Explain the relationship between a strategy, such as number sense, and a written method , such as partial products or area models , for multiplying decimal number's.

Answers

Answer 1

Answer:

Hello

Step-by-step explanation:

You can take away the decimals

for example 0.33 x 0.7

do 33 x 7

which is 231

the 0.33 has 2 decimal spaces because there are 2 digits after the point

0.7  has 1 decimal place because there is 1 digit after the point.

so in total, there is 3 decimal

because you do 2 + 1

3

from the left, you count backwards and add the decimal point

the final answer should be 0.231

hope it helped

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Kim pays $90 for every block of 5 dance classes.

Here, Kim pays $90 for every block of 5 dance classes.

You need a picture of a graph so we can help.

A parabola with no real zeros, a negative leading coefficient, and an odd y-intercept.
pls help!

Answers

Answer:

Step-by-step explanation:

A parabolic graph with no real zeros never touches or crosses the x-axis.  

If the leading coefficient is negative, that tells us that the parabola opens down (and, in this case, that the entire graph is below the x-axis, because there are no real zeros.

If the y-intercept is odd, then the constant term, c, in ax^2 + bx + c, must be a negative, odd integer.

Suppose we say that the vertex of a particular parabola that is described by the above is (-2, -1) and that the y-intercept is -3.  (Note:  this is strictly an example.)  Then the vertex equation of this parabola is obtained from the general vertex equation of a parabola,

y = a(x - h)^2 + k.  Here h = -2 and k = -1, and so the particular parabola is

y = -a(x + 2)^2 - 1, where a is a constant and -a is negative.

In general form, this would be y = -a(x^2 + 4x + 4) - 1, or

                                                   y = -ax^2 - 4ax - 4a -1

and the constant terem (-4a -1) must be an odd negative integer

This is only one of an infinite number of possible equations for the parabola described above.

3x + 5y + 10
5x - 3y = -6

Answers

Answer:

3x + 5y + 10= 3

5x - 3y = -6

Step-by-step explanation:

1. m=-3/5

2. Simplifying

5x + -3y = 6

Solving

5x + -3y = 6

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

5x + -3y + 3y = 6 + 3y

Combine like terms: -3y + 3y = 0

5x + 0 = 6 + 3y

5x = 6 + 3y

Divide each side by '5'.

x = 1.2 + 0.6y

Simplifying

x = 1.2 + 0.6y

Hope this helps

X=1.2+0.6y this is the answer
