Write 28 x 32 in associative property

Answers

Answer:

32 * 28

Step-by-step explanation:

Just flip the positions of the two and you have your answer

the associative property states that (in this case) changing the order of the numbers in the equation does not change the product. for example, "a" times "b" is equal to "b" times "a". this means 28 x 32 is equal to 32 x 28. so, 28 x 32 using the associative property is 32 x 28.

Answers

Answer:

if there can be no more than 5 students, then anything less than 5 students will suffice. However we don’t want any left over ones cause we don’t want that one kid sitting alone during lunch so we can simply put 4 into each group.

Answer:

6 groups, 4 students in each one

Step-by-step explanation:

The factors of 24 include 6 and 4

That means that you can break 24 into those numbers

You are able to put the students up into groups of 6, with 4 students in each

However, you cannot place the students into groups of 4 (with 6 students in each) because no more than 5 students are allowed in each group

How would you solve this problem? (Worth 10 points, pls help!)

Answers

Answer:

(22,0)

Step-by-step explanation:

1. Select any two points given and find their slope (rise/run)

       (-38, 40) and (-23, 30)

      slope =   [tex]\frac{40-30}{-38-(-23)}[/tex] = - 2/3

2. Use the slope and one of the points to create an equation of the line in the format y = mx + b, where m = slope and b = y-intercept.

    y = mx + b ⇒ 40 = -2/3 (-38) + b

3. Solve for b

   40 = -2/3 (-38) + b

   40 = 76/3 + b

   40 - 76/3 = b

   b = 44/3

4. To find the x-intercept, set y = 0, and solve.

   y = -2/3 x + 44/3

   0 = -2/3 x + 44/3

   2/3 x = 44/3

   x = 22

What is the equation of the line that passes through the point (8,-4) and has a slope of 3?

Answers

In order to solve it you insert the point in slope from

the equation is
Y=Mx+b

Plug it in as

-4=3(8)+b


-4=24+b

Then subtract 24

B=-28

So

The answer is

Y=3x-28
y-y1=m(x-x1)

(8, -4) 8 is x1 and -4 is y1
so y- (-4) = 3 (x -8)
make 4 a positive then y + 4 = 3x - 24
subtract 4 from 24 then y=3x-20

So looking at this from my bed, as a bored 11 year old, 2,910 is the rounded version of 2,912. Not to make you do work or anything but 2,910 divided by 95!

Answer:

Step-by-step explanation:

Here’s a way To solve :D

if she biked 95 each day, we just find how many days it’ll take.

2912/95=30.65 or 31 days if you want to use 31 I advise you to use 30.65

even though this seems improper, if you multiply 30.65 by 95 you’ll still get 2912

PLEASE HELP The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.

Answers

Answer:

You can use the method of substitution and elimination.

Team A : Team B

        3x : 2x

       -12   +12

        5y : 4y

3x-12=5y ---> (1)

2x+12=4y ---> (2)

12x-48=20y

10x+60=20y

12x-48=10x+60

12x-10x=48+60

           = 108

2x=108

x=54

Original number of athletes on Team A = 3(54)

                                                                  = 162

Original number of athletes on Team B = 2(54)

                                                                    = 108

3,6,9,12= 4
2,4,6,8,10,12= 6

So it is 4 and 6

Line segment AB has a length of 3 units. It is translated 2 units to the right on a coordinate plane to obtain line segment A prime B prime. What is the length of A prime B prime? (5 points)

1 unit
2 units
3 units
5 units

Answers

Answer:

The correct option is C.

Step-by-step explanation:

It is given that line segment AB has a length of 3 units. It is translated 2 units to the right on a coordinate plane to obtain line segment A'B'.

Translation is a rigid transformation. It means the shape and size of preimage and image are same. In other words we can say that the preimage and image are congruent.

Corresponding sides of congruent figures are congruent.

The length of A'B' is 3 units. Therefore the correct option is C.

the answer would be C/ unit 3 because the segment of AB has a length of 3
