Answer:
624
Step-by-step explanation:
the width is 104
if the length is doubled, that means the length is 208.
rectangles have 2 sets of equal sides
104 + 104 =208
208 + 208 = 416
416+208 = 624
B=books
Sold half of book: b/2
Bought six more: b/2+
Now has 12: b/2+6=12
Subtract 6 on both sides: b/2+6-6=12-6
b/2=6
Multiply both sides by 2: b=12
Answer= 12 books
Answer:
3(2x+5)=3 6x+15 = 3 6x = -12 x =-2
9+9x=2x+2 9x-2x= 2-9 7x= -7 x=-1
Step-by-step explanation:
Answer:
350 miles
Step-by-step explanation:
Let x represent the miles driven
The cost with the first plan will be represented by 0.40x + 70
The second plan will be represented by 0.60x
Set these 2 expressions equal to each other and solve for x:
0.40x + 70 = 0.60x
70 = 0.20x
350 = x
So, Susan will have to drive 350 miles for the cost to be the same
Answer:
654000 Rupees
Step-by-step explanation:
If we assume that the opera house was full every day then it would be 872 x 50 for the price of 1 day
872 x 50 = 43600
We multiple that number by the amount of days open so is would be 43600 x 15
43600 x 15 = 654000
Therefore it will make 654000 Rupees
