Answer:

The required pair is 8.4 and 5.7

Step-by-step explanation:

Consider the provided information.

It is given that we need to find two different pairs of decimals whose sums are 14.1 and one pair should involve regrouping

Regrouping: Regrouping is know as borrowing or carrying numbers in order to add or subtract the provided numbers.

It is given that one pair should involve regrouping

Let us take the number are:

8.4 and 5.7

Now add them as shown:

8.4

First start with the right most digits which is 4 and 7 add them 4+7=11, 11 is a two digit number, so bring 1 down and carry 1. Now 8+5 = 13 now add the digit 1 as we carry it, which gives us = 13 + 1 = 14

8.4

Thus, the answer is 14.1

Hence, the required pair is 8.4 and 5.7

ariana starts with 100 milligram of a radioactive substance the amount of the substance decreases by 20% each week each number f

Anuta_ua [19.1K]

The required expression is 100 - 0.2w

Step-by-step explanation:

Given,

Amount of radioactive substance = 100 mg

The substance decreases by 20% each week.

To find the remaining amount of the in w weeks.

Now,

Each week 20% = 0.2 of the substance will be decreased.

So, in w weeks 0.2×w of the the substance will be decreased.

Hence,

The remaining substance = 100 - 0.2w

Someone please solve this 3n+9n=-2(7-4n)-(1+n)

Andru [333]

Answer:

Step-by-step explanation:

$3n+9n=-2(7-4n)-(1+n)\\\\\mathrm{Add\:similar\:elements:}\:3n+9n=12n\\\\12n=-2\left(7-4n\right)-\left(1+n\right)\\\\\mathrm{Expand\:}-2\left(7-4n\right)-\left(1+n\right):\quad 7n-15\\\\12n=7n-15\\\\\mathrm{Subtract\:}7n\mathrm{\:from\:both\:sides}\\\\12n-7n=7n-15-7n\\\\Simplify\\\\5n=-15\\\\\mathrm{Divide\:both\:sides\:by\:}5\\\\\frac{5n}{5}=\frac{-15}{5}\\\\Simplify\\\\n=-3$
