A number increased by 4 is the same as 19 minus 2 times the number

ElenaW [278]

Hello from MrBillDoesMath!

Answer:

n = 5

Discussion:

Let the original number be "n" Translating the problem statement to mathematical symbolism:

n + 4 = 19 - 2n => add 2n to both sides

n + 2n + 4 = 19 - 2n + 2n => combine like terms

3n + 4 = 19 => subtract 4 from both sides

3n = 19 -4 = 15 => divide both sides by 3

n = 15/3 =5

Check: Does 5 +4 = 19 - 2(5)? Does 9 = 9? Yes. so the value for n is confirmed correct.

Thank you,

MrB

Step-by-step explanation:

=> $\frac{\sqrt{19+6^2} }{7.2^2}$

=> $\frac{\sqrt{19+36} }{51.84}$

=> $\frac{\sqrt{55} }{51.84}$

=> $\frac{7.416}{51.84}$

=> 0.143059384

Hannah earned $1536 in 8 years on an investment at a 4% annual simple interest rate. How much was Hannah’s investment? $4800 $30

Nonamiya [84]

Simple interest calculates interest on initial amount only. The investment by Hannah was : Option A: $4800

<h3>How to calculate simple interest amount if rate of interest is R% annually?</h3>

Suppose that the initial amount of investment is P

And the rate of simple interest is R% annually,

And the time of investment is T years.

Then, the amount of simple interest is calculated as:

$I = \dfrac{P \times R \times T}{100}$

For the given case, let the initial investment Hannah made was of $P

Then, the time of investment is T = 8 years, R% = 4%, and given that Hannah earned interest I = $1536

Putting values in the above formula, we get;

$I = \dfrac{P \times R \times T}{100}\\\\1536 = \dfrac{P \times 8 \times 4}{100}\\\\P = \dfrac{153600}{32} = 4800$

Thus,

The investment by Hannah was : Option A: $4800
