Ashley's meal = $ 15.85
tip left = 18% of 15.85
that is
tip left = 0.18 x 15.85 = $2.85
All together, Ashley will pay
$15.85 + $2.85
= $18.70
The friend's original cost = $14.30
tip = 20% of 14.30
= 0.20 x 14.30
= $2.86
All together , the friend will pay
$14.30 + $2.86
=$17.16
Therefore:
Ashley spent $18.70 and the friend spent $17.16
No because if you change them in to the same denominator like 12 you would see for example. 3/4 = 9/12 and 5/6 = 10/12.
