Write down the rules for multiplication and division of whole numbers​

Mathematics

MAXImum [283]3 years ago

As division is the inverse of multiplication, the rules for division are the same as the rules for multiplication. So when multiplying and dividing positive and negative numbers remember this: If the signs are the same the answer is positive, if the signs are different the answer is negative.

What is the measure of the third angle?
SCORPION-xisa [38]
The total amount of degrees in a triangle is 180. All three angles should add up to 180˚

We know that 40+60 = 100

The next step is to do 180-100 to get the other angle.
180-100 = 80

So the measure of the third angle is 80˚

Hope this helps!

(Also if you want to do this in one equation, you would do 40+60+x = 180
40+60+x = 180
100+x = 180 (combine like terms)
x = 80 (Subtract 100 from both sides)

The highest scorer of the women's basketball championship was Jessica Bradley. She scored 114 more points than Tina Harner, her
Harman [31]

THIS IS AN EXAMPLE:

Answer: Bradley scored 854 points and Harner scored 748 points.

Step-by-step explanation:

Start by representing the problem mathematically.  "B" will represent Bradley's score, and "H" will represent Harner's score.

B+H=1602 represents that the sum of the scores is 1602.

B-H=106 represents that Bradley has 106 more points than Harner.

Now, combine the like terms in the two equations to get 2B=1708 .  Now divide each side by two to find that Bradley scored 854 points.

Now, we can just subtract Bradley's score from the total score to get Harner's score.  1602-854=748, so Harner scored 748 points.

Marisa bought four bottles of water.Each bottle of water was 95 cents. Write an equation with the same product as the total cost
meriva

Answer:

5\times 0.76= 3.8

Step-by-step explanation:

Given: Marisa bought four bottles

          Price of each bottle is $0.95.

Solving with the factors as given to find the total cost paid by Marisa.

Total cost= 4\ bottles\times \$ 0.95= \$ 3.8

∴ Total cost paid by Marisa is $3.8.

As given to write an equation with the same product as the total cost but different factors.

∴ Lets assume the number of bottles bought by Marisa be "5" and cost of each bottle be "x"

We already find the total cost she paid is $3.8.

Now, writing an equation with different factors, as total cost remain same.

5\times x= 3.8

Dividing both side by 5

we get x= $ 0.76

∴ The required equation is 5\times 0.76= 3.8
