What number can you multiply ONE equation by in the following system to obtain a matching

Mathematics

Answer:

Multiply the second equation by 2

Step-by-step explanation:

Given

4x + 3y = 8

2x + 5y =12

Required

Get matching coefficient for elimination

4x + 3y = 8

2x + 5y =12

The coefficient of x in both expressions are factors.

So, we can multiply the second equation by 2 to get the coefficient of x in the first.

i.e.

2 * (2x + 5y = 12)

4x + 10y = 24

So, the system becomes:

4x + 3y = 8

4x + 10y = 24

<em>Now, x can be eliminated</em>

How much should you put in an investment paying a simple interest rate of​ 5% if you needed​ $4000 in eighteen​ mont
Eddi Din [679]

now, there are 12 months in a year, so 18 months is really 18/12 of a year, thus

~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\dotfill & \$4000\\ P=\textit{original amount deposited}\\ r=rate\to 5\%\to \frac{5}{100}\dotfill &0.05\\ t=years\to \frac{18}{12}\dotfill &\frac{3}{2} \end{cases} \\\\\\ 4000=P[1+(0.05)(\frac{3}{2})]\implies 4000=P(1.075) \\\\\\ \cfrac{4000}{1.075}=P\implies 3720.93\approx P
