12 groups, and each one containing 10. 
Think about it. Which operation could we use?

Multiplication!

12*10 = 120

Dave has 120 rocks. 

(One nice rock collection, Dave)

The sum of two positive numbers is 5 times their difference. What is the ratio of the larger number to the smaller number?
Anna11 [10]
Let the two numbers be x and y

x + y = 5(x-y)
x + y = 5x -5y
6y = 4x
x= (6/4)y
x= (3/2)y

there the ratio is 3/2

What Is the slope of the line on the graph?
sashaice [31]

Answer:

1/2

Step-by-step explanation:

To find out this problem, you do rise over run to find the slope. First choose two points that are directly sitting on a line. I used (-2,1) and (0,2). Then count the rise, up 1, then the run, over two and that's how you get your answer. :)

автобус прошел 220 км за 27/7 часа.Сколько километров пройдет автобус за 54/7часа с той же скоростью?
egoroff_w [7]

Отвечать:

440 км

Пошаговое объяснение:

Учитывая, что :

Пройденное расстояние за 27/7 часов = 220 км

Расстояние, которое необходимо преодолеть за 54/7 часов, составит x

Следовательно, мы можем настроить перекрестное умножение:

27/7 = 220

54/7 = х

Крест умножить

27/7 х = 220 * 54/7

27x / 7 = 11880/7

3.8571428x = 1697.1428

х = 1697,1428 / 3,8571428

х = 439,99999

x = 440 км

Таким образом, за 54/7 часов будет преодолено расстояние 440 км.
