Answer:
44/5+3 2/10- 1 1/5= 44/5 + 3 1/5 - 11/5 = 44/5+ 16/5- 1 1/5 44/5+16/5-6/5 44/5+2 54/5=54/5 which equals 10 4/5 is your answer I hope this helped you! (;

Answer:
67 and -1
Step-by-step explanation:
You always multiply first so its 7+64-4 and that becomes 67
You have to distribute first so the problem would be 5-21+15 which is -1
Since the tip is 15% of some cost x, we can calculate that.
Remember to write the percent as a decimal for the calculations
Think of the tip as the question 2.40 is 15% of what number?
2.40/x = 15/100
Multiply both sides by x
2.40 = 15x/100
2.40 = 0.15x
So the tip 2.40 = 0.15x
Divide both sides 0.15 to solve for x
And that makes the cost before the tip 2.40/0.15 = 16.00
$16.00
The total bill for his lunch would be the cost before the tip plus the tip
We can calculate the final bill as $16.00 + $2.40 = $18.40
$24500 multiply by 27%= $6,615
There , $24500( initial price ) + $6,616= $31,115 ( as the new price).
Its the same as a square! you do base x height and for explaination just say if u split the parallelagram in half and put it together it makes a square!
