Write a question about 7 ones and 8 groups of 10

1 answer:

4 0

There are 7 marbles laying across the ground, you decide to pick them up so that they don't become a problem later. Afterwards, you find that your friend has made it into a competition to see who can get the most marbles. Both of you get 40 marbles each, this means there is a total of 8 groups of 10 marbles, and 7 groups of individual marbles. You then rejoice, as the marble minefield is now gone.

Graph the solution to the following system of inequalities in the coordinate plane.

Answer:

see below

Step-by-step explanation:

The first equation is in slope-intercept form, so you can see that the boundary line has a slope of -2 and goes through the point (x, y) = (0, -4). Since the comparison is "<", the line is dashed and shading is below it.

The second equation is that of a vertical boundary line at x=-3. It is solid, because the comparison includes the "equal" case. Shading is to the right of it, where x values are greater than -3.

Answer:

144 cookies

Step-by-step explanation:

Answer:

Her daughters age: 1/2x

Step-by-step explanation:

Let's say Rani's present age is x. Her age is twice the age of her daughter.

So if Rani's age is 20, her daughters age would be 10, because Rani is twice the age of 10; so 10 times 2 would be 20.

1/2(20)=daughter's age

so if you substitute x into 20 because we don't actually know Rani's age, it would be 1/2(x)=daughter's age.

hope this helped :-) <3

The line a bus arrives at the bus stop every 25 minutes, and the line b bus arrives every 15 minutes.Both are at the stop right

Answer:

after 75 minutes

Step-by-step explanation:

The least common multiple (LCM) of 15 and 25 is 75. It can be found a couple of ways:

1. List the factors of each number and find the product of the unique ones:

15 = 3·5

25 = 5²

The LCM is 3·5² = 75.

2. Find the greatest common divisor (GCD) and divide the product of the numbers by that value. From the above list of factors, we see that 5 is the GCD of 15 and 25. Then the LCM is ...

15·25/5 = 75

Or, you can simply list multiples of each number and see what the smallest number is that is in both lists:

15, 30, 45, 60, <em>75</em>, 90

25, 50, <em>75</em>, 100

The two buses will appear together again after 75 minutes.
