15% = 15/100 = 0,15
36000•0,15=5400
12÷15<u /><em />=160
you have to divide 12 by 15 percent to get the missing number
10book=30mins
divide 10
1book=3mins
time=(time to read 1 book) times (number of books)
time to read 1 book=3 mins
15 books
15 books=15 times 3mins
15books=45mins
45 mins
Answer:
5:00 pm
Step-by-step explanation:
11:00 + 5 is 4.00 so you'd be a 4:40 + 20 minutes, that ranks up another hour so its at 5:00 pm
Multiply the first equation by -2 to eliminate a variable so it becomes:
-12x+8y=48
4x-8y=-32
Add them together.
-8x=16
x=-2
Plug it in one equation.
6(2)-4y=-24
12-4y=-24
-4y=-12
y=3
Ordered pair is: (-2,3)
