Sum of (x+5) and (2x+3)

Answers

Answer:

3x+8

Step-by-step explanation:

First, we can write the sum into a mathematical expression:

The sum of (x+5) and (2x+3)

(x+5)+(2x+3)

However, we do not need the parenthesis. It is unnecesarry here as we are just adding the two parts:

x+5+2x+3

Using commutative property, we can rearrange the symbols so that the x's are with each other and the numbers are with each other:

x+2x+5+3

Now we can simplify the expression:

3x+8

Hope this helped :)

Find the amount of the principal when the simple interest rate is 4.345%, the time is 7 months, and the amount of interest earned is $274.00.

Answers

tis noteworthy that 7 months is not even a year, since there are 12 months in a year then 7 months is really 7/12 of a year.

\bf ~~~~~~ \textit{Simple Interest Earned} \n\n I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill & \$274\n P=\textit{original amount deposited}\n r=rate\to 4.345\%\to (4.345)/(100)\dotfill &0.04345\n t=years\dotfill &(7)/(12) \end{cases} \n\n\n 274 = P(0.04345)\left( \cfrac{7}{12} \right)\implies \cfrac{274}{(0.04345)(7)/(12)}=P\implies 10810.46\approx P

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

The variable feet and yards are in direct proportion.

Let,

yard = k(feet).

1 = 3k

k = 1/3 = 0.33.
