Answer:

43/7

Step-by-step explanation:

6  1/7

First, you need to multiply 6 by 7, then add 1

43/7

Answer:

[tex]\frac{43}{7}[/tex]

Step-by-step explanation:

6 x 7 + 1

there is 6 whole fractions so it would be [tex]\frac{7}{7}[/tex] 6 times then add the [tex]\frac{1}{7}[/tex]

which would be [tex]\frac{43}{7}[/tex]

hopefully that made sense!

Answer:

Step-by-step explanation:

xy = 864

x + y = 60                     Solve for y in the second equation

y = 60 - x                      

x * (60 - x) = 864          Remove the brackets.

60x - x^2 = 864           Put in order of powers and subtract 864

-x^2 + 60x - 864 =0    Multiply through by -1

x^2 - 60x + 864 = 0

This factors

(x - 36)(x - 24) = 0

Either

x - 36 = 0    in which case

x = 36

or

x - 24 = 0

x = 24

The two numbers are x = 36 and y = 24

of x = 24 and y = 36

Answer:

Step-by-step explanation:

Number of people who entered the drawing = 10

Number of prizes = 3

Number of ways to award the prize = 720 ways

The total number of ways that 3 prizes can be awarded to the 10 people can be determined as:

10*9*8 = 720

The total number of ways in which I win the first prize and my mom wins the second prize would be 1*1*8 = 8

Thus the probability that I win the first prize and my mom wins the second prize would be 8/720

Answer:

8-(-10)=-8+10=8 your answer is 8

Step-by-step explanation:

Depending on if the x and/or y are positive or negative will depend on were the dots will be placed on the graph.

Places the points are simple.

X is across, Y is up and down.

Example,

If you need to plot (4, 3)

You will need to start at the center point (0,0)

You must go over to the right 4 places, and go up 3 places. That is the easiest way to graph.

Labeling,

It will kind of be the same way. Find out how many places the point is from the (0,0) on the x axis, and y axis.

Answer:

8

Step-by-step explanation:

if it's saying that 32/52 is equal to x/13, then we know that 32/52 is divisible by the mystery fraction.

since both fractions have a denominator, divide them.

52÷13=4

then, divide the answer, 4, by 32.

32÷4=8.

therefore, your answer is 8.

hope this helps!

Answer:

8

Step-by-step explanation:

A trick with equal fractions will be that the cross multiply will create equal answers

13(32) = 52(?)

To find the missing number, just divide the known product by the missing number's multiplicand.

? = 13(32)/52 = 8

To verify

13(32) = 416

52(8) = 416

Yup!

My answer would be 66

The LCM of 22 and 33, using prime factorization, is 66.

A number system is defined as a system of writing to express numbers.

We have to find LCM of 22 and 33 using prime factorization

Factor each term into prime factors

22 = 2 x 11

33 = 3 x 11

Identify all of the unique prime factors of these two numbers.

Finally, we can find the LCM by multiplying each of these prime factors raised to their highest power that appears in either of the two factorizations.

LCM(22, 33) = 2x 3 x 11

LCM(22, 33) = 66

Therefore, the LCM of 22 and 33, using prime factorization, is 66.

Answer:

115 square yards

Step-by-step explanation:

yeah-ya....... right?

The area of the figure is 115 yd².

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

A figure:

This can be assumed to have two rectangles and one square.

Two rectangles are equal with dimensions:
Length = 9 yd

Width = 5 yd

The square has side = 5 yd.

Now,

Area of the figure.

= 2 x area of rectangle + area of the square

= 2 x (length x width) + side²

= 2 x (9 x 5) + 5²

= 2 x 45 + 25

= 90 + 25

= 115 yd²

Thus,

The area is 115 yd².
