2.75 x 5 = 13.75
20.00 - 13.75 = 6.25
$6.25
The mathematical property demonstrated by 7+9+3=7+3+9 would be the commutative property. This property states that in operations such as addition and multiplication, when you switch the order of the numbers around, the result will always be the same. In 7+9+3=7+3+9, no matter what order you put the numbers in, the answer will always be 19.
We are given : 62 hundreds and 30 tens .
To find : the number in standard form.
Soltuion: We know hundreds represents times 100.
Also tens reprents times 10.
In order to find the values of 62 hundreds, we need to multiply 62 by 100.
In order to find the values of 32 tens, we need to multiply 32 by 10.
62 × 100 = 6200
32 × 10 = 320.
Now, we need to add those numbers above.
6200 + 320 = 6520.
In simple, we could also show as
62 hundreds and 30 tens = 62 × 100 = 30 × 10 = 6200+300 = 6520.
Therefore, standard form is 6520.
The first column is x while the second is y. To find rate, you divide y by x. If each row has the same outcome, it is proportional.
First row:
9.00÷2= 4.50
Second row:
22.50÷5= 4.50
Third row:
31.50÷7= 4.50
There is a proportional relationship based off of the values.
So B, yes there is a constant of proportionality of $4.50.
