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!!!

Find the measure of the arc or angle indicated. NO LINKS.​
Advocard [28]

9514 1404 393

Answer:

  10.  A) 120°

  11.  D) 40°

  12.  D) 54°

  13.  A) 101°

Step-by-step explanation:

The applicable rules of angles and arcs are ...

  • the whole is the sum of the parts
  • arcs of a circle total 360°
  • an inscribed angle intercepts an arc of twice its measure

__

10) Angles C and L intercept the same arc (DE) so will have the same measure.

  15x = 16x -4

  4 = x . . . . . . . . add 4-15x

  arc DE = 2(15x) = 30(4) = 120 . . . degrees

__

11) Arc VW is twice the measure of angle X, so ...

  9x +8 = 2(5x)

  8 = x . . . . . . . . . subtract 9x

  ∠VXW = 5x = 5(8) = 40 . . . degrees

__

12) Arc EFG is twice the measure of angle W, so ...

  70° +FG = 2(88°)

  FG = 106° . . . . . . . . . subtract 70°

Arc FGW is twice the measure of angle E, so ...

  106° +GW = 2(80°)

  GW = 54° . . . . . . . . . . subtract 106°

__

13) Arc ST is twice the measure of angle R. The sum of arcs is 360°.

  RS +ST +TR = 360°

  119° +2(70°) +TR = 360°

  TR = 101° . . . . . . . . subtract 259°

Find the slope of the line that passes
lesya692 [45]

Step-by-step explanation:

Hey there!

Here, given;

The points are; (0,-2) and (5,3).

Now, simply use slope formula.

slope(m) =  \frac{y2 - y1}{x2 - x1}

<u>Put</u><u> </u><u>all values</u><u>. </u>

<u>m = \frac{3 + 2}{5 - 0}</u>

<u>Simplify</u><u> </u><u>them to get answer</u><u>. </u>

<u>m =  \frac{5}{5}</u>

<u>Therefore the</u><u> </u><u>slope is</u><u> </u><u>1</u><u>.</u>

<em><u>Hope</u></em><em><u> </u></em><em><u>it helps</u></em><em><u>.</u></em><em><u>.</u></em><em><u>.</u></em>

Need help putting domain and range into set notation.<br>The function is y = [1/2x]+1
Elanso [62]

Answer:

Domain=2, Range=1

Step-by-step explanation:

Domain and range are like x and y, or input and output. So I would assume it would be domain=2(from the slope) and range=1(from the slope and the y-intercept) I could be very wrong tho.

On average, the total number of electric guitars sold in Texas and Wyoming each year is 89,544. The average number of guitars so
Llana [10]
Given:
Texas and Wyoming Average = 89,544
Average of Wyoming = x
Average of Texas = 7x

7x + x = 89,544
8x = 89,544
x = 11,193 Average of Wyoming

7x = 7 * 11,193 = 78,351 Average of Texas
