Olivia has 48 slices of ham and 36 slices of cheese to make sandwiches.
serious [3.7K]

The greatest number of sandwiches that Olivia can make is 12.

3 slices of cheese will be on each sandwich

<u>Solution:</u>

Given that, Olivia has 48 slices of ham and 36 slices of cheese to make sandwiches.  

We have to find what is the greatest number of sandwiches that Olivia can make? And how many slices of cheese will be on each sandwich?

Let the number of sandwiches be "n"

Then, number of slices of ham per sandwich =\frac{48}{n}

And, number of slices of cheese per sandwich =\frac{36}{n}

As slices can’t be fractions, "n" should be a factor of 48 and 36. So now let us find H.C.F of 48 and 36 as we want greatest number of sandwiches that Olivia can make.

The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48

The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, and 36

The common factors are those which appear on both factors of 48 and 36 are 1, 2, 4, 6, and 12.

Out of these common factors, 12 is the greatest

So, H.C.F of 48 and 36 is 12, which means n = 12

Then, number of cheese slices per sandwich =\frac{36}{12}=3

Hence, 12 sandwiches can be made with 3 slices of cheese per sandwich.

Draw a rectangle with an area of 42 square units
Butoxors [25]
We know, Area = Length * Width

So, with area 42, dimensions could be: 1 * 42
2 * 21
3 * 14
6 * 7

Just draw the lines with that measures, two pair of two equal opposite lines.

Hope this helps!

Which of the following is a solution to the equation "y=3x-1"
nalin [4]

we have

y=3x-1

we know that

If the point is an equation solution, it must satisfy the equation.

<u>case a</u>) (4,1)

Substitute the values of x and y in the equation

1=3*4-1

1=12-1

1\neq11 -------> the point is not solution of the equation

<u>case b</u>) (2,5)

Substitute the values of x and y in the equation

5=3*2-1

5=6-1

5=5 -------> the point is solution of the equation

<u>case c</u>) (4,3)

Substitute the values of x and y in the equation

3=3*4-1

3=12-1

3\neq11 -------> the point is not solution of the equation

<u>case d</u>) (0,-3)

Substitute the values of x and y in the equation

-3=3*0-1

-3\neq-1 -------> the point is not solution of the equation

therefore

<u>the answer is</u>

The point (2,5) is solution of the equation
