How can the Distributive Property help when you are multiplying by a two-digit number

Mathematics

eimsori [14]3 years ago

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

It states that when a number is multiplied by the sum of two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately, then adding the two products together for the same result as multiplying the first number by the sum.

Here, calculating 8 × 27 can made easier by breaking down 27 as 20 + 7 or 30 − 3.

Distributive Property is easy to remember if you recall that "multiplication distributes over addition".They write this property as "a(b + c) = ab + ac". In numbers, this means, 2(3 + 4) = 2×3 + 2×4.

The distributive property explains that multiplying two numbers (factors) together will result in the same thing as breaking up one factor into two addends, multiplying both addends by the other factor, and adding together both products.

I got this from google for a more definitive answer than my original.

I hope this helps, if not, comment below please!!!

Amount from dimes would be: 0.1y
Amount from quarters = 0.25x

So, total amount = 0.25x + 0.1y

So, she is not correct

PLEASE HELP! PLEASE ANSWER MY QUESTION PLS
andrew-mc [135]

Answer:

Tooth A

Step-by-step explanation:

Since the larger tooth has to be displayed, knowing that no matter how many zeros you add to the end of a decimal, the value of it will stay the same. 0.23 is 1 digit short that 0.195, so if you just add a 0 to 0.23, it make both of them have a digit in the thousandths place. Now it's easier to solve, 0.230>0.195.

Tooth A should be displayed.

Ebba is buying bulk fabric.
-Dominant- [34]

Answer:

To find the cost per yard, divide the cost by the amount:

p: 6.25 / 6.5 = 0.96  -->  The cost per yard is $0.96

r: 3 /4 = 0.75  -->  The cost per yard is $0.75

b: 8.1 /8.5 = 0.95  -->  The cost per yard is $0.95

s: 7.2 / 6 = 1.2  --> The cost per yard is $1.20

In order from cheapest to most expensive:

Red

Brown

Purple

Math Help!!! How many x-intercepts does the graph of the function have?
dalvyx [7]
It can have however many x intercepts it wants, 

<span>BUT, to be a function it must pass the vertical line test. </span>
<span>this means you have to look at the graph and see if a vertical line drawn anywhere hits the graph more than once. </span>
<span>if it hits it more than once, it is NOT a function. 
</span>
An example is a polynomial function to the infinite degree. That is 
f(x) = lim (n --> infinity) [ x^n] 
but only 1 y intercept (vertical line test remember)

A square field has an area of 144 metres squared. If Andrea walked 10 times around this field, what distance did she cover?
Novosadov [1.4K]

Answer:

480m

Step-by-step explanation:

First we have to find the perimeter of the field.

We know that the area is 144m and that the field is a square.

Since a squares sides are all equal, we can do \sqrt{144}, which is 12m.

So, one side of the field is 12m; now we just find the perimeter which is easy since its a square. 12*4=48m

If Andrea walked around it 10 times, then we just multiply the perimeter by 10

48*10=480m
