Write a pair of numbers such that the value of the 7 in the first number is 1000 times the value of the 7 in the second number,
telo118 [61]

<u>Answer-</u>

As infinitely many such possible number pairs can be formed, one of the instances of such pair would be (37000 and 307).

<u>Solution-</u>

Suppose the former one is aaaaa and the later one is bbbbb.

The value of 7 in the former is 1000 times greater than in the later, so let's make it 7000 and 7.

Then the numbers will be in the following form,

a7aaa and bbbb7

Again, the value of 3 in the former is 100 times greater than in the later.

Then the numbers will be in the following form,

37aaa and bb3bb7

Substituting all the a's and b's by 0,

we get, 37000 and 307 is a possible set. Replacing 0 with any number from 1-9, will yield another number pair which will satisfy the conditions.

The ratio of the height to the width of a packaging label is 5 to 19. If the height of the label is 1.5 inches, What is the widt
zhuklara [117]

Answer

Find out the  what is the width .

To prove

Let us assume that x be the scalar multiple of the height and width of the packaging label .

As given

The ratio of the height to the width of a packaging label is 5 to 19.

If the height of the label is 1.5 inches .

Than the equation becomes

5x = 1.5

x = \frac{1.5}{5}

x = 0.3

Than

The width of a packaging label = 19 × 0.3

                                                    = $ 5.7

Therefore the width of the packaging label is $ 5.7 .

From the sum of 3a^2−ab−2b^2 and 2a^2+5ab−3b^2 subtract a^2−3ab−4b^2
Lubov Fominskaja [6]
(3a^2-ab-2b^2) + (2a^2+5ab-3b^2) - (a^2-3ab-4b^2)

First we distribute the negative throughout the last polynomial:

(3a^2-ab-2b^2) + (2a^2+5ab-3b^2) + (-a^2+3ab+4b^2)

Combine like terms:

4a^2 + 7ab - b^2
